Hay is a carbohydrate, is the hay digested during fermentation? If so, is the volume of a CO2 bubble dependant on the size of the hay particle? Can you tell how big a hay particle was based on the size of its bubble?
The fact that we got good at making cheese, got too good to where it's too clean, then had to carefully and safely add barn dust to it in order to fix the cheese is absolutely amazing.
Remember something about a type of beer having the same issue. Seems like air flowing over the fermenting process from an old chimney had been adding some contaminates that added to its uniqueness.
@@EdBruceWRX probably, in belguim several beers can't be produces anywhere else then where they are, because they use the naturally occuring cultures to react SPONTANIOUSLY! thus a bit other naturally occuring yeast bacteria causes different reactions, and thus a slightly different beer.. also a lot of trapist beers use specific wells, with the water they start from partly determining the taste off the product :). i renember they tried to move Hoegaarden, they at least claim they got the taste right, (i never saw an option to taste it, so it's only some claim by the brewery to me) but not the color, thus it was not a white beer anymore, they reversed to physical merger interely, Hoegaarden is brewed at it's original location again, and color was normal again too :) .

I’m reminded of a whisky distillery I visited in Islay, Scotland. They installed a new still as the century’s old one was on the way out. They noticed they did not get the same flavour profiles, despite ensuring the product in was identical. Turns out the old dents and ‘imperfections’ in the old still changed how the sprit distilled. So they literally took a hammer to the new still and lo and behold they got the product out they wanted. A perfect blend of science, tradition and art.
There are swiss children out there who want to grow up and become cheese scientists. That is honestly such an incredible and hyperspecific job I'm slightly jealous
The Swiss have their Swiss Cheese Scientists, Americans have their Strategic Petroleum Reserve, and Canadians have their Maple Syrup Reserve including a Maple Syrup Heist.
Bubbles are such weird/interesting things, in that they need nucleation sites to form. (Otherwise the gas stays dissolved in solution.) Lack of nucleation sites is why boiled water can explode if boiled in extremely smooth, clean vessels. (In laboratories, they use little porous ceramic boiling stones to go in their flawlessly smooth boiling flasks.) Or why they now laser-etch little imperfections into the bottom of beer glasses, to give the bubbles somewhere to form. It’s why Diet Coke goes berserk when you drop a Mentos into it (the surface has a huge amount of nucleation sites).
It makes sense in retrospect. Every hole is a separate nucleation site, and each nucleation site only needs one tiny particle (possibly as small as a single molecule) to happen. 1 milligram has a LOT of particles.
I've worked in protein crystallization, also a very finicky process. One lab can get crystals while another one doesn't despite using the same protocol. Crystals need something to grow around, a nucleation point, one lab where people smoked (this was long ago) got crystals while others didn't. It's the small things...
@@janfilby7086 Yes. Another example where one lab got crystals and another one didn't it turned out the lab that got crystals had algae growing in the distilled water system. Sometimes a little dirt is a good thing, like how penicillin was discovered 🙂
While holes do not affect the taste (flavour), they do have great effect on texture. And texture is very important in forming the complete experience of the taste.
Regardless in and of how irrational this may seem to some, there is a psychology that can come into play here. It is not a "just in your head" kinda thing. For my Rubin Sandwich, the Swiss layer has to have holes.
Holes certainly do affect the taste. Because many swiss cheese makers in the US use a different process that is quicker and doesn't form holes, which results in a much blander cheese, which shouldn't be called swiss cheese at all, it's false advertising, because the flavor intensity difference is huge. The holes themselves are indicative of flavor. Although many US manufacturers of "swiss" cheese, add holes mechanically with machines that effectively randomly cut small round pieces out of the cheese to simulate the holes. It's ridiculous.
To have one understand how particular the cheese industry is about their homemarket IN Switzerland one only has to make a little taste test with Gruyere cheese. The one you can buy in Germany, even though directly bordering Switzerland does not taste quite as distinct as the one you can get in Switzerland. I always suspect that is because they keep the real good stuff to themselves.
That is not my experience as someone who lives in Tessin: what I have noticed is that, as far as Italy is concerned, exported Swiss cheese tends to be tastier than the locally sold product. I wouldn't however be surprised if retailers were selling lower choice products here, though.
Knowing that I could've been a _cheese scientist_ instead of a programmer is perhaps the most tragic thing I've ever learned... thanks, Tom. Thanks a lot. -_-;;

@yyattt That there is gold buried on my local beach, although it was only done a few years ago. I hadn't heard a thing about it, although it apparently caused a stir locally. I think someone had to be extracted from the harbour mud by the local rescue team, to avoid getting drowned by the incoming tide.

There is a metaphor in medicine (and other industries) about a Swiss Cheese model - where each layer of a service has certain vulnerabilities (holes) but using more layers helps stop there being a vulnerability which runs through the whole system unchecked (or a hole all the way through the cheese). I think the fact that the holes in Swiss cheese are created by very slight imperfections in the milk fits well with this analogy as the vulnerabilities of a system are often slight imperfections which how the real world works.
The thing is that it's not really swiss cheese if it has holes it's French cheese called Gruyère but anglos can't make the difference so it's all swiss cheese to them
@@kala_asi I'm looking forward to finding an issue and saying "Hey! That's hay!" and then going on a ramble about the Swiss cheese model and then about this video where they add hay to cheese to make the holes. I'm confident that the more longwinded a metaphor is the more effective it is.
They do. Except it's not really cheese. It's pasteurized prepared cheese product. Kraft makes it, just like they make American cheese which isn't really cheese either. Although I think it would be "unholey".
As a cheese enthusiast, this makes me proud to be Swiss. I always liked the high varieties we have here, as we have hard and soft cheeses. Also on a sidenote: the Swiss recently lost a legal battle in the US; they were fighting for the recognition of the AOP Gruyère so that cheesemakers in the US aren't allowed to falsely label their cheese as Gruyère. Unfortunately they lost this one. I'm still a bit mad about that.
Perhaps if y’all hadn’t behaved the way you did 85 years ago, and perhaps if you had sided with your neighbors during the Cold War, then things might be different today.
Whenever you see "Our X doesn't do Y as much anymore", it's 95% of the time because we've become so good at doing something, that we lose the small imperfections that make it great. I'm reminded of a recent HAI video in fact: Fogbank. We reverse-engineered the process of making it, but our modern processes are so pure and refined, that we lost the imperfections that made the compound so effective. Like the Swiss Cheesemakers here, we had to add it back in.
Flashback to Veritasium where Derek explained that Roman Concrete™ was mixed by hand which resulted in irregularities in the mixture and gave it some self-healing properties thanks to some uncured leftover unlike modern concrete which is more evenly mixed and cures more uniformly.
Maybe it doesn't affect the taste, but it quite literally affects mouthfeel/texture on like, a macro scale. It's so much fun to bite into cheese holes.
Reminds me a bit of when Spotify had to make their "shuffle" less random, because people lost their mind when 2 similar songs happened to be played one after the other.
Now, Tom, this is _really_ something I did not now! (I know this is not the title of the series any more, but still...) So, only one part per billion of finely ground hay is what makes the difference! And they use CT to count cheese eyes, and DNA sequencing to check authenticity! Amazing!

there is something that warms that heart of me that knows that we have bred specific cultures of bacteria for specific purposes since before we knew what bacteria was.
I'm getting my PhD in microbiology, immunology and virology so videos like this are always interesting. Reminds me of one of my favorite professors Dr. Oberg. He was our food micro prof and his research was cheese. He had studies just documenting all the types of bacteria in cheeses and he alone and found so many new types of bacteria that were otherwise unknown. I think he retired a year or 2 ago though.
I said the same thing to myself. Like I spend as much of my day as possible learning new things, and it's not often a new incite or view point or science peaks as much intrigue as this video.
It is always fascinating to see how "imperfections" in products that historically existed due to imprecision in methodology which we subsequently consciously removed prove to be extremely important to key features of the product: distilleries, rockets, and now cheeses.
It's interesting how imperfections become a part of tradition over time. The people who discovered swiss cheese many centuries ago might have preferred less imperfections, given the chance.
so much of brewing, baking, and cheese making is wrapped up in traditions because they did not know how or why the food production worked. Superstition dominates because they thought if you didn't do the superstition the spirits would get angry at you and you didn't get any cheese
The video is interesting and informative as always, but can we appreciate the absolute gem of a reference in the thumbnail ("something un-holey")! Way to keep up with the trends, Tom
I assume that the hay dust acts as a nucleation point, like dust particles seeding raindrops or tiny imperfections in a Champagne flute being the source of the bubbles.
@@kaitlyn__L it probably would taste more acidic if you ate it quickly after the cheese is formed - but cheeses rest for months so all the co2 will have bled out anyway. From both the holes and any remaining in solution.
Remember, no one likes something that's too perfect. Embrace your imperfections, and while it may seem you're lacking something, it's actually what makes you special. *me talking to a wheel of Swiss cheese I'm about to devour*
You seem to like Switzerland a lot. I hope you have many more projects with us. I always learn something new about us Swiss and like your view from „the outside“. 👍
I think it's moreso that Switzerland seems to like Tom Scott a lot. I'm sure there's an amount of Tom cold emailing companies asking if he can make videos with them, but I think based on Tom's popularity and openness in having people send in their queries to him, it looks like companies are the ones cold-emailing Tom to see if he wants to work with them haha!
The distinction is to be made as Gruyère is not Emmental or what you call swiss cheese is not Swiss either if it has holes it's from France and it's also called Gruyère and made only in the Alp region
@@suspicioustumbleweed4760 Gruyère made in France origin is also protected as a Protected Geographical Indication (PGI) in the EU. At least do some search before saying ldlotlc stuff...
It is somewhat terrifying how much leverage "big cheese" has. They can hire whole teams of scientists to maintain their elite status. It's like the high table in john wick, but instead of assassins, it's cheese oligarchs.
I lived in Switzerland for 3 years and I loved the cheese. I bought most of my weekly cheese every wednesday from a small food-truck in front of a Toom-Market. It came from a small dairy 75 km away.
Fascinating! That as a byproduct of hay dust, bacteria munched on it and made the holes! YET! This story shows how things are lost when you become a conglomerate, you loose something! Reading my cheese book years ago, it mentioned that smaller, independent cheese producers, who made only a few wheels of cheese in a day, could use unpasteurized milk for even soft cheeses because if something went wrong, the cheese would smell and look bad. Since you did not have HUGE quantities such a problem would not ruin much. Also each dairy would have slightly different cultures dependent on the environment. It's a good thing to see that Agroscope preserved all this genetic diversity. It allows them to try new things and perhaps come up with a different take on a type of Swiss cheese that becomes the next big thing!
I remember following this as it happened in real time. The fact that something could be "too clean" was fairly new to the popular mind. (At least, that's how it was in the US, where I live. )
Thank you for answering a question I've genuinely had for years (and was too lazy to research myself). Very interesting! Especially as I love Swiss cheeses. :D
Well as somebody who like Swiss cheese and Swiss type cheeses this was fascinating it also explains why there was a sudden rise of small old Swiss cheese in the market a few years back. And putting hay powder a.k.a. grass a.k.a. greens in that makes sense and it's kind of cool.
That's so interesting about the milk. I wonder if because milk is cleaner these days and no hay particles get in it, that could be linked to the rise in hay pollen allergies, milk allergies and lactose intolerance? I tick 2/3 of those and have an autoimmune disease (coeliac) as well, and the steep rise in these things fascinates me.
it has been proven that living in too sterile environments will cause you to get more sick, because you're not exposed to everyday bacteria, so your immune system isn't tuned to dealing with them. But allergy to one thing isn't necessarily caused by not being exposed to that one thing. You can grow up in a humid/moldy house and end up allergic to cats for instance.
@@ng.tr.s.p.1254 Worldwide, more people are lactose intolerant than not. The only reason that cultures with a heavy dairy consumption culture seem to be fine is that, well, they weren't. When milk and milk derived products are your only source of some very essential nutrients, the kids who couldn't digest it properly just straight up would've had a a very, very hard time reaching adulthood. Lactose intolerance eventually got eliminated from those ethnic groups as a result.
@@thesteelrodent1796 I used to get sick all of the time as a child. Even though I grew up on a farm, my parents kept me isolated from the rest of the world, but they also brought back germs every time they returned from work. Now that I go to work myself and am out among society at least 5 days a week, I rarely ever get sick. Go figure.
Actually this reminds me of Fogbank, same situation, US couldn't make it because the impurities we're filtered, and they we're essential to make this chemical work as intended.
Almost fell off my chair when you mentioned Agroscope, because they have a site in my town! 😄 (One of the 12 sites and unfortunately not the one you've been to. The one in my place seems to be focused mainly on farming techniques and machines/utilities.)
so they saw their cheese suddenly gain more cheese per cheese and went "hold on, why is there more cheese per cheese and not the usual less cheese for more cheese?" which in turn made them research ways to remove cheese from more cheese so it goes from more cheese to less cheese per more cheese. and now the end result is they can now sell more cheese with less cheese.
Thank you Tom for this video. This was so interesting ! I wish I could have been part of the superhero team that would "restore the holes in Swiss cheese"
As one who most times consumes home made cheese (one way to deal with excess milk during period when it is not worth selling it to milk-truck), whenever I do buy some, i often like one with holes. It kind of gives different taste feeling (yes, cheese will have it's taste overall but holes kind of gives extra contact surface that tastes a bit different than cut line surface). Cheers and let the holes stay big and many. For cheese too.
I worked in a bakery when i was younger, 19 years old fresh out of school. After 2 years they decided to upgrade the machinery and all of a sudden some bread we made didnt taste like they used to and didnt rise as they used to. Turned out that the old kneading machines had been contaminated with yeast that was alive and well and didnt need to get activated. So the bread started to rise earlier and did it more slowly, which made them rise slower but over a longer period of time. So one day we had to rub activated yeast into the kneading machines. The new machines also had an automated cleaning function we had to turn off, and then the bread we made started to taste as they used to do.
This week I seem to have inadvertently learned the answer to the question "why is Swiss cheese like nuclear bombs?" - I heard elsewhere that the US military never wrote down how to make the bombs' secret ingredient "Fogbank" and all attempts to refurbish their old bombs failed... Until they realised the impurities in the old ingredients were what made it work.
No, that little factoid about nukes is completely false. In fact, it's so completely full of holes (see what I did there?) that it almost certainly originally came from some kind of joke or satire site.
@@HiddenWindshield Really? I've seen Fogbank discussed in numerous reputable sources as fact (as much as a well-kept national secret ever is at least), and can find none discrediting it, such as is the case with Red Mercury. Do you have any references that connect the discussions of Fogbank to a disreputable origin?
@@magma2050 Okay, so I initially dismissed "Fogbank" out of hand, because even during the cold war we knew what nukes were made of, and "Fogbank" wasn't one of those materials. But, as it turns out, Fogbank does exist. It isn't a component of nukes in general, but it is a component of certain specific designs.
Nice to see X-ray computed tomography (XCT) represented in the cheese world 🧀. You could segment the bubbles and do a bubble density analysis. I wonder if different bubble layouts enhance the cheese experience? 😂
I don't think this changes the weight of the cheese Only difference is if tge gasses are diffusely distributed in the cheese, or concentrated around holes
I cannot believe we went from accidentally discovering that cow milk is kinda rad when it goes bad, to profitable, dedicated teams of scientists analyzing cheese holes.
Amazing job by the camera op and whoever directed, there were some outstanding takes here. Tom has come a long way since recording stuff with a gopro or iphone!
Reminds me of the fogbank story. There too, the new process didn't have the impurities of the old process. Fascinating how much we still have to learn about the most simple things around us.

There is a metaphor in medicine (and other industries) about a Swiss Cheese model - where each layer of a service has certain vulnerabilities (holes) but using more layers helps stop there being a vulnerability which runs through the whole system unchecked (or a hole all the way through the cheese). I think the fact that the holes in Swiss cheese are created by very slight imperfections in the milk fits well with this analogy as the vulnerabilities of a system are often slight imperfections which how the real world works.
The thing is that it's not really swiss cheese if it has holes it's French cheese called Gruyère but anglos can't make the difference so it's all swiss cheese to them
So now we know services can be made more robust by refusing to add the hay!
@@ommsterlitz1805 Why would Gruyère cheese be French, when the town of Gruyères is in Switzerland?
@@kala_asi I'm looking forward to finding an issue and saying "Hey! That's hay!" and then going on a ramble about the Swiss cheese model and then about this video where they add hay to cheese to make the holes. I'm confident that the more longwinded a metaphor is the more effective it is.
Oh, wow! I heard the same metaphor with regard to cybersecurity! 😎🤘☮️
They should make "unholy swiss cheese" as a brand. I'd buy it.
Jesus wouldn't be happy
@@lighghthe's long gone so we're completely fine
They do. Except it's not really cheese. It's pasteurized prepared cheese product. Kraft makes it, just like they make American cheese which isn't really cheese either. Although I think it would be "unholey".
Get more cheese per volume of cheese!
They could recruit Sam Smith for the ad campaign ;)
The camera quality on this video is outstanding. Tom's come a long way from filming on a GoPro by the side of the road.
I mean, without Tom Scott, I would have never imagined there would be a cheese bacteria archive. Keep doing the good work
As a cheese enthusiast, this makes me proud to be Swiss. I always liked the high varieties we have here, as we have hard and soft cheeses. Also on a sidenote: the Swiss recently lost a legal battle in the US; they were fighting for the recognition of the AOP Gruyère so that cheesemakers in the US aren't allowed to falsely label their cheese as Gruyère. Unfortunately they lost this one. I'm still a bit mad about that.
Perhaps if y’all hadn’t behaved the way you did 85 years ago, and perhaps if you had sided with your neighbors during the Cold War, then things might be different today.

Whenever you see "Our X doesn't do Y as much anymore", it's 95% of the time because we've become so good at doing something, that we lose the small imperfections that make it great. I'm reminded of a recent HAI video in fact: Fogbank. We reverse-engineered the process of making it, but our modern processes are so pure and refined, that we lost the imperfections that made the compound so effective. Like the Swiss Cheesemakers here, we had to add it back in.
Flashback to Veritasium where Derek explained that Roman Concrete™ was mixed by hand which resulted in irregularities in the mixture and gave it some self-healing properties thanks to some uncured leftover unlike modern concrete which is more evenly mixed and cures more uniformly.
@@MarioFanGamer659 Wasn't roman concrete self healing cause they used saltwater?
Shows the importance of continually refining processes. You have to get good enough to manipulate something to be able to completely understand it.
Maybe it doesn't affect the taste, but it quite literally affects mouthfeel/texture on like, a macro scale. It's so much fun to bite into cheese holes.

May I just say, this video has the smoothest transition from the thumbnail to the actual video that I've ever seen? It's so seamless!
I think that "artificial imperfections" are always very entertaining to learn about.
Reminds me a bit of when Spotify had to make their "shuffle" less random, because people lost their mind when 2 similar songs happened to be played one after the other.
Now, Tom, this is _really_ something I did not now! (I know this is not the title of the series any more, but still...) So, only one part per billion of finely ground hay is what makes the difference! And they use CT to count cheese eyes, and DNA sequencing to check authenticity! Amazing!
As a swiss I feel maximal pleasure! Amazing! Thank you Tom

there is something that warms that heart of me that knows that we have bred specific cultures of bacteria for specific purposes since before we knew what bacteria was.
I'm getting my PhD in microbiology, immunology and virology so videos like this are always interesting. Reminds me of one of my favorite professors Dr. Oberg. He was our food micro prof and his research was cheese. He had studies just documenting all the types of bacteria in cheeses and he alone and found so many new types of bacteria that were otherwise unknown. I think he retired a year or 2 ago though.

I said the same thing to myself. Like I spend as much of my day as possible learning new things, and it's not often a new incite or view point or science peaks as much intrigue as this video.
Love the käsual joke in the description
It is always fascinating to see how "imperfections" in products that historically existed due to imprecision in methodology which we subsequently consciously removed prove to be extremely important to key features of the product: distilleries, rockets, and now cheeses.

It's interesting how imperfections become a part of tradition over time. The people who discovered swiss cheese many centuries ago might have preferred less imperfections, given the chance.
Fewer
i prefer the holeless cheese
so much of brewing, baking, and cheese making is wrapped up in traditions because they did not know how or why the food production worked. Superstition dominates because they thought if you didn't do the superstition the spirits would get angry at you and you didn't get any cheese
@@BlueCameNext yes, easier to work with when cooking, but esthetically I actually like the holes

For some reason, I expect nothing less than this level of dedication by the Swiss.
This video, along with the past few ones, have been beautifully shot/directed, even more so than usual!
After hearing the word cheese so much I decided to make a grilled cheese sandwich and it was delicious. Thank you Tom Scott
The video is interesting and informative as always, but can we appreciate the absolute gem of a reference in the thumbnail ("something un-holey")! Way to keep up with the trends, Tom
Makes sense... but I never figured bacteria would need a nucleation site to produce carbon dioxide
Not to produce carbon dioxide, for it to be released from solution quickly enough in one location to form a bubble.
The bacteria produce CO2 regardless.
It just stays dissolved in the cheese otherwise, which I suppose might make it taste a bit more acidic?
I assume that the hay dust acts as a nucleation point, like dust particles seeding raindrops or tiny imperfections in a Champagne flute being the source of the bubbles.
@@kaitlyn__L it probably would taste more acidic if you ate it quickly after the cheese is formed - but cheeses rest for months so all the co2 will have bled out anyway. From both the holes and any remaining in solution.
I can't describe how much I aprecciate you traveling to switzerland and explaining this incredible unheard of process, just for a funfact.

You seem to like Switzerland a lot. I hope you have many more projects with us. I always learn something new about us Swiss and like your view from „the outside“. 👍
I think it's moreso that Switzerland seems to like Tom Scott a lot. I'm sure there's an amount of Tom cold emailing companies asking if he can make videos with them, but I think based on Tom's popularity and openness in having people send in their queries to him, it looks like companies are the ones cold-emailing Tom to see if he wants to work with them haha!
I've always wondered why the holes exist! This is amazing.
I am amazed at how the holes actually emerge. Thanks for clarifying the misconception!
Fascinating, start to finish... I would not have guessed that a higher quality standard would've lead to a reduced perception.
Cheese: Less holes, smaller holes.
Switzerland Goverment: Save cheese holes!!!!!!
The distinction is to be made as Gruyère is not Emmental or what you call swiss cheese is not Swiss either if it has holes it's from France and it's also called Gruyère and made only in the Alp region
Fewer holes
For the US it would be "save the assholes", particularly in government.
@@ommsterlitz1805 you’re completely wrong
@@suspicioustumbleweed4760 Gruyère made in France origin is also protected as a Protected Geographical Indication (PGI) in the EU. At least do some search before saying ldlotlc stuff...
It is somewhat terrifying how much leverage "big cheese" has. They can hire whole teams of scientists to maintain their elite status. It's like the high table in john wick, but instead of assassins, it's cheese oligarchs.
I misread the title as "How they saWed the holes in Swiss cheese" and was very excited to learn about the art of sawing holes in cheese.

I lived in Switzerland for 3 years and I loved the cheese. I bought most of my weekly cheese every wednesday from a small food-truck in front of a Toom-Market. It came from a small dairy 75 km away.
There are no Toom-markets in Switzerland.
How much do you spend on cheese every week?
seems that you thought to live in Switzerland for 3 years, but accidentaly lived in Germany 😂
@@huberteichson8304 It was 2007 and I spend 100 CHF on average. More when I visited Germany or had night shift the week before.
This has no right to be as interesting as it is. Then again, I can say that about every video Tom and his team have made. Cheers!
Fascinating! That as a byproduct of hay dust, bacteria munched on it and made the holes!
YET! This story shows how things are lost when you become a conglomerate, you loose something! Reading my cheese book years ago, it mentioned that smaller, independent cheese producers, who made only a few wheels of cheese in a day, could use unpasteurized milk for even soft cheeses because if something went wrong, the cheese would smell and look bad. Since you did not have HUGE quantities such a problem would not ruin much. Also each dairy would have slightly different cultures dependent on the environment.
It's a good thing to see that Agroscope preserved all this genetic diversity. It allows them to try new things and perhaps come up with a different take on a type of Swiss cheese that becomes the next big thing!
I remember following this as it happened in real time. The fact that something could be "too clean" was fairly new to the popular mind. (At least, that's how it was in the US, where I live. )
5:33 tom didn't have to go cinematic with the moving camera while talking about cheese, but he still did anyway
Thank you for answering a question I've genuinely had for years (and was too lazy to research myself). Very interesting! Especially as I love Swiss cheeses. :D
The cinematography in this episode is gorgeous! Props to the camera crew.
Love the description pun. Thank you
Well as somebody who like Swiss cheese and Swiss type cheeses this was fascinating it also explains why there was a sudden rise of small old Swiss cheese in the market a few years back. And putting hay powder a.k.a. grass a.k.a. greens in that makes sense and it's kind of cool.
When the leftist environmentalists learn that swizz cheese produces CO2 they'll run for a global ban of this poisonous and dangerous product
That's so interesting about the milk. I wonder if because milk is cleaner these days and no hay particles get in it, that could be linked to the rise in hay pollen allergies, milk allergies and lactose intolerance? I tick 2/3 of those and have an autoimmune disease (coeliac) as well, and the steep rise in these things fascinates me.
it has been proven that living in too sterile environments will cause you to get more sick, because you're not exposed to everyday bacteria, so your immune system isn't tuned to dealing with them. But allergy to one thing isn't necessarily caused by not being exposed to that one thing. You can grow up in a humid/moldy house and end up allergic to cats for instance.
I mean we’re not supposed to drink it, it’s for cows
@@unethicallyvoid2888 Go tell that to prehistoric people.
@@ng.tr.s.p.1254 Worldwide, more people are lactose intolerant than not. The only reason that cultures with a heavy dairy consumption culture seem to be fine is that, well, they weren't. When milk and milk derived products are your only source of some very essential nutrients, the kids who couldn't digest it properly just straight up would've had a a very, very hard time reaching adulthood. Lactose intolerance eventually got eliminated from those ethnic groups as a result.
@@thesteelrodent1796 I used to get sick all of the time as a child. Even though I grew up on a farm, my parents kept me isolated from the rest of the world, but they also brought back germs every time they returned from work. Now that I go to work myself and am out among society at least 5 days a week, I rarely ever get sick. Go figure.
I don’t even like cheese and I’m watching this. That’s the power of Tom Scott.
Are you from the US?
How freaking cool is this story!?! And how on earth do you find them!?!? Thanks so much for bringing them to videos, I love your work.
Actually this reminds me of Fogbank, same situation, US couldn't make it because the impurities we're filtered, and they we're essential to make this chemical work as intended.
Almost fell off my chair when you mentioned Agroscope, because they have a site in my town! 😄
(One of the 12 sites and unfortunately not the one you've been to. The one in my place seems to be focused mainly on farming techniques and machines/utilities.)
so they saw their cheese suddenly gain more cheese per cheese and went "hold on, why is there more cheese per cheese and not the usual less cheese for more cheese?" which in turn made them research ways to remove cheese from more cheese so it goes from more cheese to less cheese per more cheese. and now the end result is they can now sell more cheese with less cheese.
...with sawdust.
This is one of the best and most interesting videos you have ever made! As someone with a background in food technology, this makes so much sense!
So the eyes of cheese are a lot like pearls in oysters in more ways than one. I never would have thought!
Thank you Tom for this video.
This was so interesting !
I wish I could have been part of the superhero team that would "restore the holes in Swiss cheese"
Nice video, Tom! :) All the best from Switzerland from German expat ~ Mad
As one who most times consumes home made cheese (one way to deal with excess milk during period when it is not worth selling it to milk-truck), whenever I do buy some, i often like one with holes. It kind of gives different taste feeling (yes, cheese will have it's taste overall but holes kind of gives extra contact surface that tastes a bit different than cut line surface). Cheers and let the holes stay big and many. For cheese too.
You whole deal is part of the best sides of TH-cam culture
I worked in a bakery when i was younger, 19 years old fresh out of school. After 2 years they decided to upgrade the machinery and all of a sudden some bread we made didnt taste like they used to and didnt rise as they used to. Turned out that the old kneading machines had been contaminated with yeast that was alive and well and didnt need to get activated. So the bread started to rise earlier and did it more slowly, which made them rise slower but over a longer period of time. So one day we had to rub activated yeast into the kneading machines. The new machines also had an automated cleaning function we had to turn off, and then the bread we made started to taste as they used to do.
This week I seem to have inadvertently learned the answer to the question "why is Swiss cheese like nuclear bombs?" - I heard elsewhere that the US military never wrote down how to make the bombs' secret ingredient "Fogbank" and all attempts to refurbish their old bombs failed... Until they realised the impurities in the old ingredients were what made it work.
No, that little factoid about nukes is completely false. In fact, it's so completely full of holes (see what I did there?) that it almost certainly originally came from some kind of joke or satire site.
@@HiddenWindshield Really? I've seen Fogbank discussed in numerous reputable sources as fact (as much as a well-kept national secret ever is at least), and can find none discrediting it, such as is the case with Red Mercury. Do you have any references that connect the discussions of Fogbank to a disreputable origin?
@@magma2050 Okay, so I initially dismissed "Fogbank" out of hand, because even during the cold war we knew what nukes were made of, and "Fogbank" wasn't one of those materials. But, as it turns out, Fogbank does exist. It isn't a component of nukes in general, but it is a component of certain specific designs.
(I had more info, but TH-cam's being a pain again, so I had to cut it _way_ down to get the post to go through.)
There is an obscure novella from the 18th century which also talks about hunting an elusive impurity: The Strange Case of Dr Jekyll and Mr Hyde.
Nice to see X-ray computed tomography (XCT) represented in the cheese world 🧀. You could segment the bubbles and do a bubble density analysis.
I wonder if different bubble layouts enhance the cheese experience? 😂
What you're saying is that fewer holes means cleaner milk used in the cheese? Of course, that is until they purposefully add hay powder.
this is easily one of the best channels in youtube.. at least for us who love very niche but also very interesting stories
When you get serious about things, even simple stuff can get soo detailed!
It's crazy that there's this much dedication to producing _less_ cheese.
I don't think this changes the weight of the cheese
Only difference is if tge gasses are diffusely distributed in the cheese, or concentrated around holes
Next Tom will do the research about why some kids believe that the moon is made out of cheese
I cannot believe we went from accidentally discovering that cow milk is kinda rad when it goes bad, to profitable, dedicated teams of scientists analyzing cheese holes.
Amazing job by the camera op and whoever directed, there were some outstanding takes here. Tom has come a long way since recording stuff with a gopro or iphone!
Reminds me of the fogbank story. There too, the new process didn't have the impurities of the old process. Fascinating how much we still have to learn about the most simple things around us.
