Try this again with these conditions: 1 bottle no purge no foam cap, 1 bottle itap purge no foam cap, 1 bottle itap purge foam cap, 1 bottle soda flush + itap purge cap on foam. Let them all sit for 6 weeks. See if any make a difference. Suspect the itap side filling action prevents most of the o2 contact and its pushed out with the foam cap.
Great video :) I recently opened two bottles that were bottled with the Boel itap 6 months ago. The beer was wonderfull, which surpriced me actually. The Itap is awesome
Another interesting experiment! For me, the results point to the efficiency of pressure fermenting when it comes to keeping oxygen out of the equation, rather than the effectiveness of flushing a bottle with CO2 (or not). (And, also, the effectiveness of your bottling technique!) You are transferring beer to the bottle that is already carbonated and saturated with CO2, and, added to this, you are also squeezing the bottle so that beer reaches the opening and pushes any O2 out before capping. Once capped, the dissolved CO2 present in the beer release to fill the headspace. Which brings me to the final point, which is the headspace in a bottle is already very small, so by doing this you are effectively eliminating pretty much all O2, regardless of whether the bottles were preflushed with CO2. I believe that if the beer hadn't been squeezed to the top of the bottle before capping, and the headspace was larger, then the results may well have been different. The great news is that it IS possible to bottle NEIPA without suffering oxidation - at least for a week or so, anyway. Keep up the great work!
I'm in the 'a week isn't long enough to oxidise' camp. Shame you didnt just leave it another few weeks doc! most of my bottled from bucket beers didn't really oxidise much until week 3
Awesome video man! Would love a video where you bottle straight from the fermzilla and let it sit for a month or two. I think a lot of people (including me) don’t have the money or space for a keezer, so i think it would be very interesting to see the effect on the beer if it stays bottled for longer.
Thanks for doing this video. As I commented on the previous video - my bottles oxidised before being sold to a shop using the itap. Mine were fine the 1st week. The 2 week mark, all oxidised. However, I still have around 30 bottles in the fridge 2-3 months on, and they aren’t any further oxidised to how they were at the 2 week point. Also still taste reasonable but just not as fresh as when dispensed from the keg
Don't be dissapointed. Another great video. What we do know is that if theres a difference, it does not show in a week. That is good to know. This also shows your fermentation and transfer is clean. An ecouragement to maintain clean process. Therefore proof two things, excellent. Maybe a 'bad' control would have been a half fill bottle 'unflushed' and shake it. I'm sure the oxygen would have ruined the beer, right? But what if we don't shake it. Will C02 push oxy to the top and keep the beer good. Maybe an experiment. Cheer doc.
Also I think you can cut down on the amount of iTap samples and add another using a 'ghetto blaster' - it would be interesting to see if there's any difference.
I really appreciate this video and research! I've been lead to believe crown caps can let air in. That might make a difference. Good to know PET bottles are reliable and we don't need to be too serious about purging the headspace.
Transparent bottles, nevermind the vacuum bags and have a control bottle intentionally treated badly - perhaps poured from a pitcher* or straight from a regular tap with into the bottle. *although you might have to force carbonate that bottle as well then, to account for any loss of co2?
Vitamin C is getting a space in my heart, I use it to guarantee no Chlorine in my initial water. I over do-it but maybe I can split a tablet between beginning and end of brew-day.
Great stuff, I would love to see it done over a longer period. How would it be after a month maybe, your process is obviously dialed in. Also was thinking adding Ascorbic Acid into the mix, at bottling vs boil might be fun for a split boil batch test too!
it might be interesting to show a more extreme difference in oxidation potential. ie filling a bottle directly from a party tap with no purging vs use of the boel itap. I appreciate what you were trying here, but given the results, which are still valid and useful, didn't show any perceptible difference, this might be the next step
If you squeeze the bottle removing all Oxygen carrying air before capping there will be no Oxygen to oxygenate. This would mean flushing is a waste of gas and time. But one flush probably best to be super sure. Why ascorbic acid? What does that do other than adjust PH? I’ve seen you add a citric acid to the mash for PH.
Hi! Squeezing the bottle after its filled does not ilminate oxygenation during the filling. It does a great job removing the head space as you mention. Which is great. Ascorbic acid is an antioxidant. I can't remember using citric acid (but it will work to adjust PH). I've used lemon 🍋 juice though for PH adjustment together with lactic acid in one brew.
@@DrHansBrewery Yes it was Lactic acid you used not citric. You put 2 caps in a 23L batch. Thanks for information and for your work on the vids. I watch them all.
Shouldn't vacuum sealed the bottles to allow the natural pressure difference to effect it and also you should have waited 8-12 weeks I bottle condition my beers and I don't ferment under pressure and my neipas with 500-600 grams of hops for 19 litre batch dont get the oxidation until it been in bottles for over 4 weeks and that is without flushing the bottles with co2 when bottling
@@DrHansBrewery I have used the picnic tap to tap the beer from plastic cap but it didn't fizzy as i pour it out but by hand(like pouring the soda bottle). The fizzy dramatically differrent but i try to buy some pressure filler to fill it to the bottle but I 'm not sure, Is it gonna work well ?
Looking at it wrong way round buddy! Experiment doesn't suck... experiment shows the iTap does a great job and you don't need to faff about. Success I'd say
@@mtrout3394 yes, now we know that you should be able to ship sensitive beer mails in one week without issues. Now I can take it further. It's an awesome base to stand on.
From what I've learned a strait pour from a keg is good for 24hrs. With flushing, 1 week. Closed loop transferring and flushing, up to one month. Even commercial hazies start going bad by 2mo.

Hey Dr Hans, one week is not long enough for effects of oxidation to activate. You should wait 2-3 months then sample..
2-3 months is the lifespan of a hazy. Even commercial hazies will be going bad by then. For a homebrew hazy you're lucky if it's fresh after a month.

Perhaps a week was not long enough. Maybe a month or more is what was needed?

I think you meant to say "if none of the beers are bad then this video is gonna suck." Cause we expect and want some of the beers to be bad.
Yes that's exactly what I meant!
