I'm Kat Melheim, aka: Roaster Kat, aka: Coffee Kat - roaster, barista, writer, artist, and founder/editor of Coffee People Zine (an art-based publication for the coffee community at coffeepeople.org).
Most of the videos on my channel so far are silly coffee-centric clips and coffee crawls, though I'm looking toward creating roasting content more and more. I started this channel in order to play with and practice filming and editing video - mostly to see if I enjoyed it, to find what I could learn, and to experiment with a new medium. It's fun to explore, and I intend to continue to make videos occasionally (maybe some day regularly) into the future!

Roastery Production Workflow Feat. SOVDA Precision Fill
This video was sponsored by SOVDA
In this video, we're looking at the production workflow at Black & White Coffee Roasters, featuring the SOVDA Precision Fill weigh and fill machines. The Precision Fill uses a 3-speed timer and choke system to weigh out the precise weight of coffee for any size bags. At Black & White, they have 100g, 12oz, 2lb, and 5lb bags.
In a high-volume production roastery, weighing and filling bags can be a main source of workflow slowdown and bottlenecking. A weigh and fill machine like the SOVDA Precision Fill can streamline the process and make workflow much more efficient. I have worked in places where I had to fill each bag by hand. And for small volumes that's absolutely fine. But when a roastery's output grows, filling bags manually can become too time- and labor-intensive, and other solutions need to be implemented.

Salute from a fellow former hand-bagger 🫡 great way to get weird arm and back cramps…
Great video! Respect to all coffee roasters, you are the unsung heroes! We love hearing your stories than you for sharing!
Just happened upon your channel, have subscribed and am looking forwards to more. Thank you.
11:03 RIP little fly
😬
P.S. My favorite B&W effort is always going to be a variation of The Future. I just love that funky stuff!
It's good funk, for sure ;)
90% of what I've learned in the last year about specialty coffee is thanks to Roaster Kat! Thanks Roaster Kat!
Aww, thank YOU for watching :)
Kat, any chance you could show your process of fulfilling an order, from receiving an order to roasting, to packing and shipping?
Next week's video will be the whole packaging line, so check back next Friday ;)
@@roasterkat Awesome! Thank you! ❤️
Neat but if all the beans are that consistent, wouldn't it sacrafice some complexity in the cup? Update : ah neat you did mention you can adjust how picky it is. Nice. Also was curious about how much coffee it would waste seeing the big pile! It looked like it threw out a lot but I'm guessing that bin hasn't been emptied after just one roast. Doesn't seem too bad if it's just like 1%
Yes, totally. If you want more complexity, you can leave a wider range. If you want clarity, you can narrow the range. And yeah, that bucket is about a week's worth of quakers - maybe more. On average I see about 1% of the coffee get kicked out, so it really isn't that much volume loss. Good questions, and looks like you answered it yourself :)
Thanks! A very interesting insight. What happen to all the "Bad" beans are they just composted or are they used for something else, making caffeine tablets for example?
Great question - at this point these are all put into the compost.
Hi from Raleigh! so cool to see all this cool stuff going on here
Hello neighbor! Thanks for watching :)
Very insightful. I didn't know this existed. Do you have an idea of the volume of quakers present in washed / natural coffees in like a 250g bag? If it's like 10%, I may be inclined to look for roasters that have this sort of equipment.
It really depends on the lots that roasters are buying. For the coffees Black & White purchases, I've seen <1%-3% get kicked out. Even in the Grade 2s and wild fermentations it would be 3-4% max for true specialty coffee. But even one or two quakers and impact your cup negatively (as you can tell by my taste test!)
Oh wow! I’m close to Nashville! Hello state neighbor lol. I’m excited to see you post again. I’m probably getting my first grinder and aeropress to make my first real cup of coffee this Christmas. I’m really excited to retire my Folgers tub 😅.
You will not be disappointed with Black & White. IMO, they’re the best in the business!
Awesome! Welcome to the wide world of Specialty Coffee. But be warned - there is no turning back when you start down this road. This Christmas it'll be a grinder and AeroPress and next year you'll be asking for a dual boiler espresso machine, WDT tools, and your life back ;P
They do a good job, for sure!

12:26 Do the dense beans really settle at the top? It's a bit counter intuitive because for example with fluids the more rense ones settle at the bottom. If they really do I wonder why that is.
Density dynamics work differently with solids than in liquids. Yes, the more dense beans go to the top. As the table jiggles the more dense beans move up the table and the less dense beans settle toward the bottom.
Love this!!!! How can someone get involved in coffee roasting/processing world???
Thanks! There are many avenues into coffee roasting and/or coffee processing - more than I can list here. I'd say start talking to local roasters and ask them questions, then go from there!
Culture vultures Ethiopia is the real place of the coffee pickers in the real elevation, higher elevation of coffee cherries fruit, show the real and not the duplicated. We are of a royal priesthood God's chosen ones the salt of the Earth.....
Starting with a known bbp is a very good start, I think. I think it was a coffee that lacked moisture, which is why it did not absorb heat at the beginning and the temperature rose at the end. It would have been helpful to measure moisture and density in green, to have an expectation of how it could behave and thus anticipate a probable behavior.
Totally agree RE: taking moisture and density readings. Unfortunately I didn't have that information so I had to go with what I had. But those are good points for sure.
The sugar content from the natural and washed during fermentation, is not the same right?
Sugar content of what - the mucilage/fermentation liquid, or the seeds themselves?
What yeast is used for fermentation?
Yeast is what makes fermentation happen. Yeast and bacteria eat sugars and make CO2 and alcohol. That is the process of fermentation.
@@roasterkatwhat is the brand/name of the yeast that you use for the anaerobic fermentation.
They do say you can pickle pretty much anything..
haha truth

How does the software know when the drying phase is complete and the first crack phase has fully begun? Which roastery is this also?
You can program the software to record those events at a specific temperature, or you can manually add them in. This is Black & White Roasters in Raleigh, NC
unless that phone app is absolutely 100% OPEN SOURCE it is guarnteed to be SPYWARE, there are exactly ***ZERO*** exceptions to this rule. You install that free application you turn yourself into the PRODUCT not the customer. I dont care if this is the worlds greatest home roasting system, because it requires the phone application it is absolutely BLACK LISTED by me and by anyone who wants to retain their privacy and security. Any input from the producer stating that "this app is not spyware" is a lie. If its closed source it is spyware.
That mask protects neither YOU nor the people around you, in fact it can harm you because your warm vapor filled breath encourages bacterial growth in the mask. throw that garbage away!
False. The mask protects your lungs from green coffee dust and roasted particulate that can cause allergies and respiratory issues long-term. Miss me with this nonsense.
Thank you for sharing knowledge📚 as a barista by profession I love ur video
Thanks so much!
I'm gonna need to pick up coffee roasting as a hobby to work on my neck mobility 🙌
😂join us!!!
You pressed it tho. Fail.
😂I knowwwwww whoops
Thanks for sharing maam kat,i would do it before roasting on 12hrs😅😅
🙌yes!
Thankyou . So good to see informed content. I own a little espresso bar. We have a roastry local owned by my business partner. The fluctuations are wild atm. We are having to chop and change single origins avaliable as the price is getting crazy. We are even having to play around with our main espresso blend as several components are out of control price wise.
On the floor we are seeing inconsistent brews sadly . While we try to get it right. Caturra is something we have to look into. I'll be bringing it up in our next meeting .
I'm assuming you are a green bean dealer?
Yeah things are wild right now!
🙌I’m a fan of Caturra personally! You can find really legit lots out there for sure
I’m not - I’m a roaster and content creator! But I do work for Algrano, which is a green coffee platform. If you’re looking to curate long-term relationships with farmers, that’s the place to be!
