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!
Thanks for watching, thanks for subscribing.
Please get in touch if you have questions, comments, or ideas for future videos.

Coffee Processing: Lactic Process Washed Fermentation EXPLAINED (w/ Lucia Solis)
This video shows a Lactic Process washed fermentation. It's the third (and final) video in this coffee fermentation series, showing processing techniques I learned about at a week-long Fermentation Training Camp hosted by Lucia Solis in January of 2023.
The first video about Yeast Inoculation lays a good foundation for understanding what happens in this video, so if you haven't seen it - watch it here first: th-cam.com/video/QlxmEc4zf14/w-d-xo.htmlsi=aMgTeS_zXWBoGOSe
1:10 Floating and Sorting Coffee Cherries
2:07 Pulping the Coffee
2:59 Lactic Process Explanation
6:01 Lactic Process Demo
8:19 Fermentation Time: 6 Hours
9:16 Fermentation Time: 20 Hours
9:29 Fermentation Time: 44 Hours
9:47 Fermentation Time: 68 Hours
10:00 Washing and Drying Coffee
Note: This video is descriptive of what we did, not prescriptive or intended as a guide. There was way more than I can accurately cover in a short TH-cam video, so if you want to learn these processes in more detail, I recommend attending Lucia Solis’ Fermentation Training Camp yourself. AND listening to her podcast.

This is a day in the life of a production coffee roaster. From a 7am start to wrapping up early at 3:30pm, this video takes you through a more-or-less typical Monday at Black & White Coffee Roasters in Raleigh, North Carolina. Every day is a little bit different depending on the roasting needs, shipping volume, and other projects, but you get the idea. Today I'm on the 15kg Loring roaster, whic...

These videos on coffee processing have been crazy informative and super interesting. I’ve been looking for a breakdown on all the different processing methods and these videos have absolutely nailed it. Tons of info that was well explained without feeling overwhelmed.
In my job, we only say "¿se lo tiro?" (Do I throw it?) Haha.
Hi dear where have u been hope you are fine. no update from last 5 months to be honest loved your coffee knowledge videos please share more
So what was the use of the yeast I thought you were going to show us its effect like on taste.
Can you come to my dads coffee/boba cafe/shop it’s aloha tea and coffee :D
Indonesian pre wet hulled process (stored within its parchment) would avoid the beans from fungal infection, but it risks the beans being damaged during hulling the parchment.
Understood 😃
I am from Kodagu, India. I have coffee plantations. Here we don't use any sort of yeast. We directly dry it , what is the point of using yeast and fermenting it?
Haha That's was awesome ❤😂
Don’t know who your boss is but you deserve a raise
Aww thank you so much! I’ll tell him😉
Hi, where will the coffee not roasted properly go after that color-sorting part? What will you guys do with it?
It is thrown in the compost.
Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 ✌ ☮ ❤ 🕊

Hi Kat can I get ur email address please
By definition, all fermentation are anaerobics. This is redundant
You got it! Been listening to Lucia Solis, have you?
@@roasterkat Yes I have! And your video was really helpful by showing the submerged fermentation that Lucia loves so much 😂 This is awesome
I would love to know how to roast at home if possible?
I haven’t roasted at home myself, but I know there are a number of accounts out there with tutorials and how-tos.
I really love your videos
Thanks so much!❤️🔥
I get it now!
💯🙌that’s the goal!
I have recently decided to switch to coffee career. And your channel has become my inspiration. ❤❤❤
Wow, that’s awesome! Good luck and welcome to the wide world of coffee❤️🔥
@@roasterkat Thank you so much
What is the name of the lady that the man carries and collects coffee beans in it I want to order it from Amzoum
?
This video was 110%
Thanks so much! Bill knows his stuff that’s for sure.
What kind of yeast do you use?
They didn’t tell me - it was a secret!
Wow, amazing content! I'm also a big fan of natural anerobic fermented beans.
Awesome! Thanks so much. Glad you enjoyed the video, and those coffees!
What kind of yeast is it?
Not sure, they didn’t tell me and I didn’t know much about fermentation at that time.
I just roasted some Honduran beans a couple weeks ago. They were so long. Kinda like footballs great coffee. Thank you for your videos
🙌🏈❤️🔥
da ngeen con torop koulen ko deflo niii ? lolen guiss yaak ko! waay wuuu way
8:15 the girl in the be hating on the girl speaking. Hmm wonder what the drama is there??? Or maybe it is just hot😂
😂it was very hot! She was also working at the workshop so she had heard that speech many times before haha
How'd it turn out?
Great! It was a while ago now but I think it was tasty🙌
Thank you for sharing the FTC information. I’ve been listening the podcasts by Lucia from early 2020, and the camps have been a distant inaccessible information…so your shares help to relate more with what I’ve been hearing these years through her podcasts. I wonder how I missed this in the Discord forum… you haven’t shared the links there ?
Awesome! Happy to add more context. I’m not on the Discord. I love Lucia’s podcast but I’m not a Patreon supporter. Maybe I should become one! You inspired me😉
Hi guys if you need supply for some delicious coffee beans Just contact me and make a conversation
Please make sure you wear hearing protection. Noise induced hearing loss is increasing.
Thanks for the tip! Are you seeing that a lot in coffee roasters?
also, on the loring what do you set your air cool on and does change with every roast or do you have a base line temp and time?
We don’t use the Air Cool function where I work.
hi there, do you charge when the bean temp is correct or the return air is correct?
With the Loring machine we use return air
How often is it recommended to clean the clycone?
What are you looking for and smelling for when you are pulling out a sample around first crack?
Smelling: a change in the smell, visually: the release of vapor or the beans moving slightly to indicate first crack
As a coffee nerd and lover I always loved the process of roasting and making the fresh coffee but seeing this video made me very curious about making instant coffee. I would love to work like Dan, at that atmosphere with the smell of beans and the coffee that's brewing.
It’s a special job that’s for sure!
Thank you for your information about coffee, I'm barista but I did not know different between washed and natural 🤔❤
Now you know! Thanks for watching!
You should really have ear protection, I run similar machines on a larger scale , and it's not healthy. Like your video's though keep it up!
Thanks much - that’s a good tip for sure.
Well, recently came across this bug in my coffee plantation. Didn't know its extensive damage on coffee productivity and quality. I have managed to control the bug 🐛 and looking forward to some promising crop.
🙌❤️🔥
I've seen this video numerous times and still pick new things! Thanks for sharing.
That’s awesome! So glad you enjoy it. Thanks for watching!
cool video, which brand is that green jumpsuit ?
Dickies🙌
Please provide us the contact details thanks
the mad-scientist science is blowing my mind and i very much appreciate seeing a nerd that truly knows and loves his subject
It’s above my head but I’m glad Dan gets it😅
I dip the outside edge of the spoon when filling the spoon so the edge that touches my lip stays away from the coffee as much as possible. It’s still not perfect, but I’m just cupping with friends anyways
😂I doubt that really stops the spread of germs at all. Might as well just do pre-Covid protocol at that point imho
This is so good!
😂❤️🔥
Did this curve come with a charge temp you followed or did you choose one based on experience with this size batch and roast level?
I used one that was typical for that batch size and desired end temp
Thanks for sharing. I’ve been home roasting on a Bullet for almost 3 years. My friends and coworkers are requesting coffee more and more, so I’m starting to get curious about someday starting a small coffee business. Unfortunately, my job has me moving every few years, so I haven’t been able to start an apprenticeship with an established roaster. Besides frequent and deliberate cupping, do you have any tips for helping me refine my skills as a roaster without a community of professionals to help me grow?
Do different decaf processes roast different? Don't the SW and MW processes use higher temps than EA (I may have that backwards), thus providing effectively parboiled coffee? And I would imagine CO2 process having even greater differences.
This series is great! Thanks for putting this all together.
