Using Batch Size to Control the Roast (Shelby Williamson of Huckleberry Roasters) Roaster Kat 2023-09-05 | Hey coffee roasters - do you ever wonder how much coffee to put into your machine? If so, this video is for you. It's the first video in a 4-part series about batch size for coffee roasters. I wrote an article about batch size for Roast Magazine’s September/October 2023 issue, and these interviews were research for that article.In this first video, I interview Shelby Williamson (2019 US Roasting Champion and head roaster at Huckleberry Roasters in Denver, CO). Shelby roasts on two machines - a 15kg Giesen and a 70kg Loring roaster. I love this interview because she’s a working roaster and talks about the practicalities about batch size as it pertains to production roasting, rather than getting in the weeds about theory. Shelby gives key insights into batch size, including adjusting roast weight as a way to control roast time (aka: hitting her marks), determining batch size based on inventory management needs (ie: basing batch sizes on bag weights), and much more.Like, comment, subscribe, and hit that notification bell for more coffee roasting content.Other Videos in this Series:Part 2 w/ Scott Rao of Prodigal Coffee: youtu.be/B3kxtZanANYPart 3 w/ Cameron Heath of Counter Culture: youtu.be/QXtuAEURqFQPart 4 w/ Bill Kennedy of The San Franciscan Roasting Company: youtu.be/xxzw3Dls5l0Thanks for watching!Roaster Kat

Coffee Processing: Lactic Process Washed Fermentation EXPLAINED (w/ Lucia Solis) Roaster Kat 2024-03-02 | 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: youtu.be/QlxmEc4zf14?si=aMgTeS_zXWBoGOSe1:10 Floating and Sorting Coffee Cherries2:07 Pulping the Coffee2:59 Lactic Process Explanation6:01 Lactic Process Demo8:19 Fermentation Time: 6 Hours9:16 Fermentation Time: 20 Hours9:29 Fermentation Time: 44 Hours9:47 Fermentation Time: 68 Hours10:00 Washing and Drying CoffeeNote: This video is descriptive of what we did, not prescriptive or intended as a guide.

Coffee Processing: Yeast Inoculated Washed Coffee Fermentation EXPLAINED (w/ Lucia Solis) Roaster Kat 2024-02-17 | TLDR: This video shows the entire process of a small batch of yeast innoculated coffee. Filmed at Lucia Solis' Fermentation Training Camp in Colombia, January 2023. Descriptive, not prescriptive.Yeast innoculated coffee processing... what does that mean? On a basic level, it is utilizing yeast and bacteria in coffee fermentation to go from coffee cherry to dry coffee parchment (which a producer can sell or further process). It can allow a producer to conserve water, as well as get consistent results batch to batch and/or year to year. I learned all about this process in a week-long Fermentation Training Camp run by Lucia Solis. Lucia comes from the wine world, but switched gears and became a coffee processing specialist. She works with coffee producers around the world to create efficient systems, streamline their processing, and create consistency in their coffees. She is also the producer of "Making Coffee with Lucia Solis," a podcast I highly recommend if you're curious about coffee processing and fermentation (linked below).In this video I show you each part of the YEAST INNOCULATION process we did during the camp - from receiving the coffee cherries, pulping the coffee, the 3-day fermentation, and drying the coffee. Timestamps below.We did two other processes - CITRIC and LACTIC. I will be uploading those videos in the near future, so subscribe and keep and eye out for those!01:51 Receiving and Floating Coffee Cherries03:22 Maturity Table05:15 Brix Measurement06:00 Pulping the Coffee06:48 Yeast Explanation & Demo10:58 Fermentation Time: 1 Hour11:52 Fermentation Time: 6 Hours12:29 Fermentation Time: 22 Hours13:19 Fermentation Time: 24 Hours13:39 Fermentation Time: 46 Hours14:54 Washing and Drying CoffeeNote: This video is descriptive of what we did, not prescriptive or intended as a guide.

The Physics of Heat Transfer and Artistry of Batch Size (Bill Kennedy of San Franciscan Roasting Co) Roaster Kat 2023-09-26 | The last video in this 4-part series about batch sizes for coffee roasters. These interviews were done as research for Roast Magazine's September/October 2023 issue.In this video I talk with Bill Kennedy, owner of the San Franciscan Roasting Company. Bill comes from the manufacturing side, as well as being an experienced roaster himself. This interview is the most technical and physics-heavy, but Bill has the ability to break complex concepts down into easily understandable ideas and practical applications. The main takeaways I got from this interview include finding a batch size that allows you to achieve the roast profile you want (curve shape, roast time, etc), an explanation of the physics behind convective and conductive heat transfer, roast consistency and heat diffusion (especially based on roasting drum material), and so much more.Put your favorite takeaway below, or commend any questions you still have.Like, subscribe, and hit the notification bell - you'll be the first to know the next time I drop a video.Also I'd love to know if you liked this series of interviews, and if you want to see more content like this.

Roasting EA Sugarcane Decaf Coffee from Colombia (on the Loring S35 roaster) Roaster Kat 2023-08-15 | Forget death before decaf - decaf coffee is amazing! Or it can be anyway.In this video I'm roasting a big batch of decaf coffee. It is an EA (or ethyl acetate) decaf, also known as Sugarcane Decaf. Ethyl Acetate is made from a natural byproduct of sugar production. Coffee is placed in water, then ethyl acetate is circulated throughout, and it naturally binds to the caffeine molecules and pulls them out, leaving behind all the tasty stuff. It's the best decaf I have had the pleasure to drink (or roast)!The goal is to get enough development to mitigate any "decaf" flavors (can be grassy, medicinal, chemically) but still light enough to preserve the intrinsically delicious flavors of these beans.It's a 66lb batch on the 35kg Loring roaster, which isn't the largest batch size I do but is a larger batch than I usually roast.*NOTE: This video is relatively advanced, assuming previous knowledge of coffee roasting language and concepts. If you're a coffee roaster, I hope this video will be interesting or useful to you. If you are not a coffee roaster, well, I'm sorry if it's confusing or boring.Questions or comments about decaf?
