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.

    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.

    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?

  • @joetilman7227

    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.
