In the video below, we will show you how to make an anaerobic fermentation tank for coffee fermentation. Anaerobic fermentation is a process of fermenting coffee beans in an oxygen-free environment. This can be done by using a sealed container, such as a barrel or a plastic bin. To make an anaerobic fermentation tank, you will need the following materials:
- A sealed container with a watertight lid (Techpack 210 in this video)
- A one-way valve (air lock)
- 12mm grommet
- Tap (Optional)
- Drill with 24mm Step bit and 10mm bit
