Uses
Primary
- Production of ethanol and carbon dioxide via fermentation.
Secondary
- Leavening bread
Cultivation
- Grind 1/2L of grain very fine
- Mix it into 2L of water
- Place the mixture in a well-washed well-rinsed clean bowl with a wide brim
- If possible, place a screen or fine-woven mat over the pot in place of a lid. It would let the air flow in freely, but not bugs.
- Wait one day
Check: If the solution is not fizzing (carbonated, small bubbles rising from within) discard it and repeat from the beginning. - Discard any foam on top of the water
