If you are making a wild yeast for (beer) brewing, be sure to start it about a week before you brew your beer.
- Combine 1 part sugar to 4 parts (de-chlorinated) water. I like to use unpasteurized honey as it contains a lot of yeast.
- Add some yeasty ingredients such as berries, flowers, leaves, bark—whatever you can find around your yard or kitchen.
- Cover with a cheesecloth and put in a warm place. Stir at least 2-4 times a day until it becomes active.
- After 2-5 days, bubbles and foam will appear at the top of your jar. Active fermentation has begun.
