"Yeast boot camp" selects for Saccharomyces strains that are easy to use, but has a low rate of success (around 5%) finding strains that ferment well and taste good.

1. Create 75mL 6°P wort with nutrient (0.25-1g/L) in 250mL Erlenmeyer flask.
2. Inoculate with anything from your environment.
3. Add foam stopper.
4. Allow to ferment with continuous stirring on a stir plate (24-48 hour). 80-90°F. Add airlock when foam is visible.
5. Decant and pitch into 8-10°P wort plus nutrient, stir plate, anaerobic, until competition.
6. Decant and pitch into 20°P wort plus nutrient, stir plate, anaerobic, until completion.
7. Streak and isolate.
