Growing yeast from a plate (petri dish) allows the brewer to select only a few single cell growth colonies. By doing so a pure culture can be obtained even if the starting culture was questionable. But because the number of yeast cells is very small during the first few steps, a sterile environment is necessary.
What is needed?
- petri dish with yeast colonies (Yeast Cultures on Petri Dishes)
- inoculation loop
- flame source. Bunsen burner, alcohol lamp, blow torch or gas stove
- vial with sterile starter wort
