Petri Dishes, Bag of 25

Bag of 25 sterile petri dishes in packaging for making yeast culture plates. Tired of seasonal yeast's not being available when you are ready to brew? Find a really great beer that you just can't clone? Yeast culturing is the way to go. These petri dishes will help you culture your own yeast for later use. May not be used in a pressure cooker.

If taking the yeast from a commercial beer it must be unfiltered and unpasteurized to be able to culture.
