Hey everyone,
I like to store my yeast in pint-sized mason jars. I usually brew with vigorous top-croppers, and find pint jars work well for storing enough yeast to direct pitch next brew day. I always harvest, let the yeast settle, then top up top the brim with cooled, boiled distilled water.
I used a new yeast strain last weekend (WY 3711), made an over-sized starter and stored about 70 ml of it (finger width) in a pint jar under a half pint of the spent starter wort. The jar is half filled basically.
I've never done this before and I'm wondering if I should fill the jar to the top as per usual. Are there any risks to storing yeast in half filled jars for extended periods?
