I am curious about how long is too long for yeast to sit in cold storage?
I brewed a batch of Nut Brown Ale and washed the yeast when I transferred it from Primary to the bottling bucket, placing the slurry into two separate canning jars. They have been in my fridge ever sense. (About 2.5 months)
A second question that I have is can you make a yeast starter with any container so long as it can be sanitized, and keep oxygen out?
I want to get a set of the Erlenmeyer Flasks but they are more expensive than I would like, are there any pros and cons to using say a 1 gallon carboy as the vessel to a starter rather than the flask?
Any comments would be greatly helpful!
