I decided to hold onto the Kellerwies yeast until I do a German style wheat. I have a half inch to 3/4" of beautifuly creamy beige yeast on the bottom of the jar.
Since i had some saved Wyeast 1010, I pulled that out of the fridge last night and made a starter from it. It went nuts. About 100 ml worth of foam overflowed from the flask, but since I overfilled it a bit, I have just a little under 1L to work with on Saturday.
Yeast farming is almost as fun as brewing itself.
