I saved the trub from an irish ale I brewed with the intent to wash it and save the yeast. Its been sitting in the fridge for almost 2 weeks, and I never got to it. Is it still worth it to try to wash and save? I plan on doing another red soon.. could I pour it back into the primary and re-use the whole thing? Or should I just toss it... It was Nottingham yeast that came in a brewers best kit..
