We have some Wyeast Czech Pils yeast (2278) that was harvested last summer, mid July.
I decanted the liquid off the yeast cake. It did not taste good, with a very slight but noticeable off flavor. The yeast itself has a clean, and pleasant aroma.
Do we dare give this yeast a try? Or should we just dump it? It has been sitting in cold storage (38 F) all this time.
I am tempted to try it, but do not want to waste a brew day and 10 gallons of beer.
What would you do?
