Got an issue I need to talk through. Your advice is encouraged.
A few months ago I used some SafeAle-05 to make a real good pale ale. I washed the yeast and put it up in mason jars in the fridge.
I have made two beers with the saved yeast since then. They have both tasted like bananas!!
I ferment my beer in stainless steel inside a fermentation cooler, so I can't imagine that the esters are picked up from high temps. And I have made a few ales with exactly the same equipment in the same timeframe from other yeasts that have turned out well.
Anyone ever heard of a contamination leading to Banana flavor? Am I missing some other way to pick up this flavor? Would you toss all your saved yeast and start fresh?
What is the best way to isolate my issue. I am thinking about using some LME and make up few one gallon batches (in old cider jars) to try to see if I get the banana flavor out of the questioned yeast..
Very frustrating to have a good beer go bad!!
