I've seen multiple posts that expired yeast can still be good past its expiration date, but not too many on how the yeast should taste and smell.
What should healthy yeast smell and taste like, and how to know if its gone bad?
I have 2 packages of the white labs purepitch yeast, packaged mar 2017 & best before sept 2017. I'll be brewing with this yeast mar 2018 (26% viable cells - so I pitched 2 packages with a a 1L starter). When I opened the yeast, it looked like any other liquid yeast, smelt ok but sort of had a sour taste. Is this normal for liquid yeast (I've never actually tasted liquid yeast before, so not sure if this is typical.
I'm wondering if its worth pitching this yeast starter or buying new liquid yeast packages?
