I have some washed Vermont yeast from my last two brews. 1 in early nov and 1 in early dec. how long should I keep them before they need to be used up by?
How are you storing it? Several months in the fridge is the general advice from the likes of beersmith, but I wouldn't go over 2-3 personally. And I wouldn't use it more than 4/5 times or you run the risk of wild yeast / bacteria creeping in.
They are both in sealed jars in the fridge. I kept the first jar as backup in case on brew day I discovered the second jar was infected.
Open them and if they smell fine then they should be OK to use. They are not that old.
Perfect thanks
