Simple question. I just want to know how long my washed yeast will keep in the fridge before I have to re-culture. It's probably been in the fridge for at least 8 weeks.
I've used yeast up to about 3 months old with success. If it starts to get dark toss it. Take it out an make a starter, if it doesn't smell yeasty/bready/biscuity i'd toss it. Not worth risking a batch unless you are pretty confident. Learned that the hard way!
Lots of posts about this already. Most say up to a year with no problems. Some have used after a year with no problems. Use common sense, if you open it and it stinks, dont use it. Otherwise get a starter rolling.
