How long can you use expired yeast?
« on: February 26, 2009, 03:35:45 PM »
I was making some dough the other day and checked the expiration date on the instant yeast.  It was April of 2007.   :-[ I've been using it all along and it seems fine and I should mention that I keep it in the freezer.  I went to Sam's today and got another 2 lbs with an expiration in 2010, I'll just toss the expired stuff.  -RP

Buying a new bag of yeast at the price that Sam's charges makes it economically palatable to discard old yeast. But, like you, I keep my dry yeast (SAF Red IDY) in the freezer and, at the rate I use it, it can last for several years. I often compensate for the aging of the yeast by simply adding a small pinch more to the amounts called for in the dough recipes I am using. Some of those recipes have called for as little as 1/64 teaspoon, yet that amount worked without any problem despite its age and even without increasing it.
