*5-1/2 Year Old Yeast*

We have a refrigerator in the garage that keeps an almost constant temperature of 38 degrees. It is on a GFCI breaker connected to both bathrooms, and occasionally will get tripped when my wife and daughter are using hair dryers, curling irons, etc. The breaker is really hard to reset, so they just wait till I get home to tell me about it. By then the temperature has risen to the mid 40's before I reset the breaker.

Back in September 2014 I bought some packets of yeast and put them in a baggy in the back of the refrigerator. I told (ask) my wife not to use those packets for any reason. I wanted to see how long it would last, and still be good. If she needed some packets of yeast, I would go get some.

She bakes bread pretty regular, and last week we decided to use one of the old expired yeast packets to see if it was still good. The bread turned out great. This week she baked more bread using the old expired yeast packet to see if the first batch was just a fluke. This last batch is just as good as the ones she baked last week, and just as good as using unexpired yeast packet. The bread rose both times just like it was supposed to.

To be honest, I have been thinking about throwing these packets of yeast away since it was 5-1/2 years past its expiration date, and starting over. I am really glad I didn't. We wouldn't have known that the yeast lasted so long.

We also have a few jars of yeast granules that I was anxious for her to try with about the same expiration date. I just opened both of the jars and the lids popped like it was supposed to, but the yeast was dark gray. Both bottles were no good.
