How long is dry yeast viable if stored in a cool place?

I live in the rural North Georgia Mountains for two specific reasons... 1) to raise kids in a hopeful safer environment and 2) I don't want to be any where near Atlanta or other big city WHEN the SHTF! (This is whole other fun discussion for me).

So, I have a vault in the basement stocked with guns/ammo/food/survival crap.... for me, learning how to distill alcohol is simply acquiring another preparedness knowledge for SHTF/TEOTWAWKI.

Back to my yeast question... a lot of recipes here use simple old Fleschman's or Red Star baking yeast... Don't know about Red Star, but I believe Flechman's comes in small brown glass jars.

My vault is a cool 60 degrees year round... can I store jars of yeast indefinitely? Or do these suckers have an exp. date?

I heard that in Massachusset Bay, they found some old sunken ship from 200 years ago that had unopened bottles of beer and that from the sediment in the bottom of the bottles, they were able to grow and use the same yeast they used back then to make beer today that tastes like it did back 200 years ago.

Thanks,
M.

your yeast will keep for along time ,if not opened.once opened not so long as moister can deteriorate it.

I keep my Fleischmann's yeast at room temperature, sealed in it's foil bag with excess air removed, in a zip-lock bag, in a cardboard box, on a shelf... Never had a problem with it loosing efficiency... I go through between 2 - 4 pounds per year and buy it in 2 - 1 pound brick packages at a time... Room temperature is in the ~70F range year round...

I keep my distillers yeast as well as bakers yeast in the refrigerator. I use a vacuum sealer each time I use it, no problems so far.
