Hi,

I finally received a pound pack of EC-1118. It has an expiry date of Oct. 2018, so I now have lots of yeast to make good wine with. What I am worried about is how to preserve so much yeast for such a long time once the packet is opened. Hope some of you can tell me how I should do it. Should I refrigerate it, or put the packet in the freezer?

Thanks!

I keep mine in the freezer (not the fridge that defrosts). I've always kept the bread yeast that way. I have 8 yr old bread yeast that works every time.

Vacuum pack what is left and into the freezer. That's what I do. Haven't done a comparative test, but it works for me. Logic is that is how I get it. Of course I have a vacuum bagger and freezer:sl
