....... thanks for both of your replies.
You said you're keeping it for several month in the fridge, I have some EC-1118 in there for about 2 years but these are aluminum vacuum packs.
They are still ok, even though I've got the feeling that the yeast is going a little weaker now.
I'm expecting a big pack in the near future and I'm worried that after opening the vacuum pack that it wont last as long as the sealed packs.
Would diverting into several zip-lock bags be good enough ?
Thanks again for your help .......
