HI All,

I had planned on brewing this weekend but due to some other things I couldn't get time to do it. As I don't have a mill at home I buy my grains already crushed from the LHBS. Due to some travel plans I won't be able to brew and then complete a full ferment in the next few weeks so I'm wondering if I can store the cracked grains in the freezer until I'm ready to brew again?

Cheers

Bob

You definitely can. When I bought grains pre-crushed on a per-recipe basis, I used to freeze each bag for 72h to kill eggs from borers/weevils (all grain will have some amount of tiny eggs).

From a staling perspective, it probably doesn't matter too much (especially at this time of year), but I doubt it would hurt.

Surely the risk of moisture and the malt going slack in the freezer would outweigh the benefits of keeping it out for a few weeks?
