Question. I often order my crushed grain from Austin Homebrew because they allow you to order small amounts and will put it together as seperate grain bills in sealed bags.
I ordered a grain bill for an amber ale a few months ago thats been sealed at basement temp out of the light. I'm wondering if I should go ahead and brew it now? It's mostly two-row with some crystal and flaked wheat. Maybe add a pound of two of extra two-row in case of low conversion?
I have brewed with 2 month old crushed grain, sealed, and in my keezer at 34*F and the beer came out great, like it was only crushed a couple hours ago. I dont know what your basement temp is but I bet the grain is still in pretty good shape.
Moisture is the big spoiler for grain. My LHBS mills into paper bags but will use resealable plastic upon request. I do paper and plastic. When I get home, the bags go into a sealed bucket until brew dayas an added precaution. We bought a bag of bird seed once that was loaded with weevils. Finally got them eradicated. Still gonna use the bucket just in case.
