Subject: shelf life of crushed grains
|
i purchased some grains from my LHBS the other day and crushed them,
thinking i would be brewing within a day or two. however, i was unable
to get to the brewing as quickly as i had assumed, and am left
wondering how long grains that are crushed retain their freshness. a
week? two weeks? longer? does it depend on the type of grain? (in this
case i am only using specialty grains.) would it help to store them in
the fridge?
thanks.

The best way to store them is dry and airtight. In or out of the fridge
doesn't make much difference.
Crushed grains, if stored well (see above), can generally last for several
months. Uncrushed grains, if stored well, can last for years. IMO, a
couple weeks is no big deal.

Does vacuum sealed help more? I bought 5# of crsuhed crystal that I was
thinking of breaking up into 5 x 1# vac-sealed units..

A friend of mine uses those large bags you use to store things like
winter clothing - you see them on TV where they fill it full of bedding
and stuff and then attach a vacuum to squish it down to a much smaller
size. He stores his unmilled base malts in them. Couldn't tell you if
it works any better/worse than other methods, but I thought it was a
nice way to vacuum pack a large amount of grain.

I asked this of my LHBS last week. He put it in perspective of a
couple of local brewbups that get their grain crushed. Hewas pretty
sure that they do not have " just in time" inventory deliveries.
Bottom line... we think 6 weeks is no big deal.

I think it would be far to great. But you could just leave it in the
grain bag it came in and fold the top over. It would still evacuate all
the air out. Also, since it's a vacuum cleaner, it wouldn't be damaging
for some grain to get sucked in.
