I have a 25kg sack of crushed Maris otter that's been sitting in the spare room since July that I really need to use up. I have a. American IPA, double IPA and imperial stout planned which should get through a fair bit !
I'm a little concerned that the efficiency will be a lot lower than expected as it was crushed quite a while back.
Should I increase mash time, add a little extra to the recipe or just wait and see what happens ?
Crushed malt efficiency
Re: Crushed malt efficiency
I don't think you should have a problem if the grain has been kept sealed and dry. I would make the first brew as normal and then adjust your later recipes if there's a marked loss of efficiency.
Re: Crushed malt efficiency
Yup it's all sealed up in the dry, I've read that anything up to 6 months if you buy pre crushed but some off the other malts I have state up to a year on the bag
Il give the IPA a bash this weekend and see how it works out

Re: Crushed malt efficiency
The crushed malt I buy from the Malt Miller has a best before date of 1 year. Never noticed any loss of efficiency when I'm at the end of a bag which can be 6 months after I buy it.
