My LHBS gave me a pound of 2007 Magnum leaf hops, free. They are still in the original 2-oz vacuum sealed Brewcraft bags. No air leaks. I opened one and it was very pungent and fresh smelling. How far off will the AAUS be at this date in time?
Plug the AA into ProMash or BeerSmith’s hop age tabs to get the bittering potential. Hop Union lists this variety as “very good” storageability. Using 13 AA, 40 months of vacuum seal, refer temp, ProMash says 8.23 AA, BeerSmith says 9.98 AA.
I buy bulk, vacuum seal, freeze and as long as I adjust for hop age, I get easily a couple of years worth of use. I do notice a small amount of aroma loss on the oldest though so I try to use up aroma hops first.
How were they stored? Fridge or freezer?
