How much AA% do my hops lose in the freezer?

NitrouStang96 · Feb 28, 2008

I don't have them vacuum sealed or anything - just different types of pellets in the plastic bags from the LHBS all together in one big ziploc. Just wondering if I should recalculate the IBU from a lower AA% after a few months to half a year.

Not if they're frozen, the loss rate is minor.

So when Beersmith says Tettnang loses 40% AA% in 6 months, is that if left out in the open or in the freezer?

That's at 20˚C.
