I'm looking to use up some pellet hops I bought last year in 2 batches. Some are sealed in barrier bags, some are vacuum sealed, and some have been opened, sealed tight with tape. All have been in my freezer double ziplocked since I've bought them. I sat down this weekend and reformulated my recipes
to use most of what I had using the "hop age" tool on Beersmith. Not knowing when these things were harvested, I figured the "months" from November 2010. Is this the correct way to figure this and to those who have used this tool, how accurate is it at refiguring the A.A's?
