I “happened” on a couple of opened 11 pound boxes of hops when I was looking at a closed down brew pub for a client. These were in boxes that are taped shut and the inner foil pouches seem to be rolled moderately tight. These appear to have been stored in a walk in cooler until the business closed about 6 months ago.
How do I figure out if these are any good and/or worth using? It is a lot of free hops but not worth ruining batches of beer over.
Also scored a unopened sack of Munich. Pretty sure that would be fine.
I might reserve them for bittering only. After you bitter 2-3 batches with them, you will be able to figure out the alpha acid content within 0.2-0.3% based on taste alone and then use that number with accuracy going forward.
