Cleaning up some brewing stuff last night - found two 1-oz packs of 8.7% AA Centennial pellets that somehow escaped the brew pot.
They're still vac-sealed in their original "nitrogen-flushed" packaging. They've been at room temperature.
Based on other stuff in the box (the bags don't have any date markings at all), I estimate they've been laying around for about 18 months.
Any thoughts about using these guys after all this time? What is the "shelf life" of a vac-sealed hop pack at room temp?
