+googolplex on this tip!!! I just opened some Centennial (supposedly 2008 but they're a much paler color than my 2008 Cascade) from Freshops and they smell like a 50/50 mix of citrus and cheese. Smelled so bad I was considering throwing them away and not tainting malt with them. After a few minutes soaking in hot (microwaved to around 140F) water, a single cone smells like a nice herbal tea and tastes nice and bitter without any cheese/feet flavor/aroma.Drop a teaspoon (if their whole hops) or a couple pellets into a cup of your hottest tap water and let them steep a few minutes. Then give em a whiff.
Dried hops rarely smell "up to their potential".
