My bottle of Sierra Nevada’s Hoptimum is probably old, probably really old. I don’t feel like figuring out the mathematical jargon on the neck, but this beer has probably been on the shelf for a while. It started out like a proper double IPA, juicy and sweet — toffee, orange, and caramel. But this bottle quickly turned barleywine on me. Suddenly, my Hoptimum became a Bigfoot — bitter and dry, earthy and piney. I guess that’s what happens with ten percent beers with a little time. I’m not complaining; it’s still interesting.
