At this point I’m pretty sure there must have been some sort of storage issue with the bottles I had: they were too old, or stored warm, or something. I’m willing to give Siletz Brewing the benefit of the doubt and should I get the chance, I’ll visit the brewery and try their beers on tap (and presumably fresh and problem free!).
Too bad, though. Even though there are only four reviews of this one so far on BeerAdvocate, they’re all positive. Same deal on RateBeer (scored in the 89th percentile). Jeez, I’m starting to feel ripped!
