"What's in your beer glass, Matt?"
Well, since you asked...
It's Sierra Nevada Porter.
Dark. Malty. Light flavor. No hint of hop aroma but good hop bittering, as the style dictates. Thick lacing from a creamy white foam head.
It contends with Anchor Porter for the title of best American porter, but I think that Sierra Nevada is a softer note, and more drinkable.
