Top 5, in no particular order:
1: McMenamin's Ruby Ale (or maybe anything else from the McMenamin's breweries. PacNWers will know!)
2. Guinness, preferably on tap.
3. Bass ale, by itself. Also the best for parboiling bratwurst in (w. onions) before grilling!
4. Fat Tire (hey, I was a mountain biker first...)
5. Hair of the Dog; Fred. An Oregon micro, pricey, rare, about 12% alcohol and thick as hell, but DEEE-LISH!
