I feel like there needs to be some limit of some sort...else I'd just have all the beers...
Before I write a list I'm going to self-limit myself to one establishment, with two bars, each bar having 5 taps.
Bar 1 - Social beers
Best Bitter (cask)
Bar 2 - Specialty beers
Rauchbier (Schlenkerla on cask?)
Imperial Stout (cask)
Belgian seasonal tap (Saison, Dubbel/trippel for Lent/Easter, Golden Strong ale, etc.)
Other seasonal tap (Maibock in spring, Hefeweizen in the summer, American Brown Ale in the fall, etc.)
