The beer I try to always have on hand these days is Yards Philadelphia Pale Ale. It's a good "gateway beer" for anyone who comes over that drinks yellow fizzy macros, and it pairs well with just about anything, especially another. I'm also rarely without at least a sixer of Yuengling Lager, which is my go-to beer when I'm out at an unfamiliar bar -- almost any place around here will have Lager on draft, and if they don't, I'm probably in the wrong bar.

Other all-time favorites include the aforementioned Unibroue roster (especially Blanche de Chambly and Fin du Monde), just about anything from Troeg's, especially Dead Reckoning Porter, Franziskaner Hefe-Weiss, Weihenstephaner Hefe-Weiss, Allagash White, Dogfish Head 60 and 90 Minute IPA, Victory Storm King, Magic Hat #9, Stone Ruination IPA, Bell's Two-Hearted Ale... those are all definitely in the top tier.
