Beer!
Purple Haze followed by Amber (Mostly because you can find amber anywhere)
The seasonals are fairly good, and if the place is an easy run, you might want to go with the seasonals first and then come back and get the standards...since later on in the year you won't be able to get the specific seasonals. I think Strawberry is the current seasonal on the market, though it tastes like a kids cereal to me...too sweet.
