Dogfish Head Summer Seasonal: Festina Peche
Magnificently tart, crisp, and refreshing, fruity but not sweet; Festina Peche is a sour sipping beer.
It's seriously delicious.
(Sells in 4 pks. I found it at Whole Foods and at Raffe's in Memphis.)
For S&E and anyone else enamored by the exclusive-to-the-brewery-in-Ft.-Collins, La Folie, Festina Peche is the most similar brew to La Folie I've tasted.
