The collaborative beer was the work of five brewers - Sam Calagione (Dogfish), Tomme Arthur (The Lost Abbey), Adam Avery (Avery Brewing), Rob Todd (Allagash), and Vinnie Cirulzo (Russian River). The guys all took a trip to Belgium together a few years back and decided to make a beer together - this is it. The beer was brewed at Tomme's brewery and each company put in a few barrels of beer and some of their house yeast. The result is a tasty sour ale. The original label artwork was painstakingly painted by Sam Calagione.
