Saison / Farmhouse Ale - http://beeradvocate.com/beer/style/129- BeerAdvocate
Victory is based in Downingtown, PA and the Victory Saison du BUFF comes in at 6.8% ABV.
Dogfish Head is based in Milton, DE and the Dogfish Head Saison du BUFF is also 6.8% ABV.
All of these were very good and were really tasty and it was easy to taste the herbs used in the brewing process. I would highly recommend that a taster pick up three bottles, one from each brewer, to sample and enjoy. This was a very good collaboration beer and the brewers came up with a great example of a special beer that is unique and is very good.
