Next month, Stone Brewing Co., Dogfish Head Craft Brewery and Victory Brewing Co. are collaborating on a different version of a beer they first brewed together in 2010.

The beer is Royale Imperial Saison Du Buff, a 10 percent ABV “imperial farmhouse-style ale” brewed with locally-sourced lemon thyme, parsley, rosemary and sage before dry-hopping with Citra hops. The Buff in the name of both this and the original version, Saison du Buff (6.8 percent ABV) refers to an ad hoc coalition the three breweries formed in 2003 to draw attention to the craft beer revolution that was named Brewers United for Freedom of Flavor.

As the name suggests, this new ale is an imperialized version of Saison du Buff, a beer that was first brewed as a collaboration between all three breweries in 2010 at Stone before “ever-so-slightly tweaked” versions were replicated at each of the other two breweries later that same year. The saison was then rereleased by Stone in 2012, with Milton, Del.-based Dogfish Head releasing it again in 2014 and Downingtown, Pa.-based Victory releasing it in 2015. The latest release of the saison was earlier this year, when it was brewed by at Stone’s Escondido, Calif.-based brewery.

The new version of the saison is one of the brewery’s Groundbreaking Collaborations that is being brewed at Stone’s new Berlin facility, which opened in Sept. 2015 after more than a year of construction. In 2014, StoneBerlin launched an Indigo campaign online that eventually raised more than $2.5 million to build the new brewery, with contributors having the option of being awarded large-format bottles of 14 different collaboration beers that will be produced in the next year. However, smaller format bottles will be sold of some of the resulting collaborations. A post on Stone Berlin’s Indigo website indicates that the brew date for Royale Imperial Saison Du Buff is currently set for Sept. 20.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Royale Imperial Saison Du Buff will be packaged in 750ml bottles, although larger format bottles will also be available to the Indigo contributors. An email sent to the brewery for additional information was not immediately returned.
