The collaboration brew, called Funk Vessel, will be available only in 22-ounce bottles in Ohio, Kentucky, Indiana, Tennessee and Florida. Both Rivertown and New Holland used the same recipe to brew the beer at their respective breweries and then "each brewery swapped sour barrels," Rivertown brewer and co-owner Jason Roeper said in an email.
New Holland used Rivertown's 2011 Geuze barrels, and Rivertown used New Holland's 2012 Blue Sunday barrels.
"The end result is a one-of-a-kind, out-of-this-world, mouth puckering experience," Roeper said.
The New Holland version is set for release in February.
Meanwhile, Rivertown will release Ville De Rivere Geuze (a blend of 2010, 2012 and 2013) in 22-ounce bottles. It also will be available at craft beer stores in Ohio, Kentucky, Indiana, Tennessee and Florida.
