(Boulder, CO) – Expanding their one-and-done series of experimental barrel-aged beers, Avery Brewing Company sets the date to release Oud Floris, a sour brown ale blended from thirteen wine and liquor barrels. At a very limited release of 252 cases, the brew spent between 1-3 years maturing in 13 different barrels, and presents what the brewers describe as a “Flanders-esque” flavor profile, both sweet and sour with notes of fruitiness.
