Beer is typically fermented in a very calculated, controlled manner with pure strains of brewers’ yeast. Our blackberry lambic beer is instead fermented by exposing it to the untamed yeasts and bacteria that are native to our Brewery. We affectionately call this unrestrained, wild amalgamation our House Funk. This blend is unique to Rivertown and this unusual, spontaneous process, involving over a year of fermentation in oak wine barrels and over 45 pounds of fresh, whole blackberries per barrel, is what gives this beer its distinctive flavor; semi-sweet, funky and vinous with a crisp, tart aftertaste that will continue to develop in the bottle for years to come.
