The (Kosmic Mother) Funk is Coming

KMF Grand Cru_504x504 LogoWe’re not releasing the Kraken, but it feels that way as we unleash one of our latest projects – the 2014 release of Samuel Adams Kosmic Mother Funk Grand Cru.

“KMF,” as we fondly refer to this beer, is a unique Belgian ale, brewed and fermented with multiple micro-organisms found in our historic 150-year old Boston Brewery.  The beer is then aged in Hungarian oak tuns in our Barrel Room for over a year.

Now, for the first time, we’re taking KMF on a mini coast-to-coast tour to share with drinkers like you starting this week in our hometown of Boston.

The Back Story

The inspiration behind Kosmic Mother Funk was Belgian beer, and the varied styles and brewing techniques like blending, aging and conditioning which yield wild and flavorful results. Our brewers began a few years ago by taking a Belgian ale and aging it in Hungarian oak tuns and as time went on the beer continued to evolve and take on a life and character of its own, only to be described as a kosmic collection of flavors. The porous character of the wood allows air to slowly seep into the beer during secondary fermentation, smoothing out any harsh flavors. Wild yeast and bacteria including Brettanomyces and Lactobacillus also interact with the aging brew, imparting unique spicy, fruity and bright tart flavors.  Long contact with the wood imparts its own flavors of oak and vanilla.  This resulting brew was so unique that the brewers started experimenting with blending the beer at varying levels into a series of Belgian brews, which ultimately became the Samuel Adams Barrel Room Collection.

For this ‘Grand Cru’ release, we added a touch of Belgian candi sugar to balance the beer’s tart acidity and lend a smoothness and sweetness to the finish.  The result is a wild, funky and complex ale, with a depth of flavors ranging from earthy and spicy to floral and sweet.
