Brand New Limited Release Brings the Funk for Fall


PRESS RELEASE / August 19, 2019 (Boston, MA) – Samuel Adams Kosmic Sour is a tart and wild ale that’s light-bodied and crisp with subtle cereal notes. It’s a dark golden beer that offers complex flavors including strong red fruit notes upfront, balanced by sour and sweet pale malts.

Kosmic Sour is blended with a funky Belgian beer called Kosmic Mother Funk (KMF)®, an ale with spontaneous fermentation that’s been aged for two years in Hungarian oak barrels called foeders. Wild yeasts in these barrels impart a unique, fruity, funky character on the beer for a slightly tart and mostly dry finish.

Through the extensive research and development of Kosmic Sour, multiple variations of this beer have been featured in our Boston Brewery Tap Room where it consistently ranks in the top five of weekly sales. Based on this success and the growth of the style, we’re thrilled to expand the offering nationwide for the first time ever with this seasonal limited release.

Pairing with Food: Kosmic Sour complements both sweet and savory flavors with its complex fruity and tart character. Pair it with marinated meats such as chicken or flank steak, or even a bitter arugula salad topped with grilled chicken, where the funky notes of Kosmic Sour will add a layer of depth to the dish. For a twist, try Kosmic Sour with a salted caramel chocolate torte.

Pricing & Availability: Samuel Adams Kosmic Sour is available nationwide from August through October in 6-packs for SRP of $9.99, 12-packs (bottles and cans) for SRP of $17.99 and on draft. Also available in the Samuel Adams Fall Variety 12-pack and Samuel Adams Fall Can Variety Pack for SRP of $17.99 and 24-packs for SRP of $29.99. Price for each package varies by market.

About Samuel Adams

Samuel Adams is a leading independent, American craft brewer that helped to launch the craft beer revolution.  The brewery began in 1984 when Founder and Brewer Jim Koch used a generations-old family recipe to brew beer in his kitchen. Inspired and unafraid to challenge conventional thinking about beer, Jim brought the recipe to life with hopes drinkers would appreciate the complex, full-flavor and started sampling the beer in Boston.  He named the flagship brew Samuel Adams Boston Lager in recognition of one of our nation’s founding fathers, a revolutionary man of independent and pioneering spirit.  Today, Samuel Adams is one of the world’s most awarded breweries and remains focused on crafting the highest quality beers through innovation and experimentation in the relentless pursuit of better.  Samuel Adams remains dedicated to elevating and growing the American craft beer industry overall, including providing education and support for entrepreneurs and fellow brewers through its philanthropic program, Brewing the American Dream, which helps others pursue their American Dream.  For more information, visit
