The 13th hour is the witching hour, and a time when strange brews can occur. With 13 ingredients, we combined the roasted chocolate and coffee flavors of a stout with the complex spicy character of a Belgian-style ale aged in oak for a deep, robust, and captivating brew.
Every Craft Beer
Has a Story
The thirteenth hour is the witching hour and refers to the mysterious combination of flavors in this brew. Samuel Adams® Thirteenth Hour is a complex blend of thirteen ingredients. We use seven different specialty malts to give the beer its smooth, rich and roasted maltiness. We've combined the roasted chocolate and coffee flavors of a stout with the spicy character of a Belgian ale aged in oak.
The traditional roasty malts in Thirteenth Hour are taken in a new direction by the unexpected character of Kosmic Mother Funk (KMF) that add a layer of complexity and flavor with hints of oak, peppery spice, dark fruit, and a hint of acidity. KMF is an ale that we’ve aged in large oak tuns for over a year where it undergoes a secondary fermentation to give the beer a rich tropical fruit note and some sourness. The beer is also bottle conditioned which creates another fermentation giving the beer an extra smooth and balanced flavor.
We first began experimenting with barrel aging over 15 years ago in our Boston Brewery, taking cues from the ancient brewmasters of Belgium. Belgian beers are known for the distinctive character of their yeasts and the practice of aging and blending beers. These specialty yeasts present a wide array of flavors and are matured through a process of blending and aging portions of the beers in wooden tuns. For Thirteenth Hour we combined our signature KMF with a roasty stout for an American creation that’s full of deep complex flavors.
