Permutation is our experimental series of small batch offerings, showcasing the unique visions and innovative concepts developed by our production crew. The names are sequential, reflecting the brewing year in Trillium's lifespan, followed by a recipe indicator. It's no secret that we love the interplay between Barrington coffee and a blend of dark specialty malts. We've brewed many coffee stouts throughout the years, but we're continually experimenting with different roasts and bean varietals, exploring the range of how coffee can express itself in beer.
For Permutation 6.56, we brewed a viscous imperial stout and paired it with light roast Barrington coffee.Pouring a thick, dense black color, Permutation 6.56 is incredibly aromatic. Notes straddling the line between bakery and coffee shop are immediately present. Baker's chocolate, fresh-ground coffee beans, caramelized brown sugar, and fudge greet the palate. Medium-bodied and remarkably easy-drinking, Permutation 6.56 is rich with inviting roasty character.
Malt: American 2-Row Barley, Caramunich, C-60, C-120, Black Patent, Roasted Barley, Special B, Chocolate Malt
Hops: Columbus
Additional Ingredients: Barrington Coffee

Reviewing a can that I have had cellared for about a year.
Pours a pitch black with a small short lived head.
Smells and tastes of roasted malt, chocolate and very aromatic coffee. Has a bitter/ sweet finish with a slight alcohol warmth.
Medium heavy body with light carbonation. Lush syrupy mouthfeel.
Wish I had bought more cans!

Can from the brewery in Boston during the weekend of EBF 2020. Pours a very dark brown with a pillowy light tan head with nice lacing, smell is rich earthy coffee grounds, salty licorice, and hints of smoked peppers, taste is creamy rich fruity coffee with hints of earthy roasted peppers and dark chocolate, feel is medium bodied and well carbonated. And excellent creamy coffee stout!

Pours a dense black with a small tan head. Smells like a fairly typical imperial stout, with lots of dark dried fruits and roasty malt. Taste follows. Not getting much of the coffee, or at least no more than a plain imperial stout. Feel seems a little thin for the style. Good but not particularly distinctive. A little disappointing actually.

16 oz can pours black with two finger mocha head and substantial lacing.
Nose is gourmet ground coffee beans, bitter sweet chocolate, chocolate fudge cake and roasted dark malts.
Mouth is creamy and viscous, sweetness and bitterness in perfect union. Dark roast coffee, dark roast malts, bitter sweet chocolate burnt and brown sugar.
This is phenomenal. That is all!!

From the can, it pours a dark brown color with some clarity, however, it looks pitch black in the glass. A modest tan head dissipates quickly and yields a thin ring of lacing. Towards the final phase of the drink, the beer’s clarity reveals some nice ruby colors.
The nose is dominated by wonderfully fragrant notes of coffee, espresso beans and roasted malt. These are supported by rich aromas of dark toasted malts, cocoa powder and bakers chocolate, vanilla and a hint of dark fruit. Very pleasant to smell overall.
Full bodied with a moderately gentle carbonation. The mouthfeel is amazingly smooth and creamy. The flavors open with sweet notes of doughy biscuit, dark toasted bready malts, brown sugar, chocolate fudge and vanilla; very cola like at first. I feel that the drink really begins to come into its own as the coffee and espresso flavors open up and mesh with the roasted malts. These, along with earthy hops, add a nice bitterness that cuts through the initial sweetness. Furthermore, the high ABV is well hidden, neither boozy nor too hot. The finish is roasty, dry and has an espresso like bitterness.
Great imperial stout that is nicely balanced between malty sweetness and roasty bitterness. The coffee adjuncts, in particular, add a nice touch.

Black Pour, thin brown head on top. The smell of the beer has a heavy roasted aroma. The taste is really good, it's loaded with coffee and some sweetness to balance it all out. The feel is very smooth, silky and rich. Overall it's a really good brew, should've bought more than just a 4 pack.

Inky thick black pour. Smell of freshly perked coffee is noticeable, as is roasted malt. Flavors blend well; this is a mellowed stout that masks is potency very well. Glad to pick up a 4pk from the brewery and enjoyed this one.
