For this sixth edition of our Collaboration Series, we invited Matt Brynildson, brew-master of our sister brewery Firestone Walker, to join Boulevard brewmaster Steven Pauwels in our barrel-aging cave. Armed only with their palates, some graduated cylinders, and a bunch of tulip glasses, they arrived at the perfect balance of two barrel aged beers from each brewery. The blend celebrates the individual characteristics of each of the four while creating something entirely new and unique.

COMMERCIAL DESCRIPTION
The Collaboration series is our way to bring shared beer ideas to life with some of our favorite brewery friends from around the world. This year, we bring you a specially blended, barrel-aged beer with the help of our sister brewery in California, Firestone Walker. With Collaboration No. 6, Brewmasters Steven Pauwels and Matt Brynildson have created a big, bold flavor combination by blending two Boulevard beers and two Firestone Walker Beers in the following percentages:

Boulevard Bourbon Barrel Quad – 45%
Based loosely on the Smokestack Series’ The Sixth Glass, this abbey-style quadrupel is separated into a number of oak bourbon barrels where it ages for varying lengths of time, some for up to three years. Cherries are added to make up for the “angel’s share” of beer lost during barrel aging. Selected barrels are then blended for optimum flavor. The resulting beer retains only very subtle cherry characteristics, with toffee and vanilla notes coming to the fore.
ABV – 11.8, IBU – 19

Firestone Walker Stickee Monkee – 35%
Brewed with Belgian candi sugar and aged in a selection of fine bourbon barrels, Stickee Monkee trailblazes its own category as a “Central Coast Quad.” The name Stickee Monkee is a nod to the Central Coast’s native Sticky Monkey flower, as well as a shout¬‐out to the Belgian monks who pioneered the Quad style. The Belgian candi sugar imparts a signature molasses sweetness to the beer. Meanwhile, maturation in bourbon casks brings ample barrel expression with notes of toasted oak, coconut, leather and cigar tobacco.
ABV – 13, IBU – 45

Imperial Stout X – Tart Cherry (Whiskey Barrel-aged) – 10%
Our special treat for lovers of big, complex stouts, the Imperial Stout “X” series offers a year-long roster of limited releases, each with a significant variation. This riff spotlights the addition of tart cherries to fermentation as well as a lactic souring on the brewhouse. The result is a perfect marriage of robust, smoky maltiness and bracing tartness. Unlike the release version of Imperial Stout X – Tart Cherry, this portion was briefly aged in previously used whiskey barrels.
ABV – 11, IBU – 64

Firestone Walker Velvet Merkin – 10% Velvet Merkin is the beer that almost wasn’t…Indeed, this vintage oatmeal stout’s comical (or is it scandalous?) name went off the grid for several years, but now it’s back due to popular demand. Velvet Merkin is aged for a full year in retired spirits barrels from Heaven Hill, Woodford Reserve and others, yet manages to offer mind-¬boggling balance and restraint. You will wig out when you taste Velvet Merkin’s rich milk chocolate, bourbon and espresso flavors, preceded by aromas of vanilla, coconut, toasted oak and mocha. ABV – 8.5, IBU – 33

==Introduction==

Just when I thought I’d never see something like this, I was really amazed. At first I saw it as a Boulevard and Firestone Walker collab but when I realized that it was a Cuvee of some of both breweries best beers, I realized that this was a must get. I have reviewed each of these beers in the past, except for the Tart Cherry Stout X but the other ones were definitely at that World Class tier beers. So being that Firestone Walker was involved, I knew this would of came up to possibly be one of the best and unique Cuvees. Now, we can only hope that this is the case, let’s have a sip, cheers!

Dark Crimson Amber full body, smooth, creamy, velvety, chewy and syrupy mouthfeel and sipping drinkability.

Overall:
The Quad aspect takes over more than the stout blend but even that being the case, it does not change this from being a definite bucket lister in my mind. Having Firestone Walker who are experts at barrel aging and cuvee blending, this is no surprise that this came out the way it did. The complexity of the 2 Belgian Quads and the 2 Stouts collide into a super decadent dessert that really has taken things to another level. I highly recommend this one for those that are fans of these breweries, beers and styles! This is one for the masses!
