Big Rock Birch Bark Canadian Imperial Stout

Calgary’s biggest brewery Big Rock has been attempting to reclaim its roots as the vanguard of Alberta craft beer over the past few years. For a long time Big Rock has settled into a position of making the same 6 or 7 beers and never breaking stride. Then this movement of craft beer hit Calgary about 4 years ago and Big Rock started to take the time and energy to create more unique and craft centric brews. As someone who has been a craft beer nerd in Calgary since turning 18 in 2006 when the choice of good beers were slim pickings Big Rock was many of my first beers as non-minor. Birch Bark is a part of Big Rock’s Alchemist Series of beers that have been crafted with the intention of trying to regain former glory. Birch Bark is a Russian Imperial Stout brewed with Birch syrup, Fuggles and Challenger hops to a weighty 8.5% ABV.

Birch Bark pours out a thick syrupy sludge of purely opaque black with a nice fizzy body that settles into a dense tan head perched atop creamy with a marshmallow esque top. The aroma is quite impressive and has a nice rich and robust malt with heavy roasted notes and notes of light vanilla and earth. A thick body on the first sip with noted sweetness akin to syrup with a slick full bodied mouthfeel. The roasted malts are heavy and present with nice woody and roasted notes. Overly sweet in the middle with a light roasted bitterness on the finish. Lighter notes of coffee, dark chocolate and a pinch of spice also present themselves. The finish although firmly rooted in roasty bitterness has a light fruity component that accompanys a balancing floral and citrus hop. This is hands down the best beer Big Rock has ever made despite being oriented for the most discerning of palates. I appreciated the attempt of an Imperial Stout which is bold in its own right but to use Birch syrup to enhance the flavour with a woody flavour was impressive. The only downfall being the overly intense sweetness throughout the profile. 

Grade: 85/100
