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.
