A variety of beers can be paired with poutine depending on personal preference of the toppings, but the best match is a pale ale. The sharp bitterness is able to cut through all of the fatty ingredients and textures that go into poutine while the sweetness of the malt contrasts with the salty flavour.
An India pale ale could also be a good match as the higher levels of hops and carbonation work to cleanse the palette of the cheese and gravy.
Poutine combines a mixture of French fries, gravy, and cheese curds. Although it can be topped with almost anything, it is important to match your beer to the main ingredients.
