This is probably the best homebrew shop in Montréal. An exceedingly vast selection and a really friendly staff. Best to e-mail your recipe to them a day in advance so that they have the chance to prepare your order. While they’re a wholesaler, they’re happy to deal with small-scale homebrewers and have great advice on substitutions during times of hop shortages(e.g. Amarillo, Citra, and Simcoe right now). Unbeatable.
