Entreprise brassicole établie en 1989 dans le cartier St Henri a Montréal. Fabricant de gamme St Ambroise,. La Brasserie a recueilli jusqu'ici plus de 12 médailles à des concours internationaux, dont une médaille de platine, quatre d'or, six d'argent et une de bronze. McAuslan Brewing began operations in January of 1989. Located at 4800 St-Ambroise Street in Montreal’s St-Henri district, it has established itself as Quebec’s foremost micro-brewery. The brewery launched its first beer in February 1989. St-Ambroise Pale Ale was an immediate success. Its distinctive hoppy-ness and clear reddish hue set it apart and gained it an instant following. Shortly after, McAuslan Brewing became the first micro-brewery to offer its product in bottles. Since that time, McAuslan Brewing has steadily expanded both its brewing capacity and its place in the market. In the ten years since launching St-Ambroise, the brewery has introduced four new beers: St-Ambroise Oatmeal Stout in December of 1991; the Griffon brands, Griffon Extra Pale Ale and Griffon Brown Ale in April of 92.
