Codename : Westfort Pas St. Ambroise (2022)
Back mid/late 2000s, I discovered McAuslan St. Ambroise Oatmeal Stout while I was in Ottawa, it has been a mainstay of my beer consumption almost every trip into la Belle Province. Between the vital stats they list on their site, plus finding an enthusiast’s cloned recipe online, I have tried to emulate my own version.
