Back in the 80's the Canadians wanted U.S. Whiskey and Americans wanted Canadian beer, That was when Brador and Export were something like 5-6% alcohol and U.S. beer was 4. I forget the reasoning around the Whiskey.
I recall hand importing Brador into the US back in the mid 1980s.
I just purchased a 12 pack of Canadian migrants earlier today and I’ll soon take them to the local lake and feed some fish.
