Heard a story once about 3.2 beer (US) and 5.0 beer (Canadian).
Company: Budweiser
Location: Baldwinsville, NY
Girl I went to college with, her father was 'up the chain' a bit at the Bud plant and said that the same vat, with the same beer filled bottles that would be shipped to US locations and Canada so I believe that the 'strength of beer' for Bud at least is a falacy, a marketing ploy, etc.
Now when you get into your real canadian beer, my experience would be with Bradors, you do think you are drinking crack. Your normal intake (to what feels to be intoxication) can be halved and you are wrecked. Cost a little more but you do get more bang for your buck and I know you used to get a good hockey trivia question on your beer cap.
