It seems I stopped drinking a lot since I finished my engineering degree.. before that it was Molson*.* since it was always the available brand at any party..
And since Canadian beer as higher standards than US beers, it's not bad.
But honestly, I prefer beers done by small breweries.. the only one I really like is Heineken (which is actually brewed by Molson in Canada), other than that mainstream one.. I can drink mostly anything.. but we have some very nice breweries over here, if you ever have the chance to taste any of the Unibroue beers, go ahead ;)
"La Maudite", "La fin du monde", etc...

Not too high on anything else than beer & whine though.. I like Bailey's a LOT, like B-52's drinks too ;)
