Ah, finally getting into the Canadians, eh? Good to hear. If you like Centennial, try these from the same distillery:
Century Reserve Lot 1525 ($30 from the LCBO). Aged 15-25 years.
Century Reserve 21 year old ($48.95). Pure corn whisky, apparently. Very, very nice, but subtle. Probably the smoothest whisky I've ever had, if that counts for something.
What I'd really like to get, but can't find without a trip to Canada, is Alberta Premium. I have friends in upstate New York who travel to Canada periodically but they've repeatedly forgotten to pick me up a few bottles when they head over the border. Nothing like an unreliable "mule" when you've gotta get your rye fix.
