I tasted this at Whisky Live in Toronto recently. It was my first sample, so my palate was good. It has a nice chestnut color, not as dark as I thought it might be. The nose seemed fairly mild. The taste was round with good wood notes and residual sweetness. Nothing really jumped at me though, it seemed of a piece with younger CCs I've had including the 20 and 15 year old versions. It seemed older than those to be sure, but not significantly. I did not get any "big" flavors such as I notice in Wiser Small Batch or Forty Creek Double Barrel Reserve, for example. I asked the reps about the background to the age expression. They said some years ago it was decided to age CC longer than normal (20 was the previous maximum age I believe) to honor an anniversary of Hiram Walker, now 150 years old.
Pernod Ricard owns the historic Walkerville, Ontario distillery that Hiram Walker founded in the 1800's. Beam Global Brands owns the CC brand. More than that I do not know and I've assumed the former makes the whisky for the latter under contract (but am interested in more information if available).
CC is good whisky, always has been. The 30 years version won't displease anyone who likes CC - au contraire - but I think it is fair to say it does not break any molds, either. In style it reminds me a fair bit of Crown Royal Special Reserve. Its price tag is high for Canadian whisky but the run was small I was told and the package is very nicely done.
