Chateau Canon is classified as a Premier Grand Cru Classé (Class B) in the 1996 St Emilion classification, this being one of the more relevant Bordeaux classifications (although admittedly that's not saying much) as it is at least updated from time to time. Nevertheless, Chateau Canon has not always met with universal approval from all critics, although in recent years, under the direction of John Kolasa, opinions do seem to be changing. Certainly my own experience of recent vintages, both grand and deuxième vin, suggest that there is much worth seeking out here.
