Chateau Canon

I used to buy Ch. Canon fairly often about 20 years ago, but I have bought none since then. Thus I do not know most of the wines you mention. I still have a lone bottle of the 1976. My guess is that it is too old. Many of the 1976s were a bit low in acid and not for the long haul. But who knows. When I open it I will post notes, unless I have to pour it down the sink.
