This bottle of Chinon Clos de la Dioterie 1990, Charles Joguet, had been properly stored since release. Many red Chinons made from Cabernet Franc are rather light, and sometimes seem closer to a pink wine than a red one. The cool climate typical of many years in parts of the Loire likely has much to do with this. However Cabernet Franc made in warm climates, including California, can be very dark and concentrated indeed. The year 1990 was very good in most of France including the Loire. This Chinon is very dark still and reminds one of the concentration of the Rhone. It is very concentrated, has much fruit of dark cherry and plum character, spice, and a taste of grape skins from old vines. There is enough acid to balance. The finish is quite long. If one had tasted only the usual commercial Chinons that get shipped to the US, you likely would not even think of this wine as coming from the Loire, but rather from many miles south. Apparently Chinons of this quality can take and benefit from several years of age. I have tasted a few commercial Chinons that were several years old, and time did not treat them kindly.
There has been considerable fuss recently about how global warming could make it too warm for the traditional red wines of Bordeaux. However, it could also be that such warming would make wines such as this Chinon possible on a regular basis as well as very full Pinot Noirs in Champagne.
