As a cheddar matures, its fats and proteins undergo biochemical changes that produce flavor compounds. So the older the cheese gets, the sharper, or more intense, it is likely to be. Old Quebec Vintage Cheddar is an extra-sharp cow’s milk cheddar (aged at least three years), with a smooth texture, a full-bodied flavor, and a tangy finish. Serve with ripe pear, a piece of apple pie, on a burger, or grill it between two slices of crusty bread. Also terrific on its own with a nice Cabernet or Syrah, a fruity red wine.
