1994 Mondavi Carneros Chardonnay - not as dark in colour, and the oak in the nose, which used to dominate, has finally melded into a harmonious whole, with toast and lemon. In mid-palate, cleaner and not quite as heavy, and the finish was oddly enough quite similar to the Australian wine, with a definite mineral note you don't see very often in American Chardonnay. Tasted blind, I'd have said this was the younger wine.
Both wine were quite pleasant, although many people would deem them over the hill. It takes a special sort of person to enjoy 'mature' chards!
