The beautiful Quinta do Noval is undoubtedly the most famous port producer, largely because their 1931 and 1927 were to vintage port what the 1947 Cheval Blanc and 1945 Mouton-Rothschild were to the Bordeaux trade - divine, monumental wines of extraordinary depth of flavor. Also, the Quinta do Noval produces a rare vintage port from a small vineyard of ungrafted, pre-phylloxera vines called Nacional. It is so rare that I have never seen, much less tasted, a bottle of what is supposedly a great port. However, the truth of the matter is that recent vintages of Quinta do Noval have not been nearly as impressive as they should be. Commentators have described the wines as light, elegant, and charming when in fact they lack richness and depth of flavor.
