The 1967 Colheita Tawny Port Dalva is a field blend coming in at 145 grams per liter of residual sugar. It is surprisingly young for its age, the wave of sugar hiding the complexity. Very sweet on the finish, this does have those old tawny nuances underneath. There's bark and molasses to go with the sugar and caramel. It seems rich, but not overly concentrated. The most impressive part is the finish. It lingers beautifully. In fact, it is hard to get it out of your mouth. You may be tasting it the next morning. While, on first taste, the 1985 actually seems more complex and this 1967 seems a bit too sugary, this eventually proves that it has the goods. The long finish alone demonstrates that nicely.
