Notes - Cockburn's is the largest landowner in the celebrated "Douro Superior" region of the sweeping Douro River Valley of Portugal, where all authentic port is produced. This assures large resources of the finest wines for its blends. Simply put, Cockburn's has historically been more conservative than other port houses in declaring a vintage, choosing to declare only those years that best suit its elegant, less sweet style. Before declaring, Cockburn's blenders taste, categorize and identify those wines that might ultimately become a vintage blend. Only after this rigorous two-year selection process is a final decision made. 1997 was truly an excellent year in the Douro Valley. The harvest was one of the longest in living memory. At the far eastern extremities of Upper Douro, picking began before the end of August and continued until the second week of October in the cooler areas of the Cima and Baixo Corgo. The crop was small and produced grapes with wonderfully concentrated flavors, providing outstanding wines with excellent structure and an intensely fruity aroma. Aged two years in (old) wood and bottled unfiltered, vintage port usually demands at least 10-15 years of bottle age to soften its powerful tannins and permit the robust fruit elements to marry and harmonize. Vintage port is usually considered fully mature after 30 years.
