Graham's was founded in 1820 in Portugal's Douro Valley and sits among the country's elite Port houses. For their aged Tawny Port bottlings, Graham's sources grapes from the pure schist soils of vineyards in the hot, dry mesoclimate at the heart of the Douro Valley. The 20-year is a distinct step up from Graham's 10-year, with a signature nuttiness and powerful thrust of flavors highlighted by orange peel and spice. Fine acidity drives the finish, which should really be graded on a different scale than what other wines would consider 'long.' One begins to think it may never end.
