Very few Ports can age for 40 long years and still show the complexity and flavours that can be found in Dow’s 40 years. At any one time only 6 or 7 casks in the ancient cellars of Dow’s in Vila Nova de Gaia are available to be bottled for this very rare and fine Port, the remaining barrels of Port in cask are on the long and slow journey to reach this pinnacle of the Port tasters art.
