Colheita ports are single vintage tawny ports, meaning that they have been aged in cask before being bottled. The 1994 Porto Pocas Colheita is superb with almost 20 years in cask before being bottled.ÊColheitas are considered by many (us included) the best deal in port. Notes of drying plum, fig, cinnamon and spice are balanced with almond, hazelnut and caramel. Delicious.
