During their long maturing period in oak casks, old Tawnies undergo subtle colour changes. The deep red hue which characterizes Port's purple infancy gradually gives way to a paler red. It then becomes amber - paler still - and eventually takes on a delicate brown, orange tinted colour. The pale amber Twenty Year Old is light and gloriously smooth. It has a full, nutty bouquet, the classic Graham's richness and a soft lingering aftertaste.
