During their long maturing period in oak casks, Old Tawnies undergo subtle colour changes. The deep red hue which characterises 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 lighter and gloriously smooth. It has a full, nutty bouquet, the classic Graham's richness and a soft lingering aftertaste.
