Penfolds encapsulates a century and a half of winemaking and embodies the traditions of Australia fortifieds. Father 10 Years Grand Tawny Port is a multi vintage blend of Grenache, Mourvedre and Shiraz wines. Individual components are aged in small oak casks for at least ten years before being assembled into a most satisfying style of fortified wine. The active juices are treated to doses of brandy spirit, enriching the ferments and preserving natural fruit sugars, introducing complexity and contributing palate warmth. Individual barrels are topped up on occasion as the angels take their share, after which the choicest parcels are individually trialled to determine the final assemblage.
