Origin: Multi-regional blend, South Australia.
Maturation: The initial maturation for Grandfather occurs as individual vintage and varietal components. These components remain in the same seasoned old oak hogsheads for approximately 14 years, before being selected and blended to form the topping wine. This topping wine is then introduced into the first stage of the Solera. The Solera is comprised of six individual stages with stage six supplying the wine for bottle at a minimum average blended age of twenty years.
Variety: All Penfolds tawny styles are created using a core selection of varieties made up of Mourvedre, Shiraz, Cabernet, and Grenache but are not limited to these varieties.
