92 Points Robert Parker
The 20 year old Penfolds Grandfather Rare Tawny is a pale tawny color with a touch of brick. On the nose it is a bit spirituous and shows notes of raisins and fruit cake, some hazelnut and crème brulée. The palate shows even more nuttiness and depth along with greater freshness and acidity, though it seems drier than the Father. It finishes very long almost like a sweet oloroso or amontillado.

Readers can take their pick, but the difference in price might ensure that the Grandfather Tawny Liqueur is the way to go. Amazingly rich and honeyed with hints of figs, prunes, caramel, and toffee, it is a gorgeous, brilliantly made fortified wine composed of Shiraz and Mourvedre. This brilliant fortified is remarkably light on its feet given its massive richness. Thank good winemaking, great natural extract, and zesty acidity for keeping this wine fresh in spite of its huge residual sweetness and power.Source: Robert Parker (Wine Advocate) October, 2006 by Robert Parker
