Penfolds Grandfather Rare Tawny
Penfolds Grandfather Rare Tawny is batch-aged in old oak hogsheads for approximately eight years. After this stage it enters the six-stack ‘Grandfather Solera’, a fractional blending system utilised to maintain consistency in style. Each year winemakers draw one-twelfth of each barrel from the lowest level of the Solera. The barrel is then topped up from the barrel sitting above it and the process is complete when the barrels on the highest level are one-twelfth empty.
