With each vintage, varietal batches are selected for Grandfather. These batches are individually aged in seasoned old oak casks before being blended together at 14 years of age. This blend is then introduced into the 'Grandfather Solera'. This Solera consists of six stages that are designed to fully integrate all components offering consistency and freshness with a final minimum average blended age of 20 years. Deep amber/mahogany in colour with green-gold tinges, this is a blend of the finest old tawnies. The palate shows classical Penfolds fruitcake, liquorice and vanillin oak flavours with a sweet full and round mid-palate, and a finish that persists on and on.
