The 2008 Joseph Phelps Insignia is crafted from a meticulously selected blend of 89% Cabernet Sauvignon, 7% Petit Verdot and 4% Merlot. Sourced from renowned vineyards across Napa Valley, including Phelps` estate in St Helena, this wine underwent 24 months of maturation in 100% new French oak barrels. The 2008 growing season faced challenges, with spring frosts and a cooler summer contributing to lower yields, thereby enhancing the concentration of flavours in the grapes. Joseph Phelps Vineyards, established in 1973, remains a significant player in premium California wine.
