The 2016 Purlieu Missouri Hopper Vineyard Cabernet Sauvignon in Magnum (1.5L) is a wine of historic significance, profound maturity, and the kind of fully realized, magnificently developed single-vineyard Napa Valley Cabernet Sauvignon that can only emerge from the combination of an exceptional vineyard site, a celebrated vintage, and the ideal aging vessel. Now a full decade from harvest, this magnum of Missouri Hopper has reached a stage of magnificent complexity and completeness: the 2016 California vintage — one of the most consistently praised and age-worthy of the modern era, producing red wines of extraordinary concentration, structural integrity, and the natural balance for exceptional longevity — has developed with breathtaking grace in the magnum format, where the wine's evolution has been slower, more harmonious, and ultimately more profound than any standard bottle could achieve. The Missouri Hopper Vineyard's Oakville terroir speaks with full authority in this mature expression: aromas of dried black cherry, cassis, cedarwood, dark tobacco, leather, iron mineral, dried herbs, and a magnificent earthy complexity of profound depth and richness lead to a full-bodied, silky, completely integrated palate with resolved tannins and a finish of almost boundless length and satisfaction.
