The 2018 Patel Coombsville Cabernet Sauvignon is a wine of beautifully developed complexity, exceptional cool-climate Coombsville character, and the kind of gracefully evolving Napa Valley Cabernet Sauvignon personality that reveals the extraordinary aging potential inherent in Patel's meticulous farming of one of Napa Valley's most distinctive and exciting subappellations. Coombsville — Napa Valley's most southeastern corner, where the persistent cooling influence of San Pablo Bay moderates temperatures throughout the growing season and encourages a naturally fresh, mineral-driven, and elegantly structured style of Cabernet Sauvignon unlike anything produced in the valley's warmer, more celebrated corridors — produces wines of outstanding longevity and the kind of thoughtful complexity that rewards cellaring with real distinction. Now with several years of graceful bottle evolution, the 2018 Patel Coombsville has entered an excellent secondary drinking window: the vintage's natural concentration and fine tannin structure have integrated beautifully, revealing aromas of dried dark cherry, cassis, cedar, graphite, leather, dried herbs, iron mineral, and a developing earthy complexity of genuine depth and refinement that speak directly of Coombsville's unique terroir voice.
