About Napa

Napa Valley AVA is the most editorially significant American wine region — a 30-mile valley northeast of San Francisco bounded by the Mayacamas Mountains (west) and the Vaca Range (east). The valley has 16 nested sub-AVAs (Oakville, Rutherford, Stags Leap District, Mount Veeder, Howell Mountain, Spring Mountain District, Diamond Mountain, Atlas Peak, Pritchard Hill, others) each with distinct climate, soil, and stylistic identity. Cabernet Sauvignon is the dominant grape (about 40% of plantings) and the wine the region is editorially known for. The 1976 Judgment of Paris tasting — in which Napa Valley Cabernets (Stag’s Leap Wine Cellars 1973) and Chardonnays (Chateau Montelena 1973) beat top French wines in blind tasting — established Napa’s international credibility. Modern Napa Cabernet prices reflect collector demand: foundational producers (Opus One, Screaming Eagle, Harlan, Sloan, Bond) routinely retail at $500-5000+ per bottle. The region’s editorial range spans foundational (Heitz, Mayacamas, Phelps Insignia) to cult (Screaming Eagle, Harlan) to commercial (Robert Mondavi, Beaulieu).

Editorial notes

Practical guidance

Modern Napa Cabernet ages 15-25 years from strong vintages. The 16 sub-AVAs matter editorially — Oakville Cabernet (Opus One, Screaming Eagle, To Kalon) differs significantly from Howell Mountain (more powerful, more tannic). The 2005, 2007, 2012, 2013, 2016 vintages are recent landmarks.
