What is the Napa Valley AVA?
(pronounced “NAH-pah”)

The Napa Valley AVA is California’s first American Viticultural Area, established in 1981, and one of the world’s most prestigious wine regions. This compact valley stretches just 30 miles long and a few miles wide, yet produces some of the planet’s most celebrated wines despite accounting for only 4% of California’s total grape harvest.

Understanding the Napa Valley AVA System

An AVA, or American Viticultural Area, is a designated wine grape-growing region that recognizes unique geographic and climatic features. For a wine to carry the Napa Valley AVA label, at least 85% of its grapes must come from within the valley’s boundaries.

The 17 Sub-AVAs Within Napa Valley

What makes Napa Valley truly special is its nested structure of 17 distinct sub-appellations, each offering unique terroir:

Valley Floor AVAs:

  • Oak Knoll District, Yountville, Stags Leap District
  • Oakville, Rutherford, St. Helena, Calistoga

Mountain AVAs:

  • Howell Mountain, Mount Veeder, Spring Mountain District
  • Diamond Mountain District, Atlas Peak

Coolest Climate AVAs:

  • Los Carneros (shared with Sonoma)
  • Wild Horse Valley

What Makes Napa Valley AVA Special?

The valley’s Mediterranean climate creates perfect conditions for premium grape growing, with warm, dry summers and mild, wet winters. Home to over 400 wineries and 700 grape growers, Napa Valley is famous for producing exceptional Cabernet Sauvignon, though each sub-region specializes in different varieties based on elevation, soil, and microclimate.

Why not explore different Napa sub-regions? You might be surprised by how dramatically the wines change from the cool, foggy Carneros to the mountain-top vineyards of Howell Mountain, each telling its own unique story of place and passion.
