📜 History

Deep roots and revival through adventure:

  • First vines planted in 1881 by Joseph Vorbe, with early viticulture ebbing during Prohibition.

  • Fast-forward to 1978, when John Newmeyer replanted vineyards around Heron Lake, igniting a modern rebirth.

  • 1988 marked its recognition as an official AVA, the third sub-appellation of Napa.

🧠 What to Know

Here’s what makes Wild Horse Valley distinct:

  1. Coolest Napa AVA – Elevated above the fogline and cooled by Bay breezes, it's even cooler than Los Carneros.

  2. Volcanic, stress-inducing soils – Thin, well-draining, red basaltic soil produces intensely concentrated fruit.

  3. Stark microclimates – The western side is cool and maritime-influenced; the protected eastern side warms considerably.

  4. Tiny and underplanted – Only about 100 acres are planted out of 3,300 total—making its grapes incredibly prized.

  5. Pinot & Chardonnay stronghold – Cooler grapes shine here; some Cabernet exists, but remains rare and lighter in style.

📍 Where It’s Found

  • 🇺🇸 Wild Horse Valley AVA – Nestled high in the Vaca Mountains, southeast of Napa town, spanning parts of Napa and Solano counties.

  • ⬆️ Elevation: ~850–2,130 ft / 260–650 m—most vineyards rise above the fog and bask in cooler air.

  • 🌞 Climate: The coolest microclimate in Napa, with western breezes up from the Bay cooling vines as much as 10°F more than Carneros.

  • 🌡️ Temperature Summary: Summers remain subdued, rarely topping 90 °F, with consistent cool influence, giving long hang time.

  • 🔺 Warming Trend: No AVA-specific data, but Napa-wide rising temperatures could gradually impact ripening nuances.
