On Mendocino Ridge, a winemaker says wine’s real problem is trust

Mendocino County is wine country’s best-kept secret, and the proof is in the map. Tucked into one rural county is a baker’s dozen of distinct American Viticultural Areas — 13 federally drawn appellations, each its own argument about soil, fog, elevation and grape. They range from the smallest AVA in the entire country to a scattering of vineyards perched on ridgetops so high they sit above the clouds — islands in a sea of fog. Over the next 13 months, we’ll walk the county appellation by appellation: the ground, the climate, the grapes that found a home there and the growers betting on them.

MENDOCINO CO. 7/17/26 — Above the fog line, the air is clear, and the dirt is clean. Growing the wine was never the hard part.

The fog stays below, pooled in the valleys, while the vineyards sit on top of it like islands — which is how the ridge earned its nickname, Islands in the Sky. Only the ground above about 1,200 feet makes the appellation, so what’s left is a scatter of vineyard patches stranded on ridgetops over a sea of fog. Up here there’s no chemical drift, because there’s nothing on any side but forest. Mariah Vineyards has worked one of these islands since 1979, dry-farmed and never irrigated. What the family does now goes further — no synthetic chemicals in the vineyard, every wine lab-tested for traces of more than 500 of them. It’s about as clean and honest as a wine grape gets in California.
