Perched at 2,742 feet in California's Mendocino Ridge AVA, Signal Ridge Vineyard stands as the highest-elevation vineyard across Mendocino, Sonoma, and Napa counties. Since 1999, owner Roger Scommegna and winemaker Joanna Wells have crafted organically-grown, dry-farmed Pinot Noir and Chardonnay using minimal-intervention techniques that honor time-tested winemaking traditions.
