Handley produces Pinot Noir and Syrah from vineyard sites across Mendocino County's Anderson Valley and Redwood Valley. The Estate Vineyard Anderson Valley Pinot Noir and RSM Vineyard Anderson Valley Pinot Noir represent the winery's focus on the cooler Anderson Valley appellation, where Pinot Noir thrives in maritime-influenced conditions. The Kazmet Vineyard Redwood Valley Syrah draws from warmer inland terrain. These wines have been assessed by Wine Enthusiast, Decanter, Wine Advocate, and Wine Spectator. The North Coast location positions Handley within California's most established cool-climate region, where diurnal temperature swings and fog-moderated growing seasons shape wines of structure and aromatic precision.
