Moon Mountain District
Location: California, United States
Legal name: Moon Mountain District Sonoma County
Region: Sonoma County
Nested under: Sonoma County
Moon Mountain District is an eastern Sonoma mountain AVA on the Mayacamas side of the county. Cabernet Sauvignon is especially important, joined by Zinfandel, Merlot, Syrah, and other structured reds that often show dark fruit, spice, volcanic-soil savor, and firm tannins. For drinkers, the AVA signals Sonoma mountain Cabernet character rather than the cooler Pinot-and-Chardonnay image of western Sonoma.

Recent Vintages
Recent Sonoma County vintages have generally tracked the broader North Coast pattern: drought and heat pressure in several years, uneven smoke concerns in 2020, and a more forgiving 2023 after a wet winter and moderate growing season. Cooler, coastal-influenced districts often had more natural freshness in warm years, while warmer inland areas could show riper, more concentrated profiles. Because smoke exposure and harvest timing varied by site, 2020 should be treated as producer- and vineyard-specific rather than as a simple region-wide verdict.
A general read of growing-season and harvest character — not a rating.
