Highland Valley AVA
A New Chapter In San Diego Winemaking
San Diego’s winemaking heritage runs deep—long before the modern wine boom in Napa or Sonoma, vines were already being cultivated on Southern California soil. Highland Valley, nestled in the hills of North San Diego County, is part of that enduring story. The valley’s viticultural roots stretch back to 1893, when William Winn planted the first grapevines here. For decades, these sun-kissed hills nurtured vineyards that helped shape the region’s agricultural identity.
As time passed, the landscape evolved—vineyards gave way to avocado orchards, reflecting the changing needs and economics of farming. But nature, as it often does, brought transformation. After the Witch Creek Fire of 2007 and rising water costs, growers looked again to the resilient vine. The land responded. Today, Highland Valley’s decomposed granite and clay loam soils—paired with its warm days, cool nights, and coastal influences—form the foundation of an ideal microclimate for cultivating distinctive varietals like Muscat Blanc, Montepulciano, Tempranillo, Falanghina, and Sauvignon Blanc.
The Significance of AVA Status
The pending approval of the Highland Valley AVA (American Viticultural Area) is more than a regulatory milestone—it’s a moment of pride for San Diego’s wine community. AVA recognition officially affirms what local vintners have long known: this valley produces wines of character, shaped by place, soil, and spirit. The designation allows us to tell our story with greater clarity—to showcase our terroir and give wine lovers across the country a reason to discover the depth and diversity of San Diego wines.
It also signals a new era. With AVA status comes increased opportunity: expanded vineyard plantings, national visibility, and renewed investment in the craft. Highland Valley becomes not just a dot on the map, but a destination—an invitation to explore San Diego’s dynamic wine landscape.
