Open Wine Lookup →History
The name derives from Saint John, a common place name in early California. Commercial grape farming in the area traces back to 1963, when Robert Young established a vineyard here. The AVA was officially recognized on October 8, 2014, as part of a broader reorganization that created 11 sub-appellations within Paso Robles. Today, no winery brands are headquartered within San Juan Creek; the vineyards function as premium source vineyards supplying producers throughout the Paso Robles region.
