About Corteza Vineyards
Corteza Vineyards works the Knightsen corner of eastern Contra Costa, part of the current county grower and winery community in one of the region's quietest agricultural pockets.
The winery is most closely associated with small-production estate work, and no dependable recurring public schedule is confirmed; the vineyard location is private.
Follow the label through the county's grower channels and events; Knightsen's farm quiet is the point, not an obstacle.
