Here, in 1883, James Concannon founded the Concannon Vineyard. The quality it achieved in Sacramental and commercial wines helped establish Livermore Valley as one of America’s select wine growing districts. Grape cuttings from this vineyard were introduced to Mexico between 1889 and 1904 for the improvement of its commercial viticulture.

Marker can be reached from Tesla Road.
