Since 1973, Pacheco Ranch Winery has represented one of the most unique endeavors in California's fabled wine country. Situated just below Napa and Sonoma Valleys, Pacheco Ranch's elegant winery and adjacent vineyards have produced a small quantity of uniquely hand crafted wines.

Ignacio Pacheco, one of California’s early pioneers, settled in what is now Marin County in 1840. He is believed to have been the first to plant grape vines in the region and his influence can still be seen in the names of places throughout the area.

Ignacio received a Land Grant for his services to the Mexican Government as the head of the customs house in Monterey, California. He was originally given the Agua Caliente Rancho grant in Sonoma, which he deemed “unsuitable for agriculture” and later exchanged it for the Rancho San Jose grant which consisted of 6,680 acres in what is now Marin County. Today, Pacheco Ranch is comprised of roughly 70 acres of the original Rancho San Jose Land Grant.
