Arnot-Roberts was founded in Healdsburg in 2001 by childhood friends Duncan Arnot Meyers and Nathan Lee Roberts. The focus of Arnot-Roberts is to produce distinctive, site-driven wines that highlight the nature of the unique terroirs in which the grapes are grown. Single-vineyard wines are the core of the production as well as a few appellation bottlings. 

The Peter Martin Ray Vineyard is on Mt. Eden in the Northeastern Santa Cruz Mountains, above the town of Saratoga. This site dates to the late 1800s, and was one of the first to be planted to Pinot Noir in California in the early 1940s.
