Owned by the Martinelli family since the 1860s and maintained by family members Carolyn Charles and her two sisters, Charlotte and Donna, Three Sisters was planted to Chardonnay back in 1980. Formerly part of the largest sheep ranch in Sonoma County. The fruit benefits from the maritime influence of the nearby Pacific Ocean which provides cool daytime breezes during bright sunny days to ensure optimal ripening and chilly evening fogs that encourage lively acidity and verve.
