Vineyard History

After the untimely death of Giuseppe Martinelli, his twelve-year-old son, Leno, was given sole responsibility of farming the 60-degree slope vineyard that Giuseppe planted upon coming to Sonoma County. Leno grew up receiving all of his farming and winemaking knowledge from his parents and from his own lifelong experience. This rugged section of the ranch is referred to by the Martinelli family as "Jackass Hill", because only a jackass would farm a hill that steep. Jackass Hill is the steepest non-terraced hillside vineyard in Sonoma County. At age 89 Leno turned over the caretaking of the steep hillside vineyard to his son, Lee Sr. Lee is the third generation of Martinellis to caretake the original family homestead land; farming the ancient vineyard much as his grandfather Giuseppe had one hundred years before, without irrigation, pesticides, or trellising.
