Elyse is a Napa Valley winery founded in 1987 by Ray and Nancy Coursen. Ray grew up on a New Jersey dairy farm and attended agricultural college before moving to the Napa Valley to pursue winemaking. Nancy is a third-generation Californian who met Ray and joined him in establishing their own winery. Ray worked for several Napa producers before starting his own label, which is named after the couple’s daughter. The Coursens source grapes from Napa Valley growers. In 1998 they started a second label, Jacob Franklin, named for their son. Robert M. Parker Jr. notes that "these wines are at least very good, and often outstanding, as Coursen knows how to coax high quality out of Zinfandel, Petite Sirah, and Cabernet Sauvignon..."
Carneros AVA, also known as Los Carneros, is at the southern end of the Napa and Sonoma Valleys at the top of the San Francisco Bay. The 8,000 vineyard acres are mostly planted to Pinot Noir and Chardonnay, both of which thrive in the district’s cool, marine climate. Carneros became an AVA in 1983 and it has attracted foreign wine companies along with local producers. It has been especially appealing to European producers of sparkling wines including the giant Spanish cava producers Codorniu and Frexinet, and the French Champagne house Taittinger. Codorniu in Carneros is called Artesa, and Frexinet’s Carneros brand is Gloria Ferrer. Taittinger calls its Carneros winery Domaine Carneros. The European producers also make still wines in Carneros.
