Foley Family Wines, the rapidly expanding Healdsburg company, has announced a partnership with Langtry Estate & Vineyards to oversee sales and marketing for Lake County's largest winery.

Financial terms were not disclosed in the announcement.

Langtry, best known for its Guenoc brand, produces about 175,000 cases per year and spans 23,000 acres in Lake and Napa counties. It became the first winery with its own appellation when the Guenoc Valley AVA was established in 1981.

"Langtry and Guenoc are the two most recognizable and important brands from Lake County," owner Bill Foley said in a statement. "The addition of their wines will strengthen our portfolio and help us gain access to a number of important national and regional accounts."

Foley entered the wine business in 1996 and owns more than a dozen wine brands, including Chalk Hill and Sebastiani in Sonoma County. His growing company produced 950,000 cases last year. In the last two months Foley also has announced acquisitions in Napa and New Zealand.

Langtry originally was purchased by British theater start Lillie Langtry in 1888. She led the winery until selling the property in 1906, according to the winery's website. The winery and vineyards were inactive during and after Prohibition and were acquired in 1963 by Malulani Investments, which planted Bordeaux grape varieties and focused on producing wines from Guenoc Valley.
