The Story of Chateau Margene

Chateau Margene is a producer of luxury Cabernet Sauvignon & Cabernet Franc sourced excusively from their estate vineyard in the Creston District AVA. They also produce Pinot Noir and Chardonnay sourced from the Santa Lucia Highlands under their Mooney Family label and port-style wines under the ROXO Cellars label. Their offerings are 100% direct-to-consumer and only available at their two tasting rooms or as a member of their allocation program.  

Now in their 23rd year, proprietors Michael & Margene Mooney began the fulfillment of their dream to plant a vineyard, build a winery and establish their home in 1997.  The family took up residence on the property in the Summer of 1998 and planted the estate vineyard in the Fall of 1998, where they still live today. Total production is 2,500 – 3,000 cases annually. 

The two vineyard blocks on the estate are Stella’s Vineyard, planted in 2014 to Cabernet Sauvignon (Clones 47 & 4) & Cabernet Franc.  Michael's Vineyard, initially planted in 1998, was re-planted in 2016 due to disease issues.  It consists of Cabernet Sauvignon (Clones 47, 33 & 6), Cabernet Franc, Merlot, Malbec & Sangiovese (for their super-Tuscan-style blend, Cielo Rosso). Farming practices are organic & sustainable with the family doing the majority of the vineyard work and property management.  

Michael’s family history in California dates back seven generations with his great, great grandfather being deeded a Mexican Land Grant in 1842 -Rancho Canada de Los Osos in San Luis Obispo County.  The grant extended from the Pacific coast along Los Osos Valley toward present day San Luis Obispo and encompassed part of Montana de Oro State Park
