The Story of Chateau Margene

Chateau Margene is a producer of luxury Cabernet Sauvignon & Cabernet Franc from their estate vineyard in the Creston District of the greater Paso Robles AVA. They also produce Mooney Family Pinot Noir and Chardonnay from the Santa Lucia Highlands and port-style wines under the ROXO Cellars label. Their offerings are direct-to-consumer and only available at the estate winery, their 2nd tasting room on the Embarcadero in Morro Bay or through their wine club.

Now in their 22nd year, proprietors Michael & Margene Mooney began the fulfillment of their dream to plant a vineyard, build a winery and establish their home. 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. 

Michael handles the grape growing and winemaking with his younger son, Jon.  Margene oversees the Cabernet Franc program and runs the day to day operations with their General Manager Cate. 
Stella’s Vineyard was planted in 2014 to Cabernet Sauvignon & Cabernet Franc.  Due to prevalent disease issues throughout the West Coast, the original planting (Michael’s vineyard) had to be removed and re-planted in 2015/2016.  Michael’s vineyard consists of Cabernet Sauvignon, Cabernet Franc, Merlot, Malbec & Sangiovese (for their super-Tuscan-style blend). 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 to an 1842 Mexican Land Grant in San Luis Obispo County named Rancho Canada de Los Osos. 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
