Tolosa Estate Grown Wines Tolosa’s style of winemaking reflects our commitment to quality. Our goal is to produce a perfectly balanced wine and to stay true to the characteristic of the grape varietal.  Selecting only the top 10% of the fruit from our Edna Ranch's 750 acres allows us to consistently produce distinctive wines. We produce estate grown wines that come from our vineyards planted in the cooler climate of Edna Valley, California.  Pinot Noir and Chardonnay make up 80% of Tolosa wines, while Syrah and other small production varietals make up only 20%.  Our winery is sustainable in all aspects of the wine growing and wine making process.
