Much of the beauty of Retzlaff Vineyards lies in its commitment to organic practices. As a pioneer in organic grape growing, Retzlaff stands out as the only California Certified Organic vineyard in the greater San Francisco Bay region, making it a must-visit for wine lovers.

The vineyard’s dedication to organic methods, along with meticulous canopy management and vineyard health, results in wines of exceptional quality. Visitors can savor the authenticity and complexity of wines crafted from grapes that are free from chemical residues.

The clean, bright, and evenly ripened fruit translates into fresh, delightful wines that showcase the true nature of each grape varietal. The winemaker often likens their approach to savoring an organic, sun-kissed peach plucked directly from the tree, striving to ensure that each berry in the vineyard embodies that perfect peach experience. For California wine enthusiasts, a visit to Retzlaff Vineyards promises not only exquisite wines but also a deep appreciation for the beauty of organic viticulture.

Fenestra Winery was established by the Replogle family on the historic Ruby Hill property in Pleasanton in 1976. In 1980, the winery moved into the century-old George True Winery building on Vallecitos Road in Livermore. The building, which had suffered from years of neglect, required significant restoration; the Replogles removed tons of trash, installed a new roof, and reinforced the structure. In 1997, the winery building underwent further refurbishment, and vineyards were planted around the property. Specializing in classically balanced, award-winning wines primarily from Livermore Valley grapes, Fenestra Winery is recognized as Livermore Valley’s first boutique winery and has celebrated many years of producing fine wines.

Brett Caires, a self-made realtor, chef, and winemaker, hails from the stock of wine connoisseurs. BoaVentura Baptiste de Caires, Brett’s grandfather and the winery’s namesake, handed down a passion for relishing good wine. Brett recalls family meals with his Oakland, California-based grandparents, where wine was always a staple at the dinner table: “The table was set with glasses of wine, port, and milk.” To boot, according to family legend, Brett’s great grandfather, Antonio de Caires, was deported during Prohibition for winemaking after he brought his family to America. A devotion to his family heritage was a natural inspiration for Brett to cultivate his own knowledge of winemaking.

Through the influence of family, friends, and fellow winemakers, including Karl Wente, Noah Taylor, and Bob Taylor, Brett learned about the art of making wine. On a trip with Karl to Europe in 1997 – through France, Greece, Portugal, and England – he sampled regional wines, amassing knowledge that would later help him produce his first Cabernet, made available to the public in 2002.

On April 29, 1999, Brett realized his dream of owning a winery when he and his wife, Monique, purchased a five-acre property perched atop a sunny ridge in the southeast corner of Livermore Valley, California.
