Located in Sonoma California, Gloria Ferrer Caves & Vineyards, specializes in producing sparkling wines, as well as Pinot Noir and Chardonnay. It was the first sparkling wine producer an Cameros and the first to plant Champagne grape clones in the region. Gloria Ferrer was founded in 1982 by the Ferrer family as their primary venture into California winemaking. Owners of Freixenet S.A., one of the primarily Cava producers in Spain, they fulfilled the family's lifelong dream of producing wine in the United States. The winery’s tasting room originally built in the 1980’s is attached to the winery and is open to the public for tasting and seasonal vineyard tours, they also offer special events and a membership program. The winery is known for its culinary programs featuring estate-grown produce and its variety of events. The architecture is a tribute to Spanish and California mission design, designed to celebrate the Catalan tradition of the Ferrer family. The red tile rooftop and stucco walls are a throwback to the Ferrer family 11th century farmhouse in Sant Sadurní d'Anoia.

An extensive cave and tunnel complex sits directly below the tasting room and through the years the caves became underutilized and primary used for equipment storage. Brereton was approached by Gloria Ferrer to explore the idea of renovating the caves and tunnel system to expand the winery’s capacity to host events and weddings. The overall program included a reception lounge, restrooms, catering kitchen, private tasting room, pre-function space and main event hall located in the winery’s largest cave. The concept for the event space was to respect the buildings existing historical references while infusing a decidedly more modern Italian design approach. The color palate and materials were carefully selected to incorporate the established brand but be largely neutral so that the space could be transformed to accommodate a specific event.
