The Great American Wine Company, by Rosenblum Cellars, is a tribute to the pioneering spirit of America. We proudly use the finest grapes from California vineyards to pay tribute to classic American varietals and winemaking techniques. In tribute to our American heroes, we donate to U.S. military charities to support our troops and veterans each year.

Rosenblum Cellars is owned by the fifth largest winery in the U.S., Bronco Wine Company. Founded in 1973 by Fred T., Joseph S. and John Franzia, Bronco Wine Company is a family-owned winery committed to growing, producing and selling the finest quality wines of the highest value to our customers. Bronco Wine Company’s diverse family of brands is sold in over 90 countries worldwide in addition to being distributed throughout the United States. Bronco Wine Company has become a major vintage varietal wine source to the California wine industry and is the largest vineyard owner in the United States. Our quest for quality begins with vineyard development and continues to grow into areas such as brand marketing and national distribution, brand development, research and development and premium bulk wine contracts. Bronco Wine Company is vertically integrated, from the vineyard to the table, focused on crafting wines for the American table.
