"At Ridge, we call our approach to winemaking “pre-industrial.” We believe that for anyone attempting to make fine wine, modern additives and industrial processing limit true quality. Our philosophy comes from the techniques used in the finest 19th-century California wineries and Bordeaux chateaux. In 1933, after thirteen years of Prohibition, very few winemakers who were trained in pre-Prohibition traditional techniques were young enough to return to their positions. Universities stepped in to fill the need for winemaker expertise, and began – year by year – to reinvent winemaking as an industrial process. We believe that these increasingly industrial methods interfere with the distinctive qualities of a fine vineyard and mask – rather than improve – the character of a wine." Ridge Vineyards
