In 1915, the brothers Bach i Escopet, Pere and Ramón, moved to Sant Esteve Sesrovires from Barcelona and acquired an 18th-century estate called Can Estrada. Thanks to the profits obtained from the cotton trade, the brothers were able to invest in setting up the winery, which gradually grew with the purchase of new estates, reaching a total area of 365 hectares. The 1920 harvest, based on Xarello and Macabeo, marked the debut of Bach.
The Spanish Civil War disrupted part of the splendor achieved by Bach in the 1920s and had tragic consequences for the family: Ramón died, and his brother Pere, although he survived the conflict, was deeply affected by its memory. A few years later, in 1942, he decided to sell the estate. In the following years, Bach had several owners until, in 1975, the Raventós family acquired the estate and integrated Bach into their group of wineries.
