São João wineries are an independent family business. Founded in 1920, these wineries are preparing their 100th anniversary. This company has always been associated with avant-garde and tradition. In 1930 this company started to sell sparkling wine and in 1959 started to market high-quality bottled wines, both at national and international levels. Inspired in the past, this company reintroduced the universal varieties in Quinta do Poço do Lobo, bought in 1971. It is impossible to write the history of the production of Bairrada wine without mentioning São João wineries.
