Stainless steel tanks were first advocated by Emile Peynaud during the early 1960s. He observed their success in the dairy industry and thought that they could revolutionize winemaking as well. Chateau Haut Brion was listening to Peynaud. In 1961, this legendary Bordeaux producer was one of the first wineries in the world to install stainless steel tanks. Because of the benefits these fermentation containers offer, it was not long until many other wineries followed suit.
