Oeuf de Beaune
Many of the world's finest wines are made in concrete tanks. Concrete fermenters have been used widely in Europe for many years. Concrete "breathes" like oak. It is semi-permeable which concentrates the wine, while gently diffusing oxygen without adding oak character. Concrete provides the benefits of oak and the efficiency of stainless while producing a fine wine. Today, some of the finest wines in America are being fermented and stored in concrete tanks.
