Since 1978 Monfortino has been sourced exclusively from the Cascina Francia vineyard (acquired by Giovanni Conterno in 1974). Monfortino represents a selection of the best grapes in the greatest years, but it is also made differently. It undergoes an uncontrolled fermentation at relatively high temperatures. On average, Monfortino also remains an additional three years longer in large oak casks (botti). That extra aging in cask attributes the extraordinary structure, power and concentration of the wine.
