Since 1978, both Barolos—Monfortino and Cascina Francia—have been sourced exclusively from Cascina Francia. Monfortino represents, of course, a selection of the best grapes in the greatest years. But it also made differently, first undergoing an uncontrolled fermentation at relatively high temperatures. On average, Monfortino also remains an additional three years longer in large oak casks (botti). Monfortino’s extra aging in cask, says Roberto, is a consequence of the extraordinary structure, power and concentration of the wine.
