The cellars underneath the estate Villa remain the most precious jewel of Argiano. It's here, that since the sixteenth century, the wines can fine at constant temperature and humidity, in complete absence of light and noise. The maturation takes place in a selection of the finest coopered small and medium size casks to achieve a more subtle and balanced tannin extraction. The choice of oak is of fundamental importance and is in constant evolution. Cabernet, Merlot and Syrah are hand harvested into small baskets. Varietals are separately handled, macerated for a fortnight or more, fermented and treated to malolactic before transfer to a selection of completely new French oak barriques for up to seventeen months maturation.
