Argiano established their Montalcino vineyards with a priority to determine the most favourable aspects and climes. Harvest normally begins around the end of September as the earlier ripening Syrah and Merlot are brought to the Argiano wineworks, followed in October by the later cropping Cabernet and Sangiovese. Each of four different varieties are separately vinified to preserve their individual characteristics. Upon completion of ferments, the wines are put to second use French oak barriques and traditional large Slovenian casks for several months maturation, softening the tannins and integrating the fruit, before the final assemblage of 40% Cabernet Sauvignon and equal parts Sangiovese, Merlot and Syrah.
