The Badia a Passignano vineyards near Sambuca Val di Pesa are planted to the best Sangiovese clones taken from very old vineyards at Tignanello. After destemming and a soft crush, grapes are treated to a maceration where indigenous yeasts activate fermentation. After a delicate pumpover and delestage, the fermented must remains on skins for a fortnight. At the end of year, batches spontaneously complete malolactic in a selection of new and seasoned French and Hungarian oak barriques. Component wines are then assembled and returned to barriques for a year's ageing. Barrels are then sampled before the finest are bottled under the Badia di Passignano label and aged for a further year.
