The fruit is crushed and destemmed, and fermented in concrete, for between three and six weeks, dependant on the wine and the season. Maturation is in a traditional wooden botti of 1600 litres capacity. A long maturation between two and three years is required to allow the tannin to soften, and the intense, bright fruit to deepen, and allow some of the secondary, more subtle aromas and flavours to shine through.
