The Castello di Brolio Vin Santo, true to tradition, expresses one of the "historic" grapes of the area, Malvasia del Chianti. Its production method also stays true to tradition.
Notes on the method of production

The grapes destined for Vin Santo are gathered late in the harvest, at the point at which the sugar content is high enough to sustain the long ageing process that this wine undergoes. The bunches are hung and left to dry partially for several months. The must obtained from light crushing ferments slowly and is then placed in 225-litre half-barriques of oak.
