Carlo Marchi bought the winery in 1933, and the estate is situated in the heart of the Chianti Classico area and extends over 390 hectares of land. Only 20 hectares are planted with vines and another 100 hectares with olive trees. The winery belongs to the Marchesi di Frescobaldi family, one of the most famous wine-producing families in Italy, to which the Tenuta di Ornellaia also belongs. However, Collazzi is managed independently of the group and can therefore commit itself without exception to a sustainable quality philosophy. Great importance is attached to careful and selective work in the vineyard, the harvest is done by hand.
