The craftsmen of Manetti Gusmano e Figli produce the classic wine-making jars using the technique of “lavoro fondato”, inspired by and very similar to that of the “colombino” or “lucignolo”. But what makes these jars even more special is the uniqueness of the clay; in the Chianti Classico terroir, the abundant presence of Galestro gives the terracotta special chromatic characteristics and resistance to cold. Among the natural components that make up the clay, calcium salts and carbonates give the product permeability and porosity characteristics that are particularly important for terracotta vessels. All these characteristics, together with their antioxidant action and high thermal capacity, make Gusmano Manetti e Figli terracotta jars an ideal tool for the production of great wines.
