The 14th May 1924, a group of wine producer of the Chianti area convened an assembly in order to create a volunteer organisation to difend and to enhance theyr own wine production.It was founded the "Union for the Defence of the typical wine production and of its brand-of-provenance",this definition changed many times and today it is called "Union of historical brand - Chianti Classico" and is featured, since always, by the picture of a black rooster.
In 1924 the union had only 33 members, today they are more than 600 (270 of which produce and use a personal wine-label) and produce more than 80% of the whole Chianti Classico. It is a union which involes both small- medium- big producers of wine and wine growers´ cooperatives together with wineries; the respect of laws that the union dictates is their force.
