Trademark of the Consorzio del Marchio Storico Chianti Classico (Consortium of the historic Chianti Classico brand), founded in 1924. At that time there were 33 members who have grown to over 600 to date. These generate around 80% of the Chianti Classico, The "Black Rooster" is the historical symbol of the "Lega militare del Chianti", a type of military federation of the Chiantis that ruled in this territory from the 14th century. According to legend, a black rooster also played an important role in defining the geographical boundaries of the Chianti, The Medici court painter Giorgio Vasari (1511-1574) painted the black rooster as an allegory of the Chianti-Classico on the ceiling of the Salone dei Cinquecento in the Florentine Palazzo Vecchio.
The Chianti protection association previously bore the name "Consorzio del Gallo Nero", but the Californian wine multinational complained about the part of the name "Gallo Nero" Gallo for themselves. After a long legal dispute, it was decided in 2005 that the name "Gallo Nero" and the black rooster in combination outside of Italy may no longer be used by the protection consortium. Therefore, the change had to be made to the name given above. The second association "Vino Chianti Classico" agreed with the Consorzio in 2005 after an 18 year long dispute. A common marketing concept was developed. Now all the wines from the Chianti Classico region have the Gallo-nero symbol next to the pink DOCG band. Marco Pallanti from has been President of the Chianti Classico Consortium since the end of 2006 Castello di Ama,
