Chianti is the sub-region of Tuscany located between Florence to the north and Siena to the south. Wine made within the eight historical zones is labelled Chianti Classico and must be made with a minimum 80% Sangiovese and is often topped up with Canaiolo, Merlot, and Cabernet Sauvignon as well as two white grapes, Trebbiano and Malvasia. With its many small, picturesque rolling hills, aspect and soil types vary significantly, even within a single estate. Any wine made by a member of the Consorzio (wine-growers association) is bottled wearing the recognizable black rooster "Gallo Nero" seal around the neck of the bottle.
