<P> Chianti Classico wines are characterised in their youth by their predominantly floral and cinnamon spicy bouquet . As the wine ages, aromas of tobacco and leather can emerge . Chiantis tend to have medium - high acidity and medium tannins . The acidity in the wines make them very flexible with food and wine pairings, particularly with Italian cuisines that feature red sauce, as well as with beef, lamb and game . Basic level Chianti is often characterised by its juicy fruit notes of cherry, plum and raspberry and can range from simple quaffing wines to those approaching the level of Chianti Classico . Wine expert Tom Stevenson notes that these basic everyday - drinking Chiantis are at their peak drinking qualities often between three and five years after vintage with premium examples having the potential to age for four to eight years . Well - made examples of Chianti Classico often have the potential to age and improve in the bottle for six to twenty years . </P> <P> Chianti Superiore is an Italian DOCG wine produced in the provinces of Arezzo, Florence, Pisa, Pistoia, Prato and Siena, in Tuscany . Superiore is a specification for wines produced with a stricter rule of production than other Chianti wines . Chianti Superiore has been authorised since 1996 . Chianti Superiore wines can be produced only from grapes cultivated in the Chianti wine areas except from those vineyards that are registered in the Chianti Classico sub-zone . Vineyards registered in Chianti sub-zones other than Classico can produce Chianti Superiore wines but must omit the sub-zone name on the label . Aging is calculated from 1 January after the picking . Chianti Superiore cannot be sold to the consumer before nine months of aging, of which three must be in the bottle . Therefore, it cannot be bottled before the June after picking or sold to consumers before the next September . </P> <Table> <Tr> <Th_colspan="4"> 2004 production </Th> </Tr> <Tr> <Th> </Th> <Th> Chianti Superiore </Th> <Th> Other Chianti </Th> <Th>% Ch .
