Every year, wineries in Chianti Classico release their newest wines, which rather than being one homogeneous vintage are always represented by a range of different vintages.

This is partly dictated by regulations (for example, Chianti Classico Riserva and Gran Selezione require more ageing before they can be released) but is also a matter of choice which varies from winery to winery, with some choosing to age their wines for extended periods before releasing them onto the market.
