Chianti Classico

Chianti Classico is a red-wine denomination in the hills between Florence and Siena in Tuscany. Sangiovese supplies its foundation, bringing acidity and tannin to wines whose weight and ripeness vary across the region's elevations, exposures, and soils.

Chianti Classico and Chianti are separate denominations with distinct production zones and rules. The word Classico identifies the historic central territory, whose wines carry the black-rooster emblem. It is useful to keep that geographical distinction separate from the maturation categories found on a Chianti Classico label.

A landscape of differing slopes

Vineyards occupy a hilly landscape interspersed with woods, olive groves, and villages. The production area includes Castellina, Gaiole, Greve, and Radda in Chianti, together with parts of several neighbouring communes. Its many aspects expose vines to different amounts and times of sunlight.

Elevation and exposure influence the pace of Sangiovese's long ripening season. Cooler sites can preserve acidity while requiring more time to ripen the skins and seeds. Warmer slopes can accumulate sugar more readily, with harvest decisions determining the balance between alcohol, fruit, and tannin. Vintage weather can change the advantages of a particular site.

The geological vocabulary includes alberese, a limestone-rich material, and galestro, a flaky, clay-rich rock. Sandstone, sand, and other deposits also occur. Their practical importance lies in differences in soil depth, rooting conditions, drainage, and water supply. A commune can contain several such environments, so its name gives a starting point for understanding a wine's origin.

Grapes and cellar choices

The specification consolidated on 22 June 2023 requires ordinary Chianti Classico and Riserva to contain 80–100% Sangiovese. The remainder may come from authorized red varieties. This permits both pure Sangiovese and blends with grapes such as Canaiolo, Colorino, Merlot, or Cabernet Sauvignon.1.

Article 2 provides a five-harvest transition for the new Gran Selezione blend.

The proportions can change the wine's colour, tannin, and fruit profile. Extraction during fermentation then determines how much material passes from the grape skins and seeds into the wine. Oak maturation offers another source of variation. Large, established casks generally contribute less fresh wood aroma per litre than small new barrels. Producers can combine vessels and maturation periods according to the wine they want to make.

Maturation categories and place names

Ordinary Chianti Classico may be released from 1 October following the harvest. Riserva requires at least 24 months' ageing, including three months in bottle. Gran Selezione requires 30 months, also including three in bottle, and grapes from vineyards farmed by the bottling estate. The ageing clock for Riserva and Gran Selezione begins on 1 January after harvest.1.

Article 2 provides a five-harvest transition for the new Gran Selezione blend.

The 2023 revision also established additional geographical units, or UGAs, for Gran Selezione. Names such as Radda, Panzano, and Lamole locate the fruit more closely within the denomination. These are areas of origin, each capable of containing more than one vineyard and wine style.

A further change raises Gran Selezione's minimum Sangiovese proportion to 90% and limits the remainder to specified local red varieties. It takes effect with the 2027 harvest. Earlier vintages can therefore legitimately follow the previous blending rules.1.
