Tuscany
The home of Sangiovese. Where Chianti was reinvented, Brunello rediscovered, and a handful of producers quietly decided Italian wine law was getting in the way of great wine.
Tuscany (Toscana) is a wine region in central Italy, in the Tuscany administrative region, producing approximately 2.9 million hectolitres of wine annually — the second largest regional wine production in Italy by volume. The region contains 11 DOCG designations and 41 DOC designations. The dominant grape is Sangiovese, which is the sole or primary variety in Chianti Classico DOCG, Brunello di Montalcino DOCG, Vino Nobile di Montepulciano DOCG, Morellino di Scansano DOCG, and many others. The most commercially significant DOCGs are Chianti Classico (approximately 7,200 ha, between Florence and Siena), Brunello di Montalcino (approximately 3,500 ha, around Montalcino in the Val d'Orcia), and Vernaccia di San Gimignano (the first DOC granted in Italy, 1966; the first white wine DOCG). The Bolgheri DOC is also significant as the legal framework within which Sassicaia, Ornellaia, and other internationally influential blends based on Cabernet Sauvignon and Merlot are produced.
Sangiovese — Italy's most planted and most versatile grape
Sangiovese is Italy's most widely planted red variety and produces an enormous range of styles depending on where it is grown, how it is grown, and what the winemaker does with it. In the hills of Chianti Classico, it produces wines of medium body, cherry fruit, and high acidity. In Montalcino, as Brunello (a local biotype), it produces wines of exceptional tannic intensity, minerality, and ageability. On the Maremma coast as Morellino di Scansano, it produces softer, more fruit-forward wines. The same variety, the same name, completely different results — which is why Sangiovese is simultaneously the basis for Italy's most widely exported everyday wines and its most collectible, expensive bottles.
Sangiovese's defining characteristics are high natural acidity (typical pH 3.2–3.4, titratable acidity 5.5–7.5 g/L as tartaric), relatively light to medium colour (less anthocyanin than Cabernet Sauvignon or Syrah), and a cherry/sour cherry fruit profile overlaid with dried herbs, leather, and earthy notes in more complex expressions.
The Super Tuscan phenomenon — when producers broke the law to make better wine
In the 1970s, several ambitious Tuscan producers became frustrated with the restrictions of Italian wine law. The Chianti DOC rules at the time (under the 1967 Torgiano regulations) required producers to include white grapes (Trebbiano and Malvasia) in Chianti blends — which diluted the red wine character and made ambitious quality unachievable within the DOC framework. Sassicaia (first commercial vintage 1968, produced by Mario Incisa della Rocchetta) was a Cabernet Sauvignon-dominant blend entirely outside any DOC — it was originally sold as Vino da Tavola (table wine), the lowest classification, because it didn't comply with any local DOC rules.
The commercial and critical success of Sassicaia and similar wines (Tignanello — Antinori's Sangiovese-Cabernet blend, first 1971; Ornellaia; Masseto pure Merlot) created a category — the "Super Tuscans" — that was formally sold at higher prices than the region's DOCGs, despite having a lower legal classification. The Italian wine regulatory system eventually adapted: Bolgheri DOC now accommodates the style; Chianti Classico reformed to remove the mandatory white grape requirement; and IGT Toscana provides a framework for wines outside the DOC/DOCG restrictions.
Key Tuscan DOCGs and DOCs — documented specifications

Galestro and Alberese — Tuscany's defining soils
The Chianti Classico zone and the hills around Montalcino are characterised by two specific soil types that are documented as central to the character of Tuscan wines:
Galestro — a friable, flaky schist-limestone rock that crumbles easily and drains rapidly. It has low nutrient content, forcing vine roots to penetrate deeply and reducing yields. Wines from galestro-dominant soils tend toward elegance, mineral definition, and high acidity. Galestro is found throughout the Chianti Classico zone, particularly in the higher-altitude central part of the appellation.
Alberese — a harder, denser clay-limestone with higher fertility and water retention. Produces more structured, full-bodied wines with more tannic weight. Found in parts of Chianti Classico and in the lower-altitude areas of the Montalcino zone.
Sangiovese tannin chemistry — why it ages differently from Nebbiolo
Sangiovese and Nebbiolo are both high-acid, high-tannin Italian red wine grapes, but their tannin chemistry differs in important ways that explain their different sensory profiles and ageing trajectories.
Nebbiolo's tannins are dominated by procyanidins (catechin + epicatechin polymers) with high average polymerisation — producing the coarse, gritty tannin that Barolo is known for in youth. Sangiovese's tannins have a different composition — higher ratio of galloylated proanthocyanidins (with gallic acid esterification on the polymer chain), which makes them perceptually drier but less coarsely astringent than Nebbiolo tannins. Galloylation increases the tannin's tendency to bind and precipitate salivary proteins — explaining the characteristic dry, coating tannic sensation of Chianti Classico relative to the harsh grittiness of young Barolo.
Both varieties have high total anthocyanin content when young, but Sangiovese's anthocyanins are more stable than Nebbiolo's — Sangiovese retains its ruby colour for longer. A 10-year-old Sangiovese typically shows less orange-brick tinting than a 10-year-old Nebbiolo from the same vintage. This difference reflects the different anthocyanin profiles: Nebbiolo contains predominantly malvidin-3-glucoside but with low cofactor concentration, making its colour unstable; Sangiovese's anthocyanin polymerises more efficiently with tannins during ageing. Source: Baldi et al. (2020) documented differences in anthocyanin stability between Sangiovese and Nebbiolo.
The evolution of Chianti Classico regulations — documented reform history
The regulatory history of Chianti is one of the most significant stories in Italian wine law. The original Chianti zone was defined by Baron Ricasoli in the 1870s as a blend of Sangiovese, Canaiolo, Trebbiano, and Malvasia — the white varieties were included because they softened and stabilised the wine for early drinking. The 1967 DOC decree codified this blend, requiring up to 30% white grapes in Chianti. The commercial consequence was a flood of dilute, pale Chianti in wicker-covered flasks that became internationally associated with cheap Italian restaurant wine.
The 1984 DOCG conversion began reform: white grape percentages were reduced. The creation of Chianti Classico as a separate entity (distinguishing the historic original zone between Florence and Siena from the expanded Chianti DOC zone) was formalised in 1996. The 1996 Chianti Classico DOCG disciplinare progressively removed the white grape requirement and raised the minimum Sangiovese content. The Gran Selezione tier was established in 2014 as the highest tier. The result: Chianti Classico is now a completely different wine from the fiasco Chianti of the 1960s–1980s, though both share the same name and the same geographic origin.
