A trip to Tuscany inevitably means a glass of red Chianti Classico for most visitors. But what makes this wine special? Chianti Classico must come from grapes grown in a strictly defined area of the hills between Florence and Siena, centered around Castellina, Gaiole, Radda and Greve: The original boundaries were laid down in 1716 by Cosimo III di Medici, Grand Duke of Tuscany, and covered the Tuscan villages of Castellina, Gaiole and Radda. In 1932, Chianti was vastly expanded to cover seven different regions of which the original area was just one. Today, the area is roughly 100 square miles. There are also rules on the grape content that have changed over the years. Since the 1990s, Chianti Classico has to contain at least 75% Sangiovese grapes, a maximum of 10% Canaiolo, at most 6% white wine grapes and up to 15% Cabernet, Merlot or Syrah.
For many, Tuscan wine means Chianti -- but Super Tuscan wines have been growing strongly in popularity, and increasingly appear on US wine lists. So what is a Super Tuscan, anyway? Super Tuscans started out as high quality wines from Tuscany that didn't fit into the strict definition of Chianti wine according to the Italian authorities. The first Super Tuscan was Tignanello from Antinori, produced in 1971. It was a “Chianti-style” blend of Sangiovese and Cabernet, but it didn't fit the DOCG definition of Chianti at the time (which didn’t allow Cabernet and required at least 10% white wine grapes). Antinori wanted to maximize the potential of the grapes and wine-making in Tuscany without being constrained to a specific formula. He also broke with tradition in aging the wine in French barriques (oak barrels from Bordeaux) rather than the traditional Slovenian oak or Chestnut used for Chianti. The wine began to win awards and acclaim, prices rose and other producers followed, and so “Super Tuscan” wines as a category were born. The success of Super Tuscans led the Italian authorities to change the rules of grape composition in the 1990s, allowing many Super Tuscans to be classified as true Chianti Classico. Today, Super Tuscans that still don't fit the Chianti rules are classified as IGT (Indicazione Geografica Tipica), "typical of the geography". Prices for Super Tuscans range from the very reasonably to the stratospheric. Some of the best known include Tignananello (still a major force), Sassacaia from Tenuta San Guido, Solaia from Antinori and Ornellaia from Tenuta della Ornellaia.
