The Denominazione di Origine Controllata (DOC) system was introduced in 1963 as a means of formalizing and protecting Italian wine appellations.
The French AOC system acted as a model for Italian authorities, as they established maximum yields, approved varieties and viticultural practices, set geographical boundaries, and authorized vinification techniques, styles, and minimum (or maximum) alcohol levels for each DOC wine. The Denominazione di Origine Controllata e Garantita (DOCG) category, a more prestigious and—theoretically—higher quality designation designed to represent the best of Italian wine, was also introduced in 1963, although the first DOCG was not awarded until 1980, when Brunello di Montalcino, Barolo and Vino Nobile di Montepulciano were upgraded from DOC. Most DOCGs (and many DOCs) stipulate minimum aging requirements for the wines—a notable departure from the legal requirements set by most French appellations. Over time, the system became unwieldy and too lenient; yields and geographical restrictions became too generous. Hundreds of DOC zones were established, leading to consumer confusion. Even the DOCG category, which should only include the recognizable benchmarks of Italian wine, was watered down by such unlikely promotions as Romagna Albana. As criticism of the system amplified in the 1970s and 1980s, many of Italy’s finer producers resorted to the Vino da Tavola category, releasing experimental wines produced in a manner conflicting with DOC legislation. Vino da Tavola, or table wine, cannot bear any geographical designation other than “Italy” itself, yet some of Italy’s most iconic wines—in particular the “Super Tuscans” Sassicaia and Tignanello—got their start as simple Vino da Tavola.
We can update most recent DOCG to Cannelli (77 for Italy, 19 for Piemonte) and also could nuance the discussion of Terrano vs Refosco, as in the guide it is stated that they are not identical which is not quite accurate. Refosco is a family of closely related grapes, and Terrano is indeed "genetically identical" to a member of the Refosco family
Hey Mark! We are still waiting for Canelli to be registered by the EU. It is currently in the midst of review. It was published, on 2/6/23 and now has a three-month long period for possible opposition. After that, it will then be up for registration. If registered we will update everything! In regards to Terrano/Refosco, the guide is updated with a little extra nuance. Thanks!
