Italy is home to some of the oldest wine-producing regions in the world, and Italian wines are known worldwide for their broad variety. Italy is the world’s largest wine producer by volume. Its contribution is about 45–50 million hl per year, and represents about 1/3 of global production. Italian wine is exported around the world and is also extremely popular in Italy: Italians rank fifth on the world wine consumption list by volume with 42 liters per capita consumption. Grapes are grown in almost every region of the country and there are more than one million vineyards under cultivation.
Italian appellation system
In 1963, the first official Italian system of classification of wines was launched. Since then, several modifications and additions to the legislation have been made (a major one in 1992), the last of which, in 2010, has established four basic categories, which are consistent with the last EU regulation in matter of wine (2008-09). The categories, from the bottom level to the top one, are:
Vini (Wines - informally called 'generic wines'): These are wines that can be produced anywhere in the territory of the EU; no indication of geographical origin, of the grape varieties used, or of the vintage is allowed on the label. (The label only reports the color of the wine.)
Vini Varietali (Varietal Wines): These are generic wines that are made either mostly (at least 85%) from one kind of authorized 'international' grapes (Cabernet Franc, Cabernet Sauvignon, Chardonnay, Merlot, Sauvignon blanc, Syrah) or entirely from two or more of them. The grape(s) and the vintage can be indicated on the label. (The prohibition to indicate the geographical origin is instead maintained. These wines can be produced anywhere in the territory of the EU.)
Vini IGP (Wines with Protected Geographical Indication): This category (also traditionally implemented in Italy as IGT - Typical Geographical Indication) is reserved to wines produced in a specific territory within Italy and following a series of specific and precise regulations on authorized varieties, viticultural and vinification practices, organoleptic and chemico-physical characteristics, labeling instructions, etc. Currently (2014) there exist 118 IGPs/IGTs.
Vini DOP (Wines with Protected Designation of Origin): This category includes two sub-categories, i.e. Vini DOC (Controlled Designation of Origin) and Vini DOCG (Controlled and Guaranteed Designation of Origin). DOC wines must have been IGP wines for at least 5 years. They generally come from smaller regions, within a certain IGP territory, that are particularly vocated for their climatic and geological characteristics and for the quality and originality of the local winemaking traditions. They also must follow stricter production regulations than IGP wines. A DOC wine can be promoted to DOCG if it has been a DOC for at least 10 years. In addition to fulfilling the requisites for DOC wines (since that's the category they come from), before commercialization DOCG wines must pass stricter analyses, including a tasting by a specifically appointed committee. DOCG wines have also demonstrated a superior commercial success. Currently (2014) there exist 332 DOCs and 73 DOCGs for a total of 405 DOPs.
A number of sub-categories also exist regulating the production of sparkling wines (e.g. Vino Spumante, Vino Spumante di Qualità, Vino Spumante di Qualità di Tipo Aromatico, Vino Frizzante).
Important wine-relevant geographic characteristics of Italy include the extensive latitudinal range of the country permits wine growing from the Alps in the north to almost-within-sight of Africa in the south. The fact that Italy is a peninsula with a long shoreline contributes moderating climate to coastal wine regions. The extensive mountains and foothills provide many altitudes for grape growing and a variety of climate and soil conditions.
Italian Wine Regions
Italy's twenty wine regions correspond to the twenty administrative regions. Understanding of Italian wine becomes clearer with an understanding of the differences between each region; their cuisines reflect their indigenous wines, and vice-versa.
The 73 DOCG wines are located in 15 different regions but most of them are concentrated in Piedmont, Veneto and Tuscany. Among these are appellations appreciated and sought after by wine lovers around the world: Barolo, Barbaresco, and Brunello di Montalcino (colloquially known as the "Killer B's").
Other notable wines that in the latest years gain much attention in the international markets and among specialists are: Amarone della Valpolicella, Prosecco di Conegliano- Valdobbiadene, Taurasi from Campania, Franciacorta sparkling wines from Lombardy; evergreen wines are Chianti and Soave, while new wines from the Centre and South of Italy are quickly gaining recognition: Sagrantino, Primitivo, Nero D'Avola among others. The Friuli-Venezia Giulia is world famous for the quality of her white wines, like Pinot Grigio. Special sweet wines like Passitos and Moscatos, made in different regions, are also famous since old time.
