Protected Origin
Prosecco, Cava, Franciacorta: How Sparkling Wine Names Are Protected
Prosecco, Cava, Champagne, and Franciacorta are protected designations of origin within the EU: only wine from the defined region, produced according to the rules of its product specification, may bear the name. Even allusions using terms like "style" or "method" are prohibited. AOC, DOC, DOCG, and DO are the national seals.
What Does PDO Mean for Sparkling Wine?
Behind every great sparkling wine name stands a document that almost no buyer ever reads. The product specification defines where the grapes may grow, which varieties are permitted, and how the wine is pressed, fermented, and aged. Producers who comply with these rules and submit to inspection are allowed to use the name. The EU groups all of this under the term protected designation of origin, or PDO. Member states use their own abbreviations for this: AOC in France, DOC and DOCG in Italy, DO in Spain, Sekt b.A. in Germany, and Sekt g.U. in Austria.
The protection runs deep. EU market regulations don't just forbid using the name for wines from elsewhere—they also ban imitations and allusions. This holds true even if the true origin is stated, or if the name is paired with words like "style," "type," "method," or "imitation." A sparkling wine "in the style of Prosecco" or "Champagne-style" is therefore not permitted. Just how strict this is becomes clear from the ban on the term méthode champenoise, as we'll see at the fifth stop.
The Glera Case: Why Prosecco Is No Longer a Grape Variety
Until 2009, the main grape of Prosecco was itself called Prosecco. This was a problem, since grape variety names are free for anyone to use. Any producer in the world could have planted Prosecco vines and put the name on their label. Italy therefore pulled the emergency brake: through a ministerial decree dated July 17, 2009, effective January 1, 2010, the grape variety was renamed Glera throughout the EU. Since then, Prosecco has referred solely to a protected designation of origin.
To anchor the name to a specific place, the village of Prosecco near Trieste was included in the designated area, even though it lies far to the east of the hills of Conegliano and Valdobbiadene. Today the DOC spans nine provinces across Veneto and Friuli-Venezia Giulia and requires a minimum of 85% Glera. Above this sit two DOCGs: Conegliano Valdobbiadene, a DOC since 1969 and DOCG since 2009, and Asolo. The case is considered a textbook example of how a region can detach its name from that of a grape variety.
Cava and Franciacorta: Names That Also Guarantee a Method
Some designations of origin guarantee the production method as well. Cava was reserved as a name in Spain by ministerial decree on February 27, 1986, with the regulation following on November 14, 1991. Every Cava is produced through traditional bottle fermentation. Unusually, this designation of origin isn't tied to a single landscape. While around 95% comes from the area around Barcelona, since the 2020 zoning update the designation also covers areas in the Ebro Valley and Extremadura.
Franciacorta, on Lake Iseo in Lombardy, became a DOC in 1967 and a DOCG in 1995, restricted to sparkling wine made through bottle fermentation with at least 18 months on the lees. Since August 1, 2003, the DOCG abbreviation doesn't even need to appear on the label anymore. The name Franciacorta alone serves as the guarantee, much like Champagne. Both show how a place of origin can become so well-known that its name alone signifies location, method, and minimum aging all at once.
Champagne: The Oldest Fight Over a Sparkling Wine Name
No sparkling wine has defended its name as long as Champagne. The first joint lawsuits by producers date back to 1843; the law of May 6, 1919 delineated the region, and in 1936 the AOC was established by decree. Since 1941, the Comité Champagne has watched over the name and pursued cases of misuse. Germany, too, had to comply: following the Treaty of Versailles, German wineries were no longer allowed to call their sparkling wines Champagner, and the word Sekt finally took hold instead.
For buyers, protection of origin is above all a reading aid. If a protected name appears on the bottle, a verified set of rules applies—even if the label doesn't spell out the details. If it's absent, look instead at the category, the origin statement, and the method. The same technique and the same grape varieties can produce excellent sparkling wines elsewhere—they just can't carry the protected name.
