Prosecco Hills, Franciacorta and Langhe: What the Numbers Say About Italy's Wine Landscapes

Three landscapes, two inscriptions

Both Prosecco and Langhe-Roero are World Heritage cultural landscapes. They sit on the same list as the historic centre of Rome and the Dolomites, under the 1972 World Heritage Convention. They are separate from the intangible heritage list, which is the programme that covers practices such as Italian cooking. The distinction matters because the cultural-landscape listing protects a physical territory with fixed boundaries. Those boundaries define the area that any "UNESCO effect" study should be measuring.

The Prosecco Hills took two attempts. The World Heritage Committee referred the first nomination back to Italy in 2018 under Decision 42 COM 8B.31. A revised file was inscribed on 7 July 2019 in Baku, under Decision 43 COM 8B.37, on criterion (v), which covers traditional land use. The advisory body ICOMOS gave the revised property an area of 9,197.45 hectares and a buffer zone of 9,769.80 hectares. Veneto's announcement on the day said the core zone includes 12 municipalities and the buffer zone involves 3 more. That explains the figure of 15 municipalities sometimes given for the site. The inscribed core itself covers 12.

Langhe-Roero and Monferrato was inscribed five years earlier, on 22 June 2014 in Doha, under Decision 38 COM 8B.41. An earlier nomination had been deferred in 2012. The property meets criteria (iii) and (v). The ICOMOS evaluation lists component parts totalling 10,789 hectares, with a buffer zone of 76,249 hectares. The Piedmont regional government counts 29 municipalities in the site and 101 in the wider protected area. It names six components: the Langa of Barolo, the hills of Barbaresco, Nizza Monferrato and Barbera, Canelli and Asti Spumante, the Monferrato of the Infernot cellars, and the Castle of Grinzane Cavour. UNESCO's own summary describes five wine-growing areas plus the castle. Both descriptions refer to the same property.

Franciacorta does not appear on the World Heritage List. Its consortium describes a territory of 20,370 hectares across 19 municipalities, of which 3,634 hectares are planted with vines. That is about 17.8% of the land, by the consortium's own calculation.

The buffer zones explain much of the confusion about size. The Langhe-Roero buffer is seven times the core. Prosecco's buffer is about the same size as its core. Any figure presented as "the UNESCO area" should say whether it means the core, the buffer, or something wider such as a wine denomination or a tourist district.

How big are they as wine regions?

On wine volume the three are not in the same league. The Consorzio Prosecco DOC reported 667 million bottles in 2025, up 1.1% on 2024. That total combines 606,891,509 bottles of Prosecco DOC and 60,360,239 of Prosecco DOC Rosé. The DOC is a large denomination across Veneto and Friuli Venezia Giulia. In 2023 the Treviso-Belluno chamber of commerce put its vineyard at more than 28,100 hectares, roughly three times the UNESCO core. Most of the DOC's vineyard therefore lies outside the World Heritage hills, since the DOC vineyard alone is larger than the whole inscribed core.

The wine of the hills themselves is Conegliano Valdobbiadene Prosecco Superiore DOCG. The Treviso-Belluno chamber of commerce recorded 8,653 hectares and more than 92.4 million bottles produced in 2023 across a 15-municipality denomination. For 2025 the consortium president, Franco Adami, told the trade press that sales reached about 98 million bottles, up about 8%. We read that figure only in news reports, and it was described at the time as the consortium's own count.

Franciacorta is a much smaller wine. Its consortium estimates 18,932,034 equivalent bottles sold in 2025, down 1.0% on the 19,128,814 of 2024. The estimate rests on an observatory that covers 83.4% of member companies. Exports were 12.8% of volume, up from 12.0% in 2024. Switzerland took 22.7% of exports, Japan 12.6% and the United States 12.2%. On these figures Prosecco DOC bottles outnumber Franciacorta bottles by roughly 35 to 1. That ratio is ours and compares bottled volume with estimated sales, so it is a rough guide only.

Langhe sits in between on volume. The Consorzio di Tutela Barolo Barbaresco Alba Langhe e Dogliani lists 10,000 hectares of vineyard, more than 500 members and 66 million bottles across nine denominations. The page is undated, and the totals cover all nine denominations together. We did not find a primary source giving hectares for Barolo alone.

Prosecco Hills: a growth rate without a base

The best official figure for the Prosecco Hills is the one in the opening paragraph. Veneto's press release of 13 February 2026 reported that the "area UNESCO del Prosecco di Conegliano e Valdobbiadene" saw arrivals rise 7.3% and nights rise 8.5% in 2025. The release labels the figures provisional until ISTAT publishes official data. The same release reported the Colli Euganei, another Veneto UNESCO area, at 3.2% more arrivals and 0.8% more nights.

Earlier in the year a partial figure circulated widely. In July 2025 the regional tourism councillor, Federico Caner, gave January to May growth of 2.7% in arrivals and 3.9% in nights for the same area, as reported by the news agency Italpress. The full-year rates are more than twice as high, so the partial figure now understates growth and should be cited only with its January-to-May label.

The province of Treviso, which contains the whole property, does have absolute data. The region's February 2026 statistical bulletin records 1,025,456 arrivals and 2,189,065 nights in the province in 2025. Arrivals rose 3.3% and nights rose 3.7%. Treviso's provincial total also includes the city of Treviso and many towns outside the hills. It cannot stand in for the hills. By our arithmetic the province accounted for about 3% of Veneto's 74,157,123 nights. Visitors in the province stayed an average of 2.13 nights per arrival.

What the two series show together is direction. The UNESCO area grew more than twice as fast as its province in 2025 on both arrivals and nights. The bulletin's regional tourist areas give some context. Veneto's mountain areas grew nights by 7.9%, its lakes by 0.3% and its art cities by 0.9%. The Prosecco Hills outpaced every one of those groups on nights. For the big lake destinations nearby, see our analysis of Lake Como and Lake Garda visitor statistics.

Two other numbers need care. Diego Tomasi, director of the Prosecco Superiore DOCG consortium, told Gambero Rosso in December 2025 that tourists rose 30% from January to August 2025, with 154,000 presences. He did not say which area, which accommodation types or which data source. A rise of 30% over eight months is hard to reconcile with the regional government's 8.5% for the full year. We treat it as an unverified statement. The same article reported preliminary results from a study by the UNESCO Chair at Unitelma Sapienza University in Rome, directed by Pier Luigi Petrillo. Gambero Rosso reported that, six years after inscription, accommodation facilities in the hills had grown 45.4% and beds 35.4%, against 3% and 8.2% in other prestigious European wine landscapes without UNESCO status. ANSA's English service reported the same 45.4% and 3% figures. We could not find the study itself online, so these remain figures reported in the press.

Langhe-Roero and Monferrato: the best-measured of the three

Piedmont publishes the most usable data of the three regions, though still at the wrong scope for the UNESCO core. The Cuneo chamber of commerce's annual Rapporto Cuneo uses data from the Piedmont regional tourism observatory. Its 2026 edition gives two separate series.

The first is the province of Cuneo. In 2025 the province recorded 993,982 arrivals and 2,326,624 nights, both up 10.7% on 2024. Foreign visitors made 401,092 of those arrivals, or 40.35%, and 1,067,496 of the nights, or 45.9%. France was the largest foreign market by arrivals with 77,816, followed by Switzerland with 66,091 and Germany with 50,778. The United States came fourth with 27,463 arrivals and 78,007 nights. Americans in this province are a small market in absolute terms. For the national picture see our analysis of American tourists in Italy in 2026. The provincial count covers hotels, other accommodation and, since 1 October 2019, private short-term rentals registered with the region.

The second series is the official tourist district, the ATL Langhe Monferrato Roero. In 2025 it recorded 761,274 arrivals, up 9.6%, and 1,731,116 nights, up 11.9%. Italians accounted for 38.6% of nights, so foreign visitors accounted for the majority, at 61.4% by our subtraction. The district's own release for 2024, as reprinted by the local news site Cuneodice and labelled provisional, gave 694,282 arrivals and 1,547,536 nights, a rise of 5.2% in nights on 2023. That release also showed the United Kingdom down 12.4% and the Netherlands up 24.9%.

The two series overlap but differ. The ATL extends into the province of Asti, while the province of Cuneo also includes Alpine valleys and the city of Cuneo, which lie outside the district. Neither matches the 29 municipalities of the UNESCO site. The figures should never be added together or presented as one series. Average stays are similar in both: 2.34 nights per arrival in the province and 2.27 in the ATL, by our calculation. Both are close to the 2.13 we calculate for the province of Treviso.

Even the best-measured wine landscape therefore has a short-stay pattern, at about 2.3 nights per arrival in both series. The 2024 district figures also travel under the wrong label. Gambero Rosso, in December 2025, gave more than 690,000 arrivals and 1.5 million nights in 2024 for the Langhe-Roero and Monferrato wine landscapes. Those totals match the tourist district's release, which covers a wider area than the 29 UNESCO municipalities. Turin is the nearest large city, and our Turin travel guide covers it.

Franciacorta: a famous wine with no tourism series of its own

Franciacorta is the hardest of the three to measure. It is a recognized wine district with a consortium, a wine route and an annual cellar festival. It is not an official tourist district, and Lombardy does not publish a series for its 19 municipalities that we could find.

The Franciacorta consortium's own anniversary page quotes tourism figures. It says visitors grew from 1.8 million in 2008 to 3 million in 2023, and that stay-days rose from 7.9 million to 10.6 million, after a peak of 11.3 million in 2022. These figures refer to the province of Brescia. That province includes the western shore of Lake Garda, the Brescian side of Lake Iseo, the Alpine Valcamonica and the city of Brescia. The page names no upstream source for them. A reader who skims the page could take "3 million visitors" as a Franciacorta figure. It describes a whole province that borders two major lakes.

Nearby series exist at other scopes. The 23 municipalities of the Visit Lake Iseo district passed one million presences in 2024 for the first time, with about 1,018,000, up 6.17%. Foreign visitors made almost 60% of them, led by Germany at about a quarter and the Netherlands at about 13%. We read those figures in Il Giorno, which attributed them to the Lombardy regional observatory. The city of Brescia recorded 986,406 overnight stays in 2024 from its tourist-tax data, up 3.9%. Neither is a Franciacorta figure.

The wine side shows a district working through excess supply. Gambero Rosso reported in June 2026 that the consortium had asked Lombardy to freeze new plantings until 2028. New DOCG vineyard claims were already suspended for 2026 by a ministry decree of 23 January. It put Franciacorta vineyards at 2,800 hectares in 2019 and 3,522 hectares in 2025, with potential output of about 27 million bottles against about 19.4 million sold. The magazine gave the growth in vineyard area as 24.4%. The two hectare figures it printed give 25.8%. The consortium's own infographic uses 3,634 hectares of planted vineyard. Neither source defines its measure, so both figures appear here with their sources.

What the UNESCO-effect studies claim

Two studies try to measure what inscription did. Neither is an official statistic, and both should be read with their limits stated.

For Langhe-Roero and Monferrato, the research firm formules, led by Guido Guerzoni, produced an impact study for the site's tenth anniversary in June 2024. Its executive summary is published on the site of the association that manages the property. It reports that arrivals in the Nizza Monferrato and Barbera component rose 237% and nights 325% between 2012 and 2023. It puts direct visitor spending at 88 million euros over ten years, and says each euro spent by visitors returned 2.37 euros to the local economy. The summary also counts short-term rental rooms and beds in each component. In the Langa of Barolo, beds in short lets rose from 425 in 2019 to 1,393 in 2023. In the Barbaresco hills they rose from 26 to 214.

Three limits apply. The tourism series begins in 2012, two years before inscription, so the growth rate includes pre-listing years. The summary says the designation "significantly influenced" 73% of the variables analyzed but does not show how that influence was separated from wider trends. And the summary labels its totals inconsistently: about 209 million euros in a chart, which includes the 88 million of visitor spending, and about 121 million in the text, which matches the chart's effects without that spending. Gambero Rosso repeated the 209 million figure. We treat neither as a settled total. The short-let counts are the closest thing to housing-pressure data that exists for any of the three landscapes. The summary gives no matching count for hotels.

For the Prosecco Hills, the Unitelma Sapienza figures summarised above are preliminary and available only through news reports. They describe growth in accommodation supply, which is different from growth in visitors. Gambero Rosso describes the comparison group but gives no method for choosing it and no period for its figures.

In the Langhe study, short-let beds rose sharply in every component between 2019 and 2023. The summary gives no comparable count for hotels, so the balance between the two cannot be measured.

Numbers that did not hold up

Several figures about these regions travel widely. Some describe a different area from the one named. Some are partial-year figures. Others could not be traced to any source.

The most common error is a scope error. A provincial or denomination figure gets attached to a wine landscape because it is the only number available. The second is time. A partial-year growth rate, such as the January-to-May figure for the Prosecco Hills, stays in circulation after the full-year data is out.

What nobody measures

Several basic figures are missing for all three landscapes. Each item below was checked against the regional statistics offices and consortium sources named in this article.

No official source publishes absolute arrivals or nights for the Prosecco Hills UNESCO area. Veneto releases growth rates only. No official source publishes any tourism series for the 19 municipalities of Franciacorta. For Langhe-Roero, the official absolute series cover the province and the tourist district, and neither matches the 29 UNESCO municipalities.

We found no official count of winery visits in any of the three. Italian tourism statistics count guests in accommodation. A day visitor who drives from Milan to a Franciacorta cellar, or from Venice to a Valdobbiadene tasting room, appears in no official tourism figure. We found no area-level measure of wine tourism revenue either.

No official crowding, rent or housing indicator exists at landscape level. The short-let counts in the Langhe study are the nearest proxy. Nothing equivalent was found for the Prosecco Hills or Franciacorta.

The national context is better covered. Italy's national arrivals and nights are tracked month by month in our Italy tourism record watch. The country's spending patterns by market are set out in who spends most in Italy per night. The two UNESCO landscapes are growing faster than their regions, and the exact size of all three is still unknown.

What this means for travelers, businesses and analysts

Travelers. The data says these are short-stay places. Visitors to the province of Cuneo and to the Langhe district average a little over two nights, and the Treviso average is similar. Short average stays suggest many visitors pair the hills with a nearby city or lake. Venice is the usual gateway for the Prosecco Hills, and our Venice travel guide covers it. Lake Iseo and Brescia sit next to Franciacorta. Nights grew 8.5% in the Prosecco UNESCO area and 11.9% in the Langhe tourist district in 2025, and short-let beds in the Langa of Barolo component more than tripled between 2019 and 2023. Book early for harvest season.

Tourism businesses and investors. The official numbers point to demand rising faster than Veneto as a whole in the Prosecco UNESCO area (nights +8.5% against +0.9%). For the Langhe, the nearest official series, the ATL district, grew nights 11.9% in 2025. None of the three publishes an area-level absolute count, so market sizing has to start from provincial or district totals and be labelled that way. Franciacorta's wine side has more vineyard than its sales need, with new plantings suspended for 2026 and sales flat. Any plan built on wine tourism there should not assume growth in wine volume.

Journalists and analysts. The figures that can be cited are these. Prosecco UNESCO area nights rose 8.5% and arrivals 7.3% in 2025, provisional (Regione del Veneto). Treviso province had 2,189,065 nights. Cuneo province had 2,326,624 nights and 993,982 arrivals. The ATL Langhe Monferrato Roero had 1,731,116 nights and 761,274 arrivals. Prosecco DOC bottled 667 million bottles, and Franciacorta sold an estimated 18,932,034 bottles. Inscription dates and decisions are 2019 (43 COM 8B.37) and 2014 (38 COM 8B.41). Do not cite the January-to-May 3.9% without its period, the "+30%" from the DOCG consortium, "3 million visitors" as a Franciacorta number, or district totals as UNESCO-site figures. Do not add provincial and district series together.
