Soirée Blanche history

An avenue becomes an open-air table

Épernay’s Soirée Blanche turns the Avenue de Champagne into a setting for a concert-picnic, Champagne bars and fireworks on France’s national day, 14 July. White clothing is the visual thread, joining residents and visitors along a street better known for merchant houses and cellar entrances. The municipal museum’s account describes tables and benches placed for participants and a picnic brought from home. That combination of public celebration and working wine street gives the evening its particular Épernay character.

The official sources used here establish several recorded editions, but they do not establish the event’s first year. The 2015 UNESCO inscription is a milestone celebrated by Épernay, not a founding date to attach to Soirée Blanche without evidence. Its story can be followed through the city’s 2023 programme, the avenue’s 2025 centenary celebrations and the official 2026 cancellation. Those dated records show the form and changing circumstances of the evening without inventing an origin.

The street that made the celebration possible

The World Heritage management body describes the avenue as a straight, 1.5-kilometre street leading into place de la République. Merchant families began settling there in the eighteenth century. Residences, reception buildings, production facilities and underground galleries formed a connected Champagne landscape, with the vineyards continuing beyond the town. The Soirée Blanche’s long outdoor table occupies that historic wine-trading setting; it is not a festival field detached from the place where the drink is made and stored.

The same heritage account describes roughly one hundred kilometres of chalk galleries arranged on several underground levels. Above them, the avenue combines grand façades, paved courtyards and gardens. It identifies Soirée Blanche on 14 July and December’s Habits de Lumière as recurring moments when this landscape becomes a festive gathering place. The street-level celebrations are one way the avenue’s heritage is experienced collectively, alongside individual cellar visits and ordinary walks past the houses.

A park-like avenue and a living calendar

The City of Épernay’s Habits de Lumière website dates redevelopment of the avenue from 2006, using the idea of an avenue-parc. Its account links that redesign with the setting for recurring public events, including Soirée Blanche. The same page records Site Remarquable du Goût recognition in 1994. These are milestones in the development and presentation of the venue; neither is presented as the creation date of the July evening.

The city’s avenue account names houses including Moët & Chandon, Perrier-Jouët, de Venoge, Boizel, Pol Roger, de Castellane, Mercier, Comtesse Lafond, A. Bergère, Collard-Picard, Michel Gonet, Esterlin, Leclerc Briant and Elodie D. They form the commercial and architectural surroundings of the party. Their own entrances, gardens and opening arrangements remain separate from the municipal street programme. That division between shared public space and individual house activity appears clearly in the surviving event leaflets.

2023: percussion, picnic and a popular dance

The city’s 2023 leaflet announced free public entertainment from 20:00 on Friday 14 July. Ritmistas dos Pily opened with strolling percussion on the avenue from 20:00 to 21:00. Ambre 9 then played near number 29 from 21:00 to 22:30, with a repertoire spanning French and international popular music, rock, pop, soul and disco. The programme placed people and musicians within the street instead of concentrating the entire evening inside one private house.

At 23:00, the 2023 programme scheduled fireworks by Eurodrop at place de Champagne. Ambre 9 was listed to resume near number 29 at 23:30. The leaflet distinguished free entertainment from paid cellar visits and Champagne bars. It also asked participants to dress in white. These details provide a compact portrait of that completed evening: a moving opening performance, a picnic concert, a fireworks gathering and a return to dancing, all anchored to named points on the avenue.

The houses added their own evening programmes

Épernay tourist office’s account of the 2025 national-day celebrations described de Venoge’s programme at 33 avenue de Champagne from 19:00 to midnight. Its garden offer included a DJ set, a food truck and Champagne by the glass or bottle. This was a house’s own invitation within the wider July setting. The producer-level programme created another place to spend the evening, with its own service and atmosphere alongside the municipal concert-picnic.

The same tourist-office page described chef Leonhard Bader of Die Ratsstuben in Ettlingen running an ephemeral restaurant at Domaine Michel Gonet, 37 avenue de Champagne, until 14 July. A reserved gastronomic tasting menu sat alongside smaller sharing plates available in the gardens or to take away. A live bluefin-tuna cutting and tasting was also advertised. These dated 2025 offers show the range of food activity surrounding the evening; they are not standing menus for a later summer.

2025: one street, two anniversaries

The year 2025 marked one hundred years of the Avenue de Champagne name. Épernay’s centenary programme included a Saint-Vincent procession on 18 January, the July Soirée Blanche and December’s Habits de Lumière. The city’s account specifically connected the 14 July picnic, popular dance and fireworks with the tenth anniversary of Champagne Hillsides, Houses and Cellars joining the World Heritage List. The summer evening therefore served as a public celebration of a major heritage anniversary as well as the national day.

Champagne Hillsides, Houses and Cellars was inscribed on 4 July 2015. The UNESCO property includes three groupings: the historic hillsides, Saint-Nicaise hill in Reims, and the Avenue de Champagne with Fort Chabrol in Épernay. The inscription recognises the landscape and buildings associated with Champagne production and trade. It does not award a separate designation to Soirée Blanche, but it explains why the avenue’s public celebration was linked so prominently to Champagne’s heritage in 2025.

What the anniversary celebrated

UNESCO’s account singles out Champagne’s role as a symbol of festivity, celebration and reconciliation under criterion (vi); criteria (iii) and (iv) address the expertise, organisation and production landscape. Those ideas give the 2025 anniversary evening a clear connection to its venue. The white-clad street gathering was a contemporary celebration in front of the houses recognised for production and trade, while the cellars beneath continued their working life. It was not a reconstruction of a nineteenth-century wine merchant’s party.

Part of Épernay’s broader July season

The municipal summer booklet for 2025 carried a Soirée Blanche poster advertising Monday 14 July from 20:00 on the Avenue de Champagne, with free access. Its three headline elements remained the concert-picnic, Champagne bars and fireworks. FCN appeared as grand patron, with Le Réveil de la Marne and PIJB Notaires Associés among the patrons. The inclusion of a dedicated poster in the city’s wider cultural programme places the evening within an organised municipal summer season.

That booklet also documented the tenth edition of Voi(x)là l’été!, running from 5 to 26 July 2025. The festival had been organised by the city since 2015 and used places including the Hôtel de Ville garden, Le Palace cinema and the Théâtre Gabrielle-Dorziat. Soirée Blanche and Voi(x)là l’été! are distinct names and programmes. Their appearance together in the July material helps a visitor understand Épernay’s summer calendar without transferring the founding date of one event to the other.

2026: heat changed the story

The city cancelled the public-domain activities of the Soirée Blanche planned for Tuesday 14 July 2026 because of forecast high temperatures and concern for participants’ health. Its notice specifically named the concert, picnic and fireworks. That scope matters: the municipal announcement recorded the cancellation of those public activities. It did not declare that every private producer’s restaurant, accommodation or independently booked cellar visit on the avenue had closed.

The Soirée Blanche visitor guide links to the city’s announcement and the tourist office’s programme pages. The 2023 and 2025 leaflets remain valuable records of how the celebration has worked, but their performers and timings belong to those editions. A future July visit needs a new municipal announcement and the chosen house’s own reservation. The avenue’s 1.5-kilometre setting remains there to explore even when the evening’s programme changes.
