Vin Doux Naturel (VDN): Muscat, Banyuls, Maury, Rivesaltes

Vin Doux Naturel is a naturally sweet, fortified wine (WSET) and a traditional term in French wine law. The INAO's Rivesaltes specification traces its legal codification to the Arago law of 2 August 1872, which recognised a distinct production of wines with 15% to 18% acquired alcohol, then to the Pams law of 13 April 1898, which reserved the traditional term 'vin doux naturel', and the Brousse law of 15 July 1914, which named the grape varieties. In the INAO's Rivesaltes, Banyuls grand cru and Muscat de Frontignan texts, the wines are made from low-yield vineyards where ripe fruit is partially fermented, then fortified with neutral grape spirit (at least 96% vol.) to halt yeast activity mid-fermentation. WSET states that Roussillon leads VDN production in France, representing 75% of the country's fortified style. The Rhône Valley makes VDN in Rasteau and Muscat de Beaumes-de-Venise, and the Hérault in Muscat de Frontignan.

• Mutage uses neutral grape spirit of at least 96% vol., between 5% minimum and 10% maximum of the must volume, measured as pure alcohol (INAO, Banyuls)
• Banyuls and Rivesaltes require at least 15% acquired alcohol and at least 45 g/L of fermentable sugars, and Inter Rhône gives at least 15% abv and a minimum of 45 g/L residual sugar for Rasteau; the INAO's 2010 Muscat de Rivesaltes text sets at least 100 g/L
• WSET names Rivesaltes, Maury and Muscat de Rivesaltes as Roussillon's VDN PDOs; Banyuls and Banyuls grand cru are VDN appellations on the Côte Vermeille coast
• Outside Roussillon: Rasteau (AOC 1944) and Muscat de Beaumes-de-Venise (AOC 1945) in the Rhône Valley, and Muscat de Frontignan in the Hérault (decree of 31 May 1936)

Mutage is the technique that makes a VDN: while the must is still fermenting, the winemaker adds neutral grape spirit of at least 96% vol., between 5% and 10% of the must volume measured as pure alcohol, which stops fermentation and leaves part of the grape sugar in the wine. WSET describes the effect: the high-strength spirit kills the yeast before it ferments all the sugar. The timing of mutage matters: the INAO's Rivesaltes specification says the colour of the wines varies with, among other factors, the stage of mutage, and that mutage with neutral alcohol during fermentation keeps the grape's primary aromas while enriching the wine with fermentation aromas. Red wines can be muted sur grains: the INAO's Rivesaltes specification calls mutage sur grains the technique generally used for Grenat, giving a purple colour and red and black fruit aromas, and in Banyuls the Rimage wines must be muted sur grains. The mutage operation must be carried out before 31 December of the harvest year, under the INAO specifications for Banyuls and Rivesaltes.

• Neutral grape spirit of at least 96% vol. is required in the INAO specifications for Banyuls, Rivesaltes and Muscat de Frontignan; for Rasteau, Inter Rhône states the alcohol must be neutral, grape-based and at least 96% proof
• In Banyuls, top-up mutage can be authorised or ordered by France's fraud-control directorate (DGCCRF) within a 10% pure-alcohol total, before the claim declaration (INAO)
• Banyuls Rimage wines must be muted sur grains; Banyuls Ambré, Blanc and Rosé come from must separated from the pulp before fermentation begins (INAO)
• Banyuls grand cru requires maceration of the destemmed harvest for at least five days, and the INAO links its mutage sur grains to maximum extraction of aroma precursors, anthocyanins and tannins

In Banyuls, Maury and Rivesaltes, the INAO specifications set styles apart by ageing environment. In Banyuls, Blanc and Rimage wines are aged in a reductive environment until at least 1 May of the year after harvest, including at least three months in bottle, while Ambré and Traditionnel wines are aged in an oxidative environment until at least 1 March of the third year after harvest (INAO). Maury uses Blanc and Grenat for its reductively aged wines and Ambré and Tuilé for its oxidatively aged ones, and Rivesaltes uses the mentions Ambré, Grenat, Rosé and Tuilé (INAO). By contrast with the reductive styles, Ambré and Tuilé wines are aged in an oxidative environment, in vat, foudres, or glass bonbonnes left outdoors at the mercy of the weather, and develop complex aromas that can reach rancio, which recalls roasting, dried fruit and especially walnut, according to the INAO's Rivesaltes specification. In Banyuls the Hors d'Age mention requires ageing until at least 1 September of the fifth year after harvest, and Rancio is reserved for wines that have acquired the 'goût de rancio' through their ageing conditions (INAO).

• Reductive: Banyuls Blanc and Rimage, Maury Blanc and Grenat, and Rivesaltes Grenat, which is made only from Grenache Noir (INAO)
• Oxidative: Banyuls Ambré and Traditionnel, Maury and Rivesaltes Ambré and Tuilé (INAO)
• Hors d'Age: in Rivesaltes, wines aged at least five years; in Rasteau, after more than 5 years of ageing (Inter Rhône)
• Rancio: the INAO's Rivesaltes text links the goût de rancio in part to the sotolon molecule, from ageing that ranges from century-old barrels to foudres, vats and glass bonbonnes

Banyuls and Banyuls grand cru share four communes of the Côte Vermeille, each of them a port: Banyuls-sur-Mer, Collioure, Cerbère and Port-Vendres (INAO). The INAO's Banyuls grand cru specification describes the most southerly vineyard in France, near the Spanish border, on steep slopes where the altitude falls from 917 metres at the Pic de Sailfort to sea level, on a bedrock mainly of Cambrian brown schist, with parcels cultivated in terraces up to 400 metres. It records annual sunshine above 2,600 hours, average annual rainfall under 650 millimetres, and wind on nearly 200 days a year, including the north-west Tramontane on 130 days. Rivesaltes, whose area spans communes of the Pyrénées-Orientales and the Aude, covered 5,000 hectares in 2009 with average production of 100,000 hectolitres, mostly as Ambré and Tuilé, from about 200 private cellars and 30 cooperatives that made 75% of the volume (INAO). The same text describes a Roussillon climate marked above all by the Tramontane, a north-west wind blowing one day in three. The INAO's 2010 Maury text places Maury's production area in the communes of Maury, Rasiguères, Saint-Paul-de-Fenouillet and Tautavel, and Muscat de Rivesaltes, reserved for white VDN, covers communes in both the Aude and the Pyrénées-Orientales.

• Banyuls: first recognised by decree on 6 August 1936; four Côte Vermeille communes (INAO)
• Banyuls grand cru: 174 hectares and average annual production of 4,000 hectolitres, made by two cooperative cellars and a few private cellars, per the INAO's 2011 specification
• Maury: first recognised by decree on 6 August 1936 (INAO); WSET reports Maury VDN production at about 3,000 hl against 40,000 hl in 1974, citing Bernard Rouby, head of the Maury VDN association
• Rivesaltes: 5,000 ha and 100,000 hl average production in 2009, mostly Ambré and Tuilé (INAO)

The INAO's Rivesaltes specification says Roussillon's wine was at first naturally sweet, made by techniques such as drying grapes on straw, twisting their stalks, adding honey to the must or heating, and was progressively made as vin doux naturel from the 13th century, a technique initiated by the physician Arnau de Vilanova (1238-1311), who invented mutage: adding alcohol to wine in fermentation to stop it. Neutral alcohol later replaced eau-de-vie in order to preserve the wine's aromas. The same text records AOC decrees for VDN on 6 August 1936, among them Rivesaltes, and a 1972 regrouping of three VDN appellations under the single name Rivesaltes. The INAO's Banyuls grand cru text places Banyuls, recognised in 1936, among the very first French AOCs, and records that Dr André Parcé, then mayor of Banyuls-sur-Mer and president of the Banyuls appellation's defence syndicate, sought a new appellation after the frosts of 1956 to preserve wines with a high share of Grenache Noir, which became Banyuls grand cru in 1962. WSET notes that VDN production has dramatically decreased in the last decades, and that as VDN sales declined, Maury obtained a PDO for dry reds, Maury Sec, in 2011.

• 1872: the Arago law recognised wines of 15% to 18% acquired alcohol; 1898: the Pams law reserved the term 'vin doux naturel'; 1914: the Brousse law listed the grape varieties (INAO, Rivesaltes)
• The Brousse law's varieties: Grenache Blanc, Grenache Gris, Grenache Noir, Macabeu, Muscat à petits grains, Muscat d'Alexandrie and Tourbat, known locally as Malvoisie du Roussillon (INAO)
• 1936: Rivesaltes, Banyuls and Maury were each first recognised by decree of 6 August 1936, and Muscat de Frontignan by decree of 31 May 1936; Muscat de Rivesaltes by decree of 29 August 1956 (INAO)
• Banyuls grand cru by decree of 16 November 1962; Rasteau VDN AOC in 1944; Muscat de Beaumes-de-Venise VDN AOC in 1945, applied from the 1943 vintage (INAO; Inter Rhône)
