Chablis

Chablis lies near Auxerre in the Yonne département, mid-way between Beaune and Paris, and its vineyards cover the hillsides along the Serein, a little river aptly named (serein means serene). The Chablisien is a small, well-defined region of slopes bordering the valley of the Serein, a tributary of the Yonne, set among the plateaux of the Auxerrois in the Paris Basin, and the AOC Chablis geographical area spans 17 communes of the Yonne. The wines of Chablis form a pyramid of four levels. Petit Chablis AOC at the lowest tier (created 5 January 1944) covers vineyards on the higher portions of the slopes or the edge of the plateau, on brown soils derived from hard limestones with patches of sandy silts, mostly between 230 and 280 metres. Chablis AOC at the next tier accounted for 66% of average marketable volume over the five years 2015-2019 and had 3,715.99 hectares in production in 2022. Chablis Premier Cru includes 40 named climats that can be grouped under 17 names, on both banks of the Serein: the historic climats, attested since the Middle Ages, are classified on the right bank and more recently revealed climats on the left bank. For wines grown on Premier Cru plots, the words Premier Cru and/or the name of the climat of origin may be added to the name Chablis on the label. Crossing to the left bank, Vosgros is the first climat, and a clockwise tour of the vineyards continues through Montmains, Vaillons, Vau de Vey, Côte de Léchet and Beauroy. Chablis Grand Cru AOC operates as a single appellation divided between 7 climats, which form a continuous band along the upper part of the valley from Bougros in the North-West, through Preuses, Vaudésir, Grenouilles, Valmur and Les Clos to Blanchot in the South-East. The Grand Cru vineyards lie to the North-East of the town, facing the sun at altitudes of 100 to 250 metres along the right bank of the Serein.

• Chablis Premier Cru: 40 climats that can be grouped under 17 names; historic climats on the right bank, more recently revealed climats on the left bank
• Chablis Grand Cru: 7 climats in a continuous band from Bougros (North-West) through Preuses, Vaudésir, Grenouilles, Valmur and Les Clos to Blanchot (South-East), at 100-250 m

Chablis Grand Cru vines grow on marls and Kimmeridgian limestones containing tiny fossilised oysters called exogyra virgula, rocks formed during the Upper Jurassic some 150 million years ago, and the appellation is one of the few French AOCs to define itself in terms of its geology. The underlying structure is the Côte des Bars cuesta, which exposes Upper Jurassic sediments: a cornice of hard limestone, the Calcaire du Barrois, above a long slope of compact marls, the Marnes à exogyra virgula, named for the small comma-shaped oysters they contain. The delimited parcels occupy the flanks of the Serein valley and its side valleys on these marl slopes, locally reaching the Calcaire du Barrois or the Calcaire à Astartes where slopes allow, and the soils are always calcareous. By the 1970s the market had recovered to the extent that the appellation had to be redefined, some growers (Durup, Laroche) argued for the outlying Portlandian limestone while others, led by William Fèvre, defended the Kimmeridgian clay, and the authorities chose the expansionist route. Both the delimited parcel area for AOC Chablis and the separate area for the premier cru mention date from an INAO national committee session of 31 January 1978. In the appellation's single document, published in the EU Official Journal, the climate is oceanic, slightly modified by continental influences, with only 650 millimetres of annual rainfall at Auxerre and a mean annual temperature of 10.8°C, and the wines owe their lively, mineral character to the zone's cool oceanic climate. The BIVB places Chablis in a more semi-continental, wetter zone that is often susceptible to springtime frosts. The northern location gives Chablis a cooler climate than most other Burgundy regions, and the wines tend to show higher acidity than Chardonnay produced in warmer climes. The climate carries a fairly high risk of winter and spring frosts: growers devised spraying and heating of parcels to fight frost, and late spring frosts wiped out the entire Chablis crop in 1945, 1951, 1953 and 1957. Chablis is commonly produced as an unoaked Chardonnay, although methods vary widely and some producers favour oak barrel maturation. AOP Chablis is a dry white still wine, and the BIVB's tasting note gives Chablis a rather light colour, pale gold or greeny-gold, with a very fresh, lively and mineral nose of flint, green apple and lemon.

• Substrate: marls and Kimmeridgian limestones with fossilised exogyra virgula oysters, Upper Jurassic, some 150 million years ago
• Structure: Calcaire du Barrois cornice above slopes of Marnes à exogyra virgula, with the Calcaire à Astartes lower down; soils always calcareous
• 1970s boundary debate: Durup and Laroche argued for Portlandian limestone, William Fèvre defended Kimmeridgian clay, and the authorities chose expansion; the delimited parcel area dates from 31 January 1978
• Climate: oceanic, slightly modified by continental influences (EU single document), more semi-continental and wetter (BIVB); 650 mm annual rainfall at Auxerre, 10.8°C annual mean (EU single document); fairly high risk of winter and spring frosts

Vine growing in the Chablisien is attested from the early Middle Ages: a monastery was founded at Chablis in 510 and ceded in 867 to the monks of Saint-Martin de Tours, and in 1114 the Cistercians founded Pontigny Abbey near Chablis and later installed a cellar in the town, the Petit Pontigny, whose buildings still stand. Les Clos may be the original kernel of the Chablis vineyards, first exploited by the Cistercians of Pontigny. After phylloxera, downy mildew and powdery mildew, reconstitution of the vineyard only truly restarted in the second half of the 20th century, and by 1949 Chablis had dwindled to under 500 hectares. Producers formed their first syndicate in 1908 to fight usurpation of the name, and in 1923 a cooperative cellar, La Chablisienne, was created at Chablis; it still brings together 25% of producers, and the BIVB key figures list a cooperative cellar at a quarter of production. The Fédération de défense de l'appellation Chablis is the recognised defence and management body for Petit Chablis, Chablis and Chablis Grand Cru. Among named estates, Domaine Long-Depaquit, presented on the Albert Bichot website, is a 52.1-hectare estate farmed organically and holds the monopole La Moutonne, a 2.35-hectare parcel lying 95% in Vaudésir and 5% in Preuses and formerly owned by the monks of Pontigny Abbey; la Moutonne is a usage name used for centuries for a vineyard of Chablis Grand Cru. At Maison Joseph Drouhin, Robert Drouhin acquired nearly 40 hectares in Chablis in the late 1960s, together with the 18th-century Moulin de Vaudon; the house's Chablis wines carry the Drouhin Vaudon name, and its Grand Cru holdings are in Bougros, Preuses, Vaudésir and Les Clos. Domaine William Fèvre's own web address now redirects to the Domaines Barons de Rothschild (Lafite) site, which lists it among the group's estates; William Fèvre began building his holding in the 1950s and 1960s, and it eventually grew to 47 hectares. Domaine Raveneau makes a bottling from Forêts, a climat within Montmains.
