Montée de Tonnerre is often regarded as the most complete of the Chablis Premier Crus, and Domaine Bernard Defaix has a long-standing reputation for producing serious, age-worthy wines from this site. Located just east of the Grands Crus, the vineyard shares a similar exposure and Kimmeridgian soils, giving wines of depth and line. The Defaix family has farmed organically here since 2009. Fermentation and maturation occur in a blend of stainless steel and older oak, imparting structure without overt wood influence. Each year, the wine exhibits a clear saline line, with notes of citrus, fennel, and oyster shell on the nose, followed by a mouthful of white stone fruit, a mineral cut, and a long, tapering finish. It opens up well with time in bottle and comfortably rewards cellaring. For those who prize Chablis with both detail and drive, this is a benchmark example of the style and the Montée de Tonnerre vineyard.

Domaine Bernard Defaix is a fourth-generation family estate with deep roots in the Chablis region. Their holdings in Montmains, one of the region's best-regarded Premier Cru sites, lie on Kimmeridgian clay-limestone soils and consistently produce wines of clarity and drive. The fruit is hand-harvested and fermented with native yeasts. A portion of the wine is aged in older oak barrels, while the rest is aged in stainless steel, striking a balance between structure and freshness. Each vintage shows the signature Montmains profile: citrus peel, oyster shell, and green apple on the nose, followed by a palate that's taut, stony and long. There's no excess weight here, just a clear line from vineyard to glass. Bernard Defaix's Chablis has become a dependable name for those who seek Premier Cru quality without the complications. A wine to enjoy now or cellar for several years, particularly in stronger vintages. Serve it cool, alongside shellfish or roast chicken.

Domaine Bernard Defaix has been family-run for four generations, with a long-held focus on expressing the unique identity of each Chablis cru. Bougros is one of the seven Chablis Grands Crus, lying on the western edge of the slope near the river, where the soils are shallow and rich in Kimmeridgian limestone. The domaine farms organically and harvests by hand. Fermentation takes place in stainless steel, with a proportion of older oak barrels used for ageing, lending texture without overt oak character. Each vintage of Bougros shows a firm mineral spine and a savoury, saline edge. The nose offers notes of preserved lemon, green apple, and oyster shell, while the palate brings tension and length, with citrus and chalky drive. Bernard’s sons, Sylvain and Didier, now lead the winemaking, continuing the estate’s work in vineyard-focused precision and restrained, site-led expression. This is a benchmark Grand Cru with a consistent record for age-worthiness and clarity.
