On the opposite flank of the Valvan valley to Vaillons, and with a deep soil of bleu d'argile (blue clay) and plenty of limestone rocks, Montmains is commonly held to produce 'textbook' Chablis of minerality and verve. This is from 0.65-hectares of very old vines--70 years on average--in the lieux-dits of Vaux Miolot and Les Bouts de Butteaux. At this stage, it's the most aromatically complex and alluring of the Premier Crus. The notes below capture the wine well.
"Since the passing of her husband, Stéphane, three years ago she has continued the tradition of making rich, leesy, complex wines with subtle oak, layers of wax and cream and fresh, focused acidity. Commendable stuff." 93 points, Tim Atkin MW, Decanter
"The 2018 Chablis Montmains 1er Cru is lifted, weightless and airy, and yet there is plenty of power that emerges from thee glass. Citrus and floral notes come together in this elegant style of wine. A whole range of floral and citrus notes add character. The 2018 is understated today, but also appears to be holding back much of its potential." 89-92 points, Antonio Galloni, Vinous
