Gault&Millau's review 2026

A little opening won't hurt, revealing notes of brioche, white fruit, white flowers and candied lemon. A nose that makes you salivate. The slightly vegetal palate reveals the dosage and, with it, roundness. The bubbles are dynamic, and the finish light with a touch of black pepper and white fruit. An accessible, well-made wine.

"Nothing is impossible to a valiant heart Jacques Cœur's maxim sums up the vision of the Maison Bonvalet. Pauline and Guillaume Bonvalet didn't inherit any vines, yet they made their dream come true, starting from nothing and building everything. The house was born in 2012 under Guillaume's impetus. The first bottles leave the cellar in 2014, after two years of aging. Determined to shake things up, demystifying Champagne, they reveal a little of its secrets, make it accessible and produce beautiful wines. Pauline and Guillaume Bonvalet work together to develop the range and image of their champagnes, combining the pursuit of the highest quality with the expression of terroir.
