Tasting Profile
Nose: Pear, ripe apple and citrus with brioche, toasted almond, hazelnut, dried flowers and honey.
Palate: Richer and more developed than Jacquart’s standard Brut, showing ripe orchard fruit, pastry and nutty complexity. Five years of lees aging contributes a creamy mousse and biscuity depth, while Chardonnay maintains freshness and precision.
Finish: Crisp and persistent, with lingering apple, brioche, almond and a subtle saline-mineral character.
Sommelier’s Take
This is an excellent choice for someone wanting more maturity and complexity than a straightforward NV Brut without moving into prestige-cuvée pricing. The five-year aging adds noticeable brioche and nutty richness while retaining enough citrus-driven acidity to keep it lively.
Winemaker Notes: Jacuart's Mosaique Signature is aged for 5 years before disgorgement. The result is a fresh and rich wine with notes of pear, apple, brioche, hazelnut and dried flowers. An excellent match with John Dory or other white fish.
Wine Enthusiast (91 points) "All three main Champagne grapes go into this wine, resulting in a rounded character and sense of aging and maturity. It has a brioche flavor alongside the white fruits and the crisp acidity. The wine is finely balanced, ripe while also crisp at the end. Drink now."
