92 Points, Antonio Galloni, Vinous:

"The NV Extra-Brut Les Grands Blancs is a rich, vinous Champagne that shows the more extroverted side of Mesnil. Low dosage brings that out even more. Lemon confit, marzipan dried flowers, spice and chamomile add striking inner sweetness to a wine that balances power with translucent energy. The Grands Blancs is a terrific introduction to these wines. The current release is a blend of vintages 2015 and 2014. Dosage is 3 grams per liter. Disgorged: May, 2019." 11/20

92 Points, James Suckling,

JamesSuckling.com: "Bright and more fruit-driven than the vintage wines, this has bright lemon and white-grapefruit aromas, as well as salted almonds. It's fresh, creamy and well balanced with a fine mousse. 100% chardonnay from Le Mesnil sur Oger and Oger. From organically grown grapes. Disgorged May 2023. Drink now." 07/24

91 Points, William Kelley, Robert Parker's Wine Advocate:

 "Disgorged in May 2019 with three grams per liter dosage, Moncuit's NV Extra-Brut Grand Cru Les Grands Blancs is the latest rendition of the cuvée that formerly simply bore the name Blanc de Blancs. Derived from the 2015 and 2014 vintages, it's showing beautifully, wafting from the glass with aromas of ripe lemons, honeycomb and hints of the warm bread to come with a little more age on cork. On the palate, the wine is medium to full-bodied, fleshy but nicely defined, with an open core that reflects its constituent vintages, a delicate mousse and a sapid, penetrating finish." 04/20
