"Incredible aromas of apple skin, pie crust, praline and flowers. So young in the nose. Full-bodied with super-fine tannins. It’s tight and refined, yet structured and intense. Really long and beautiful. Still shy. Wonderful finish. 12 years on its lees before disgorging." (10/2021)

"Laurent-Perrier's imminently released NV Brut Grand Siècle #25 is showing beautifully, unwinding in the glass with an incipiently complex bouquet of pear, crisp stone fruit and mandarin mingled with hints of smoke, buttered toast and dried white flowers. Medium to full-bodied, layered and textural, with a fleshy core of fruit, terrific concentration and a racy spine of acidity, it's a deep, comparatively structured wine that will evolve beautifully in the cellar. As I've written before, this iteration is a blend of the 2008, 2007 and 2006 vintages, with 2008 lending #25 its depth and structure, 2007 contributing additional cut and 2006 additional richness. While the #25 exemplifies the seamless charm of this bottling, it's also one of the best propositions for long-term cellaring among recent renditions of Grand Siècle, and it will really reward time on cork.

"The newest release of Grand Siècle is based upon the superb and structured 2008 vintage (65% of the blend), along with the vivacious 2007 vintage (25%), and the creamy, luxurious 2006 (10%). The final blend is 60% Chardonnay from the Côte des Blancs and 40% Pinot Noir from the Montagne de Reims. The result at this stage exhibits its Chardonnay character, with toasty notes of ripe pear and spice on the nose and a creamy, silky texture and an edge of citrus. Although elegant and refined at present, the underlying power will doubtless come to the fore with time. (CC)" (1/2022)

Outer quote mark The NV Brut Grande Cuvée Grand Siècle No. 25 is bright and gracious in feel. Orchard fruit, mint, dried flowers, lemon peel, graphite and chamomile are beautifully lifted. The No. 25 is fresh and taut, but also has enough fruit to be approachable now. The blend of vintages - 2008 (60%), 2007 (20%), 2006 (20%) - is quite complementary. I liked the No. 25 more from magnum, but then again, Champagne often shows so well in larger formats. (AG) Inner quote mark (11/2021)

"Deep gold with the tiniest bead. Very pungently aromatic and with a texture as smooth as silk. Utterly luxurious. Slides over the palate with an undertow of surprisingly ripe Chardonnay. I'd drink this with a sophisticated fish dish, perhaps with a rich sauce. I love the gentlest of explosions on the palate. Surely this has a lower-than-average pressure? Very long. But it is not recommended for those who like their champagne on the austere side. This is to be launched in late 2021 but it tastes as though it was already gorgeous in 2020. 17/20 points (JR)_ " (10/2021)
