Laurent-Perrier’s Grand Siècle Iteration No. 27 is the house’s prestige, multi-vintage Champagne, built to approximate a “perfect year” by blending three strong harvests rather than relying on one. For No. 27, multiple critics confirm the blend of 2015, 2013, and 2012, with 2015 as the core (reported at 65%), and a 60/40 split of Chardonnay to Pinot Noir. Robert Parker’s Wine Advocate notes the intent behind that mix: an “emphasis on Chardonnay to counterbalance the concentration of Pinot Noir.” The wine was disgorged in January 2025, and the dosage is consistently reported at 7 g/L; James Suckling also cites “nine years on the lees.”

The best reviews are outstanding. James Suckling awards 99 points, calling it “impressively aromatic” with “honeysuckle, violets and lavender,” plus “bread dough” and a “hint of light caramel,” finishing with a palate that is “full-bodied but not at all heavy, turning almost weightless.” That combination of scale and lift is echoed elsewhere. Jeb Dunnuck (98) describes a “bright silver-yellow hue” and a nose of “wet stone, delicate smokiness, apricot, and lavender,” followed by “silky complexity and pillowy mousse” with “key lime, lemon meringue, green apples, and a salty spice.” He recommends 2027–2057 and adds that it is “less obvious than No. 26,” with “delicate almond and tertiary nuances hiding underneath.”

Antonio Galloni at Vinous (96) emphasizes complexity and savory detail—“pear, dried flowers, chamomile, mint, sage and ginger”—and finds it “dynamic in the glass,” noting that a “touch of vintage 2015 savoriness…add[s] character rather than overpowering the wine.” Wine Advocate (95+) similarly highlights “pear, peach, lemon confit and freshly baked bread,” “tangy acidity,” and a “long, resonant finish,” concluding it is “yet another distinguished Grand Siècle in the making.”
