The 2020 Domaine Bonneau du Martray Corton Charlemagne is a Chardonnay from the prestigious region of Burgundy, France, specifically the Cote de Beaune sub-region in the Aloxe Corton appellation. This wine, produced by Domaine Bonneau du Martray, has received high praise from several notable wine reviewers.

Robert Parker's Wine Advocate awarded this wine an impressive score of 97, noting that it "unwinds in the glass with aromas of crisp Anjou pear, peach and nectarine mingled with white flowers, clear honey, nutmeg, mint and fresh bread." The review describes the wine as "medium to full-bodied, satiny and layered," highlighting its "terrific depth at the core and a long, saline finish." The Wine Advocate concludes that this "elegant, precise white Burgundy is built for the cellar," indicating its potential for aging.

Vinous also reviewed the 2020 Corton Charlemagne, giving it a score of 93. The review mentions that the wine has a "light bouquet at first, gaining intensity with time, scents of beeswax, chalk and touches of Mirabelle." The palate is described as "well balanced with a fine bead of acidity," and it is noted for being "quite tensile, backward and fine salinity." The review suggests that the wine will benefit from further aging, recommending a period of 3-5 years in the bottle for it to reach its full potential.

Jasper Morris from Inside Burgundy provided a range of 94-97 points for this wine, commenting on the analysis of its balance at 13.35% alcohol and pH 3.15. Morris describes the wine's nose as having "yellow fruit and a certain thickness of texture" with "ripe to baked apple notes." The palate, however, shows "wonderful potential with excellent grip due in part to a little youthful bitterness." Morris highlights the wine's "intensity and structure" and notes that it has the proper length, though he advises caution given its current stage of development.

Burghound rated the wine at 95 points, describing it as having an "airy, cool and layered nose" with "notes of green apple, white flowers and discreet hints of mineral reduction and wood." The review praises the wine's "almost painfully intense, sleek and tension-filled flavors," which display "beautiful cut and minerality." The finish is described as "chiseled, linear and austere," with Burghound concluding that this "old school CC" is both "rich and ripe yet it cuts-like-a-knife."

Overall, the 2020 Domaine Bonneau du Martray Corton Charlemagne is highly regarded for its aromatic complexity, balanced acidity, and potential for aging. It is a wine that promises to evolve and deepen with time, making it a noteworthy choice for collectors and enthusiasts alike.
