Fontaine-Gagnard produces white Burgundy from the region's most prestigious terroirs. The winery's portfolio centers on three Grand Cru Chardonnays from the Montrachet slope: Criots-Bâtard-Montrachet, Le Montrachet, and Bâtard-Montrachet. These limestone-rich vineyard sites in Bourgogne yield wines of mineral precision and age-worthiness. The winery's Chardonnays have been assessed by Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. Criots-Bâtard-Montrachet and Le Montrachet both average 93 points across prestige evaluations, while Bâtard-Montrachet averages 92.4. The specificity of these Grand Cru designations—each with distinct soil composition and microclimate—shapes the character of Fontaine-Gagnard's whites.
