Maillard reaction in Champagne occurs after disgorgement and produces which flavors?

• A. A chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. This is a molecular change that happens POST-DISGORGEMENT. A series of chemical reactions; a type of non-enzymatic browning. Amino acids (proteins) interact with sugar to create flavor compounds. Wines that were disgorged 10 years ago will have Maillard reaction, for example. Late-disgorgement wines will not. Brut nature WILL NOT undergo this type of flavor development. Signature flavors: pate a choux, toasted puff pastry.
• B. A fermentation temperature change
• C. A color change due to sunlight
• D. A barrel aging reaction

Answer: (A)

Maillard reaction is a non-enzymatic browning that happens when amino acids react with reducing sugars, producing a cascade of flavor compounds and browned, toasty notes. In Champagne, this chemistry develops during aging after disgorgement as the wine sits with time (and a small amount of sugar from the dosage) under aging conditions. The result is flavors reminiscent of baked goods and pastry—pâte à choux and toasted pastry notes. The other options describe processes that don’t create those baked, toasty flavors: a fermentation temperature change affects yeast activity, sunlight exposure causes photochemical color change, and barrel aging brings oak-derived flavors rather than Maillard-derived biscuit/toast notes.
