What You Need to Know
The glaze forms a thin film where reducing sugars react with amino acids in a Maillard reaction, producing melanoidins that give the glossy brown color. Simultaneously, the wine’s acidity lowers the surface pH, accelerating protein denaturation and further caramelization of sugars. Antioxidant spices such as pepper and cumin help moderate oxidation and enhance flavor.
