Alpha-amino nitrogen is a key parameter for assessing the level of assimilable amino acids in must. Its determination helps predict alcoholic fermentation performance, optimise nutrient additions and reduce the risk of sluggish fermentations, stuck fermentations and aroma defects.
Fast, reliable results allow wineries and laboratories to manage yeast nutrition more precisely, preventing fermentation issues before they affect wine quality.
