Product details

FERMAID ® AT is a special complex yeast nutrient suitable for use in alcohol fermentation of grape must winemaking. Developed by Lallemand, the use of FERMAID ® AT reduces the occurrence of sluggish and stuck fermentations. FERMAID ® AT helps the maximum cell density get through the stationary phase and complete alcohol fermentation as quickly and as efficiently as possible especially under limiting available nitrogen conditions. FERMAID ® AT is a blended complex yeast nutrient that supplies a well-balance mix of inorganic (DAP) and organic nitrogen specific inactivated yeast, completed by thiamin. The thiamin allows a better assimilation of both nitrogen sources, and reduces the risk of off-flavors production. The inorganic mix is aimed at encouraging a more balanced metabolic fermentation outcome.
