FERMAID AT - YEAST NUTRIENT 100gm

Fermaid At - Yeast Nutrient 100gm

• Lallemand 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-balanced 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-flavor production.
• The inorganic mix is aimed at encouraging a more balanced metabolic fermentation outcome.

Application:

• Beginning and 1/3 of the alcoholic fermentation

Nutrients For:

• Yeast

What For:

• To compensate for must deficiency in nitrogen

Usage:

• Wine Making
• Mead Making
• Rum
• White Spirits washes
• Hard Seltzer

Dosage:

• 35-40 g/hL

Application:

• Lallemand Fermaid® AT is a blended complex yeast nutrient developed for low to moderate YAN conditions, which supplies a well-balanced mix of organic nitrogen (wine yeast-derived), inorganic nitrogen (DAP), and the vitamin thiamine.
• The nitrogen content of Fermaid® AT is composed of 50% yeast-derived organic nitrogen (amino acids and peptides) and inorganic (NH4+).
• Organic nitrogen is assimilated more gradually than inorganic nitrogen. Different amino acids are taken up at different rates.
• Once inside the cell, the alpha-amino acids are integrated directly into proteins, degraded into ammonium (NH4 +), or used to produce fruit-driven esters.
• The NH4 + component is involved in the biomass production of yeast cells. Reaching critical biomass is essential for successful fermentation.
• The addition of thiamine to this complex nutrient allows for an improvement in the assimilation of both nitrogen sources and reduces the risk of off-flavour production.
• Fermaid® AT contains the maximum permissible level of thiamine as stipulated by the OIV / EU.
• This preparation is designed to assist wine yeast in the latter half of alcoholic fermentation (AF).
• When Fermaid® AT is used in place of a DAP-only nutrient strategy, significant improvements in the sensory profiles of the wines are also evident.
• Fruit-driven esters and a reduction in sulphidic characters can be achieved.

Usage Guidance:

• Re-suspend Lallemand Fermaid® AT in 10x its weight in water.
• Ensure it is well dispersed with no lumps, then add immediately to the tank.
• Dose Rate of Fermaid® AT: Fermaid® AT is recommended for low YAN conditions.
• A 30g/hL (300 ppm) dose of Fermaid® AT provides 36 mg/L of actual YAN.
• For moderate to high YANs Lallemand recommends using the product Fermaid® O.
• Circumstances such as fruit quality, variety, winemaking practice, must parameters, yeast nutrient demand, and cellar conditions are infinitely variable and impact on yeast performance.

Storage:

• Store in a cool (below 25⁰C) and dry environment away from direct sunlight and strong odours.
• Shelf life at the recommended storage conditions is 4 years from the date of production.
