Product details

FERMAID O™ is an organic nitrogen source that helps to nourish yeast, improve aromas, and allows for good control over fermentation. Reliably lowers peak fermentation temperatures and improves fermentation kinetics (especially at the end of fermentation), resulting in fewer sulfur off odours like H2S. Due to FERMAID O™’s highly consistent and balanced amino acid profile, the nitrogen lasts longer and less nutrient is needed than when using inorganic nitrogen sources (DAP). FERMAID O™ use has been correlated with positive aromatic expression (thiols and esters) and enhanced mouthfeel. FERMAID O™ is a unique yeast autolysate with a high content of free assimilable amino acids and peptides. It contains 100% organic nitrogen and natural source of essential micronutrients vitamins (thiamine, biotin, pantothenic acid) and minerals (magnesium, manganese, zinc).
