Fermaid K is a versatile yeast nutrient blend containing both inorganic and organic sources of nitrogen, making it suitable for various winemaking styles. It provides a well-rounded nutrient profile to nourish yeast cells, ensuring a healthy and efficient fermentation. Fermaid K is widely used in winemaking to prevent sluggish or stuck fermentations.
 
The primary difference between Fermaid O and Fermaid K lies in their nutrient composition. While both products aim to support yeast during fermentation, Fermaid O is focused on organic sources of nutrients, aligning with organic winemaking practices. Fermaid K, on the other hand, offers a blend of both organic and inorganic nutrients, providing flexibility for winemakers who may have different fermentation needs.
