What is Fermaid K used for?
Fermaid K is a blended yeast nutrient adapted to the fermentation of beer wort. Proper use of Fermaid K reduces the occurrence of sluggish and/or stuck fermentations.
When should I add Fermaid K?
It is best to add Fermaid K™ over two additions. The first addition is made at the end of the lag phase (6 to 12 hours after yeast inoculation) and the second addition is made around 1/3 sugar depletion (the end of exponential growth and the beginning of the stationary phase).
How do you use Fermaid O in Mead?
To avoid mead eruption accidents, degas must and dissolve yeast nutrient doses in 1 cup must prior to adding to the fermenter. At 24 and 48 hours after you pitch your yeast, add 4.25g Fermaid O to your must. At 72 hours after you pitch your yeast, add 4.75g Fermaid K and 3.7g DAP to your must.
How long is Fermaid K good for?
Add 40 g/hL (3 1/2 lb/1000 gal) of Fermaid O, 20 g/hL at the end of the lag phase and another 20 g/hL between 1/4 to 1/3 sugar depletion. Dated expiration. Store Fermaid O in a cool and dry area away from direct sunlight and strong odors. Under these conditions the shelf-life is 4 years in the original packaging.
Is Fermaid yeast nutrient?
Fermaid K is a blended complex yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen derived from inactivated yeast), sterols, unsaturated fatty acids, key nutrients (magnesium sulfate, thiamin, folic acid, niacin, biotin, calcium pantothenate) and inactive yeast.
What is the difference between Fermaid K and Fermaid O?
The main difference between the two Lallemand products, Fermaid O and Fermaid K is the source of nitrogen. In Fermaid O the nitrogen is organically derived in the form of autolyzed yeasts. In Fermaid K the source of nitrogen is DAP or diammonium phosphate which is a salt produced artificially.
What does Fermaid K do to wine?
The cell wall fractions, available through the included yeast hulls, absorb medium chain fatty acids that are toxic to the yeast. They also provide nucleation sites to help keep the yeast in suspension. Fermaid K is normally used in conjunction with GO-Ferm and added to the fermenting wine after 1/3 sugar depletion.
Do you need DAP with Fermaid O?
Fermaid O provides an organic source of nitrogen in the form of autolyzed yeast hulls. What is this? Rather than using diammonium phosphate (DAP) as a source of nitrogen the nitrogen is from an organic source. It is also recommended to add Fermaid O in staggered doses, as detailed above.
How do you use Fermaid?
To Use: Fermaid O should be mixed with room temperature water before adding to an active fermentation to avoid CO2 release and overflowing of tanks or barrels. The amount of water used is not critical. Simply add enough to make a slurry.
Is Fermaid K necessary?
The unsaturated fatty acids and sterols available in Fermaid K are important survival factors needed to maintain alcohol resistance. They also help keep volatile acidity levels low. Fermaid K is normally used in conjunction with GO-Ferm and added to the fermenting wine after 1/3 sugar depletion.
What is Fermaid A?
Fermaid® A is a complex yeast nutrient blend of inactivated yeast (organic YAN; alphaaminonitrogen) and diammonium phosphate (inorganic YAN). An addition elevates the yeast’s intracellularamino nitrogen reserve reducing the chances of a stuck or sluggish fermentation.
Is Fermaid Ka yeast energizer?
Fermaid is a blended complex yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen derived from inactivated yeast), sterols, unsaturated fatty acids, key nutrients and inactive yeast.
