Lallemand Yeast Nutrients

Smart brewers know that a yeast starter is the best way to ensure proper cell count and yeast viability prior to pitching. If you want a reliable starter for your batch of beer, you need to feed the yeast. Adding a yeast nutrient to the starter will give the yeast an added boost! Fermaid K is a yeast nutrient that works for starters and main fermentation. Here’s how it works:   Fermaid K is a complex formula that provides DAP, free amino acids, yeast hulls, unsaturated fatty acids, sterols; and micronutrients such as magnesium sulfate, thiamin, folic acid, biotin, calcium pantothenate, and other vitamins and minerals. Yeast use Nitrogen for protein synthesis and to maintain cellular growth. Nitrogen from the alpha amino acids contained in Fermaid K is utilized much more efficiently than from the ammonia salts like DAP. 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. 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. You do not need to add any additional fertilizers or DAP when adding Fermaid K. Use approximately 1 gram per gallon. Rehydrate in distilled water.   A rough approximate of weight is 1 tsp = 4.7 grams. We highly recommend using a scale to weigh the product for an accurate dose.   For a similar product check out CellarScience® FermFed Yeast Nutrient!

The Fermaid line of products are a range of nutrients that have been adopted from winemaking and put to use supporting beer fermentations as well.     Fermaid O is a newer formulation of the long trusted Fermaid K nutrient which replaces the inorganic DAP in Fermaid K with an organic source of nitrogen instead. The organic nitrogen in Fermaid O is better for your yeast, and that results in better beer!   Organic Nitrogen is easier for your yeast to digest, resulting in a smoother, more consistent fermentation. Fermaid O fermentations show fewer temperature spikes, which minimizes negative effects that can be caused by heat. Compared to DAP, Fermaid O results in more consistent and complete fermentation, and lower levels of negative sulfur compounds and other off-flavors.   Use at a rate of 1.5g / gal of wort. Dissolve in a small amount of wort or water and add to your fermenter at pitching.   Like Fermaid O? Then you will love CellarScience™ FermFed DAP Free Yeast Nutrient!

A new, advanced formulation of Go-Ferm Go-Ferm Protect is a natural yeast nutrient that is added to the yeast hydration water before adding your selected yeast strain. Its complex formula provides your yeast with the proper sterols, unsaturated fatty acids and micronutrients needed to begin fermentation in optimal shape. The great thing about Go-Ferm Protect is that the proper nutrients and vitamins are introduced BEFORE the yeast is added to the must. This way 100% of the nutrients are available to your selected yeast strain and won't be stolen away by any indigenous yeast or bacteria that may be present in the must before your yeast can become established. Go-Ferm Protect was created as a result of a multi-year study of problem fermentations by Lallemand and the National Agricultural Research Institute (INRA) in France. During this period, they looked at the adverse effects on the yeast from overripe fruit (>28 Brix), low nutrient levels, overclarification of the juice and poor fruit quality (Botrytis, rot, high bacteria count, insecticide and fungicide residue). Their research showed that musts deficient in sterols and unsaturated fatty acids made yeast more susceptible to ethanol toxicity (high alcohol), osmotic shock (high sugar), temperature and others stress factors. In response to this data they created the NATSTEP (NATural STErol Protection) process that incorporated sterols, unsaturated fatty acids, as well as vitamins and minerals into an advance yeast hydration nutrient: Go-Ferm Protect. Go-Ferm Protect provides a combination of protective and nutritional benefits that ensure your yeast begins your fermentation in peak form! The best part is that if your fruit is in great shape then Go-Ferm Protect will simply help your yeast out that much more! Go-Ferm Protect does not contain any DAP, as DAP is harmful to the yeast during the rehydration process. GO-Ferm is usually used in conjunction with our Fermaid K yeast nutrient; where Go-Ferm Protect is used at yeast hydration then Fermaid K is added at the first signs of fermentation and again after 1/3 sugar depletion. Use: Use at a rate of 1.25 g Go-Ferm Protect per 1 g of yeast. A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates. Click Here for a copy of MoreWine!'s Guide to Yeast Rehydration Like Go Ferm Protect?

The propagation and drying process of Servomyces has been specifically designed to accumulate a range of trace minerals and elements that are essential or limiting during alcoholic fermentation. Minerals, when incorporated into some sort of living tissue, are more efficacious than when presented as a salt. Servomyces presents better bio-availability of zinc, which is a very important factor in yeast nutrition. Servomyces can decrease fermentation time significantly and improve yeast sedimentation. It stimulates the uptake of maltose and maltotriose, depending on the brewing strain, which results in higher alcohol yields. Also stimulates protein synthesis and yeast growth, which leads to higher biomass production during propagation. Servomyces eliminates harsh sulphur notes and produces a smoother more balanced beer. 1 g Servomyces is used for 100 liters of wort for fermentation. 2 g Servomyces is used for 100 liters of wort for propagation.     *See the technical data sheet below for information on rehydration, usage and storage.
