Fermaid K™ Yeast Red Wine

White Wine

Rosé Wine

To compensate must deficiency in nitrogen & micronutrients Add at the end of lag phase (12.5 g/hL) and after 1/3 sugar depletion (12.5 g/hL) Technical Datasheet The original and reliable Fermaid K™ is a blended complex yeast nutrient that supplies inorganic nitrogen (DAP), organic nitrogen (alpha amino nitrogen), key nutrients (magnesium sulfate, thiamine, folic acid, niacin, biotin and calcium pantothenate) and inactivated yeast. 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). With proper rehydration and handling, the yeast cell population should be at least 4 million cells/mL at inoculation. By the time the second Fermaid K™ addition is made, this population should have grown to about 100 million cells/mL. It is critical to remember that yeast are still reproducing during the stationary phase, and to do this effectively, especially in high sugar musts, they need oxygen as well as the components of Fermaid K™, including nitrogen (for protein synthesis), sterols and fatty acids (for maintaining alcohol resistance and permease activity). In addition, the inactivated yeast cell walls in Fermaid K™ adsorb medium-chain fatty acids that are toxic to yeast, and provide nucleation sites to help keep the yeast in suspension. Dosage recommendations: Add 12.5 g/hL (1 lb/1000 gal) Fermaid K™ at the end of the lag phase (beginning of alcoholic fermentation), and add 12.5 g/hL (1 lb/1000 gal) Fermaid K™ around 1/3 sugar depletion.
Fermaid O™ Yeast Red Wine

White Wine

Rosé Wine

To compensate must deficiency in nitrogen & micronutrients Beginning and 1/3 of the alcoholic fermentation Technical Datasheet Fermaid O™ is the latest nutrient developed by our winemaking nutrient research team headed by Dr. Anne Ortiz-Julien. Fermaid O™ is a blend of inactivated yeast fractions rich in organic nitrogen. Fermaid O™ does not contain added ammonia salts (DAP) or micronutrients. The importance of organic nitrogen from yeasts is well known as a highly efficient nutrient source for wine yeasts, especially when compared to inorganic nitrogen from DAP. In addition, Fermaid O™ consistently produces lower heat of fermentation and lower levels of negative sulfur compounds, compared with DAP. With its high content of organic nitrogen, Fermaid O™ can help winemakers achieve steady fermentations, while limiting temperature peaks. When inorganic nitrogen (DAP) additions are NOT desired, the use of Go-Ferm? or GO-FERM PROTECT? and Fermaid O™ is recommended. With this combination, Go-Ferm or GO-FERM PROTECT provides needed micronutrients during yeast rehydration, and Fermaid O™ (when added at 1/3 sugar depletion) supplies critical nutrients and survival factors to help the yeast avoid stressed conditions. Note: In low nutrient situations, yeast available nitrogen may be insufficient to avoid fermentation problems. Dosage recommendations: 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 around 1/3 sugar depletion.
Opti'Malo Plus Bacteria Red Wine

White Wine

Rosé Wine

Nutrients for Wine bacteria 1/3 de fermentation Technical Datasheet Opti’Malo PLUS™ was formulated to help support MLF in difficult wines. Add Opti’Malo PLUS™ directly to the wine before inoculating with the malolactic bacteria culture. Do not use Opti’Malo PLUS™ during bacteria rehydration. Opti’Malo PLUS™ is a unique blend of specific inactive yeasts rich in amino acids, mineral cofactors, vitamins and polysaccharides. These inactive yeasts are mixed with cellulose to provide more surface area to help keep bacteria in suspension, and to help absorb potential malolactic bacteria inhibitors. Dosage recommendation: Add 20 g/hL (1.6 lb/1000 gal) Opti’Malo PLUS™ to a small amount of water or wine and then add directly to the wine anytime from 48 hours prior to or up until the same time as the malolactic bacteria culture addition.
Stimula Cabernet Yeast Red Wine

Optimize the yeast metabolism and to promote the aromatic profile of Cabernet grape varieties At 1/3 through fermentation Technical Datasheet Stimula Cabernet™ is particularly rich in different nitrogen sources (especially small peptides), vitamins (biotin) and minerals (Magnesium, Zinc). Through our knowledge of the yeast metabolism and with recent results with our research partners, transporters of small peptides (dipeptides and tripeptides) have been identified. In the presence of sufficient oligo-elements, this peptide uptake results in increased yeast ester synthesis.
Stimula Chardonnay™ Yeast White Wine

To optimize the volatile ester biosynthesis by the yeast. Added at 1/3 of AF. Technical Datasheet Stimula Chardonnay™ is particularly rich in riboflavin, biotin, B6 vitamins and in Magnesium and Zinc. It will enhance the secondary aromatic metabolism and optimize the biosynthesis of aroma compounds and support the bioconversions of precursors to volatile esters until the end of fermentation.when added at 1/3 of fermentation
Stimula Pinot Noir™ Yeast Red Wine

mprove the expression of varietal aroma.• Enhance the synthesis and stability of fruity esters.• Reduce greenish and vegetal notes.• Avoid reductive characters. Added at the beginning of A Technical Datasheet Stimula™ is a new range of 100% yeast autolysate products developed to supply the optimal levels of organic nitrogen sources in order to optimize yeast metabolism and to promote the aromatic profile of different grape varieties.Stimula Pinot Noir™ is particularly rich in different nitrogen sources (free amino acids), specific vitamins and minerals to increase the aromatic profile while avoiding sulfur off-flavors.The addition of Stimula Pinot Noir™ at the beginning of the alcoholic fermentation (AF) will enhance yeast metabolism, increasing varietal precursors uptake, and aroma biosynthesis.
Stimula Sauvignon blanc™ Yeast White Wine

Supply the optimal levels of amino acids, sterols, vitamins and minerals known to optimize the aromatic yeast metabolism Add to the must at the begining of the alcoholic fermentation Technical Datasheet Stimula Sauvignon blanc is particularly rich in panthotenate, thiamin, folic acid and zinc and manganese in order to optimize the uptake of 4MMP and 3MH precursors and their bioconversion to volatile thiols.
Stimula Syrah Yeast Red Wine

Optimize yeast metabolism and to promote the aromatic profile of Syrah At the beginning of fermentation Technical Datasheet Stimula Syrah™ is particularly rich in different nitrogen sources (peptides and free amino acids), specific vitamins (pantothenate, thiamine) and minerals to increase the release of varietal aromas and avoid sulfur off-flavors. This specific composition results in an increase in the release of varietal aromas (thiols, terpenes and norisoprenoids). As the uptake of thiol precursors occurs in the very early stages of fermentation, the addition of Stimula Syrah™ at the very beginning of the alcoholic fermentation (AF) will enhance yeast metabolism, avoiding any catabolic repression and increasing the transporter’s efficiency. This is essential for thiol precursors and their bioconversion to volatile thiols, particularly 3-mercaptohexanol (3MH). In addition, the high level of vitamins (pantothenic acid) helps to avoid H2S production and limits the excessive reductive character that masks positive aromas. The optimized content in oligo-element (magnesium) also increases the yeast ethanol resistance.

Go-Ferm Protect™ Yeast Red Wine

White Wine

Rosé Wine

Use during active dry yeast rehydration Protectant during yeast rehydration Technical Datasheet GO-FERM PROTECT® optimizes the micronutrient bioavailability of Go-Ferm with the added benefit of survival factor protection through the NATSTEP® process. These survival factors include specific sterols and polyunsaturated fatty acids that strengthen the yeast membrane during rehydration, making it more resistant to fermentation stress. GO-FERM PROTECT® is used in the yeast rehydration water to create a suspension of micronutrients and survival factors that are bioavailable for selected yeasts. GO-FERM PROTECT® is recommended in place of Go-Ferm® for very difficult fermentation conditions, such as: 1. High maturity conditions (>25° Brix) to protect yeast against osmotic shock, helping avoid high VA production during fermentation. 2. High potential alcohol conditions to protect yeast against alcohol toxicity, helping avoid sluggish fermentation finishes. 3. Over clarified juices to help supply key yeast survival factors.4. Restarting stuck fermentations to protect and condition the “rescue yeast” against high alcohol conditions. Dosage recommendations: Use 30 g/hL (2.4 lb/1000 gal) of GO-FERM PROTECT® to stimulate and protect the rehydrating yeast. Note: This recommendation is based on a yeast inoculum of 25 g/hL (2 lb/1000 gal). If using more or less yeast, respect a ratio of 1 part yeast:1.25 parts GO-FERM PROTECT®. GO-FERM PROTECT® replaces Fortiferm and ENOFERM PROTECT that were previously offered in North America.
