Performs reliably in difficult fermentations, including low nitrogen musts and high alcohol potential Ideal for restarting sluggish or stuck fermentations Tolerates extreme conditions: low temperature, low pH, high alcohol, and high sugar Neutral sensory profile preserves varietal character and wine structure Strong fermentation kinetics with rapid yeast biomass development Enartis EZ Ferm 44 is a high-performance yeast strain developed for use in particularly challenging fermentation environments. It is especially effective in musts with low available nitrogen, high sugar content, and low temperature — conditions that often lead to sluggish or stuck fermentations. Its strong fermentative power, high alcohol tolerance (up to 17% v/v), and rapid biomass development make it an excellent choice for fermentation rescue operations and for fermenting difficult lots where reliability is critical. Rather than contributing intense aromatic esters, EZ Ferm 44 has a neutral profile that allows varietal and terroir characteristics to show through. It is also useful when the winemaking goal is to preserve structure and freshness without adding fruity overtones. Protocol for Use: Rehydrate in 10 times its weight of water at 35–38°C (95–100°F) for 20 minutes. After rehydration, slowly adapt the yeast to the must temperature by gradually adding must in small volumes over 10–15 minutes. Avoid temperature shocks greater than 10°C (18°F) between the yeast slurry and must. Inoculate immediately after acclimation is complete. For stuck fermentation restarts, follow a full restart protocol including detoxification and yeast acclimatization. Usage Rate: Recommended dosage is 20–30 g/hL — 0.2–0.3 g/L — 0.76–1.14 g/gal

Enhances Aromatics: Produces high levels of esters to significantly boost fruitiness in neutral grape varieties. Softens Mouthfeel: Absorbs polyphenols to reduce harsh tannins and naturally metabolizes malic acid for smoother, early-drinking wines. Versatile Application: Ideal for fresh reds, whites, rosés, and late harvest wines, performing well with high-acid grapes and alcohol levels up to 14%. RV171 was naturally isolated and chosen for its ability to produce large quantities of esters (like isoamyl esters), it can enhance the aromatic features of wines produced from neutral grape varieties. This particular yeast strain is capable of adsorbing polyphenolic compounds from its cell walls, thus lessening the tannic structure in young and fresh red wines. Grape juice inoculated with RV171 is likely to undergo malolactic fermentation since this yeast strain is able to metabolize malic acid during the primary fermentation stage. RV171 is the perfect option for making young, fresh, fruity and easily drinkable red, rosé and white wines, and also a fitting choice for late harvest wines. Fermentation Characteristics - It is particularly suited for high-acid grapes or varieties that will undergo acid adjustment. - Fermentation temperature range: 57-86°F (14-30°C) - Alcohol tolerance: up to 14%vol - Production of volatile acidity: low - Production of H₂S: moderate - high - No harmful sulfide - Competitive factor: sensitive - Glycerol production: ≥7 g/L Protocol for Use 1.

VL3 is a Bordeaux isolate that was selected following in-depth research identifying the molecules responsible for Sauvignon Blanc aroma. VL3 was found to enhance Sauvignon Blanc varietal characters and aromas (Mercaptopentanone, Mercaptohexanol, etc.) Subsequent experimentation has found this to be true of other white varietals such as Riesling, Pinot Gris, and Pinot Blanc as well. VL3 is well suited to aging on the lees and produces very low levels of VA and SO2. A premier yeast for Sauvignon Blanc fermentation worldwide. It is important to note that many of the sought after compounds that are enhanced by VL3 are actually sulfur based, so the use of oxygen and or Cu (copper) will effectively diminish or even remove them from the final wine if used in excess. Therefore, the use of nutrients is strongly recommended to avoid any H2S problems that would require oxygen or Cu to counteract. Best results from 60 to 68 degrees F, with an alcohol tolerance to 14%. Download the PDF Download the PDF

With the good characteristic of fermenting in low temperature, it also used in sparkling secondary fermentation. PM16 has rapid fermentation rate with short lag time. PM16 has neutral contribution to wine's organoleptic profile (low production of esters), makes it ideal for producing different types of red, white and fruit wines. Fermentation Characteristics - Fermentation temperature range: 50-86°F (10-30°C) - Alcohol tolerance: around 18%vol - Nitrogen requirement: low - Fermentation speed: fast - Production of volatile acidity: low - High tolerance of SO₂ - Production of SO₂: moderate - Production of H₂S: low - Production of foam: low - Production of glycerol: moderate - Flocculation: very good Application A wide range of applications for different types drinks, including wine, cider, mead and other fruits. Suitable for secondary fermentation for sparkling wine with short lag phase. Suitable for restarting fermentations, low temperature fermentations, and high clarified, low nitrogen and growth factors musts. A pure yeast selected for medium aromatic characters and robust fermentations. The fermentation kinetics of PM16 is complete and robust with clean varietal aromas without undesirable compounds. Good fermentation activity in the conditions of nutrient deficiency or high potential alcohol content. Low production of H₂S makes wine clean. Neutral sensory for wines to preserves the varietal properties. Protocol for Use 1. Rehydration Without Yeast Nutrition Dosage: 20 to 40 g/hL Rehydrate the yeast using water at 10 times its weight, with a temperature range of 95°F to 104°F (35°C to 40°C). Resuspend the yeast by gently stirring, and wait for 20 minutes. Blend the rehydrated yeast with a bit of juice/must, gradually acclimating the yeast suspension temperature to within 5-10 degrees of the juice/must temperature. Inoculate into the juice/must. 2. Rehydration with Nutri-Rehyd In the situations of tough fermentation conditions (high potential alcohol, over clarified must, low temperature), rehydrating yeast with Nutri-Rehyd is recommended. Carry out the rehydration procedure according to the selected Nutri-Rehyd product's instructions. Storage and Shelf Life Store in original sealed packages, in a cool and dry environment. Shelf life at the recommended conditions is 42 months. After opening the yeast must be used as soon as possible. Avoiding long-term storage at temperature above 86°F (30°C). Tips The difference between the yeast and must temperatures should not exceed 10 degrees during inoculation. Fermentations using active dry yeast can reduce the risk of contamination by wild yeast and harmful microorganisms. The rehydration process must not exceed 30 minutes.

Provides yeast-accessible nitrogen to support healthy growth and steady fermentation performance Supplies zinc and micronutrients that help improve yeast metabolism and stress tolerance Promotes cleaner fermentations by supporting robust yeast health in demanding conditions Helps improve consistency across batches, especially in nutrient-limited or high-gravity worts Useful for maintaining stronger yeast condition in serial/repitch scenarios Angel Yeast BrewNutri-AZ is a complete, balanced yeast nutrient designed to support healthy, consistent beer fermentations. It helps prevent sluggish performance by supplying organic nitrogen, yeast-accessible amino nitrogen, zinc, and micronutrients that promote strong yeast growth and stress tolerance—supporting reliable attenuation and a clean finish, especially in high-gravity, adjunct-heavy, or otherwise nutrient-deficient worts and other stressful fermentation conditions. Usage Rate 0.15–0.30 g/L (15–30 g/hL), adjusted based on wort composition and fermentation stress level Application Instructions Dissolve in sterilized water and mix thoroughly. Add 10–15 minutes before the end of the boil, or dose directly into cooled wort in the fermenter. Applications Beer • High-Gravity Beer • Adjunct-Heavy / Nutrient-Deficient Worts • Sluggish Fermentations • Stressful Fermentations
