CellarScience®

Enhances fruit and chocolate-like aromas in red wines Helps stabilize color Our selected blend of SIY's, Ellagic Tannins, and a touch of Gum Arabic Added at the end of fermentation or the beginning of aging Red Wonder was developed to add fruit and chocolate flavor to red wine. It brings the body and richness of sur lie aging with the amazing impact of ellagic finishing tannins. The ellagic tannins in this blend were selected for their ability to impart chocolate flavors into the wine. Red Wonder is a blend of specially inactivated yeast (SIY), elected ellagic tannins, and a little bit of LiquiBody Gum Arabic. In addition to body and flavor this product helps reduce the need for SO2 and also helps to lock in color. You certainly could select an SIY, like our CellarScience Easy Sur Lie and then trial them with different ellagic tannins along with LiquiBody. But we've worked in small wineries and we know you are busy, so we've done that trialing for you and selected the blend that most often turned out really exceptional red wines. Directions: Use at the rate of 0.4 to 1.5 g per gallon of wine. Rehydrate in warm water or wine for 30 minutes and then stir directly into the tank or barrel. Once fully mixed it doesn't need any further stirring. We recommend starting with dosage of 1 g per gal (0.25 g per liter) and adjusting on further batches as needed.

Add to red wine fermentations on the skin  Releases aroma compounds, anthocyanins for color, and polysaccharides for mouthfeel Reduces necessary contact time / physical interaction normally needed for extraction Pectinase blend that breaks down cellulose and hemicellulose Enzo Red contains a selection of enzymes designed to promote deep, lasting color, structure, and aroma in fine red wines. Enzo Red is a blend of pectinases that will degrade both cellulase and hemicellulase, releasing anthocyanins and desirable skin tannins. It also releases aromatic compounds along with polysaccharides to help contribute to the aroma and body of your red wine. By breaking down pectins, Enzo Red helps with faster clarification and easier downstream filtering. Enzo Red can help to reduce the amount of punch downs or pump overs required. While there is no harm to keeping your existing schedule, it reduces the need for extended skin contact time, helps with extraction when an ideal punch-down schedule can't be maintained, and lessens the amount of time spent in pump over. For pump over in particular, this can be an advantage by lessening the shearing action on seeds that can occur when pumping must. Enzo Red is obtained from aspergillus niger and does not contain the enzymes cinnamyl esterase (production of barnyard flavors) or anthocyanase which is known to produce oxidized color hues in wine. Use: Dilute 0.04 to 0.15 g per gal (0.01 to 0.04 g per liter) into water and add directly into the crushed grapes or must. Perform bench trials to determine optimal usage or start with a dosage of 0.1 g per gal (0.025 g per liter) and adjust as desired on future batches.

NE HAZY is a low-flocculating, biotransformative yeast designed for NE-style hazy beers Enhances mouthfeel, turbidity, and hop aroma, creating a juicy, pillowy body and stable haze perfect for Hazy IPAs and juicy doubles Designed to be sprinkled directly onto the surface of your wort with no pre-oxygenation before pitching required Ferment between 62-75°F NE HAZY – The Yeast for Hazy, Juicy Beers NE HAZY is our specialized ale yeast for New England style (NE) hazy beers. If you’re looking to craft a juicy, flavor-packed brew with a lasting, stable haze, this strain has you covered. This low-flocculating, biotransformative strain enhances mouthfeel and turbidity through its interaction with glycoproteins and hop compounds, making it ideal for NEIPAs, Hazy IPAs, Pale Ales, and Juicy Doubles. During fermentation, it releases mannoproteins, a class of glycoproteins from its cell walls that create a soft, pillowy body while reinforcing haze stability.  NE HAZY actively participates in biotransformation, modifying hop-derived polyphenols and interacting with protein-rich compounds from wheat and oats. This process forms stable protein-polyphenol complexes that lock haze into suspension and intensify the beer’s juicy, full-bodied character. The result is an exceptionally stable haze, smooth-drinking beer with elevated mouthfeel, hop saturation, and tropical fruit expression. It ferments cleanly across a wide temperature range (62–75°F / 17–24°C) and is pressure-tolerant up to 12 PSI, making it highly versatile for a variety of brewhouse setups. Amplifies Hop Aroma & Flavor: Boosts tropical and citrus notes for NE-style juiciness Enhances Juicy Character: Transforms hop precursors into free thiols like grapefruit, passionfruit, guava, pineapple, peach, apricot, tangerine, and lime Boosts Haze Stability: Builds durable haze through glycoprotein and polyphenol interactions Flexible Fermentation: Performs across 62–75°F (17–24°C); pressure-tolerant to 12 PSI Robust & Reliable: Medium-low flocculation, consistent haze retention Attenuation: ~75–80% Alcohol Tolerance: 12% ABV Direct Pitch: No rehydration needed Quality Control: Every batch PCR-verified for purity and consistency High Cell Count: 15 g per sachet — over 36% more than standard 11 g dry yeast packs Dosage One sachet treats 5–6 gal (19–23 L). For larger batches, use 2–3 g/gal (0.5–0.8 g/L). Round up to the next full sachet rather than measuring precisely. Like all CellarScience yeasts, NE HAZY delivers professional-grade performance for both homebrewers and craft brewers producing the saturated, juicy haze that defines the modern New England IPA.

Seltzer-Specific Formula: Provides the precise Free Amino Nitrogen (FAN) and nutrients lacking in sugar bases for a clean fermentation. Rapid & Clean Fermentation: Achieve a finished seltzer in as few as 5 days with a neutral flavor profile. Prevents Off-Flavors: Designed to help yeast avoid producing common off-flavors (fusel alcohols, acetaldehyde, sulfur). Easy to Use: Dissolves quickly and completely without the need for stirring or heating. Nutrient blends designed for fermenting wine or beer simply don’t cut it when it comes to crafting seltzers. Both grape juice and wort naturally contain baseline levels of nutrients and free amino nitrogen (FAN) that are absent in seltzer bases. Simply increasing the dosage of nutrients intended for beer or wine fermentation isn’t effective. While this approach may meet the nutrient requirements, yeast need a certain level of FAN to ferment seltzers efficiently and cleanly. Unfortunately, most nutrient products on the market fall short of this mark. Some solutions promote nitrogen bound within dead yeast cells, like our own FermFed DAP Free, as being suitable for seltzers. However, after extensive trials, we’ve found that this approach doesn’t deliver the neutral flavor profile needed for the best seltzers. While fermentations may complete, they often do so with unwanted yeast-derived off-flavors. Yeasts that struggle to finish tend to produce fusel alcohols, acetaldehyde, and sulfur compounds. Our Dynamo 800 Nutrient is specifically formulated to provide yeast with everything they need to achieve a clean fermentation in as few as 5 days. When designing this nutrient, a decision was made to make flavor the top priority. Additionally, it dissolves easily without the need for stirring or heating, making it simple and efficient to use. Dynamo includes both organic and inorganic nitrogen to achieve a fast, clean fermentation in the challenging environment of seltzer production. Like the 800-meter race, it’s not just about pure speed—it’s about endurance and precision. While some products prioritize fermentation speed alone, we believe Dynamo 800 Nutrient strikes the perfect balance. It has been designed to go the distance and deliver the best flavor, especially when paired with CellarScience VELO. Rapid Start: Can finish fermenting in as few as 5 days. Specifically Formulated for Seltzer Fermentation: Designed to meet the unique nutrient needs of seltzer. Does Not Need Heat to Dissolve: Specifically designed without the need for stirring. Optimal Free Amino Nitrogen (FAN) levels: Provides essential nutrients absent in sugar-based fermentations, including both inorganic and organic nitrogen sources. Prevents Off-Flavors: Helps yeast avoid producing fusel alcohols, acetaldehyde, and sulfur compounds. Fast, Clean Fermentation: Supports efficient fermentation without compromising taste. Balanced Approach: Prioritizes both fermentation speed and final flavor. Proven Results: Extensively tested to outperform other yeast nutrients.   Sold in pre-measured pitch sizes for 2-Gallon, 5-Gallon, 1 BBL, 5 BBL batches as well as a 5-LB bulk pack.
