WEST COAST is a refined evolution of the classic American ale strain engineered for modern brewing while honoring its proven roots Clean, versatile, and reliable, it’s ideal for brewers seeking subtle depth without compromising balance at an unbeatable value Designed to be sprinkled directly onto the surface of your wort with no pre-oxygenation before pitching required Ferment between 59-72°F WEST COAST is a refined evolution of the classic American ale strain engineered for modern brewing while honoring its proven roots. It delivers the same clean, dependable performance as CALI, with just a trace of fruit character that lends a quiet depth to the final beer. When fermented under pressure up to 12 PSI, WEST COAST can be pushed warmer to help reduce turnaround time while producing an even cleaner profile with its subtle fruit character pushed further into the background. This nuance stays well in the background, complementing rather than competing with hops or malt. Ideal as a house strain, WEST COAST can refresh a Flagship recipe or anchor a new one, offering robust, reliable fermentations every time. Designed for simplicity, it can be pitched directly into wort no oxygenation or rehydration required. Flocculation: Medium to High Fermentation: Range: 59-72ºF (15-22°C) Pressure-Ready: Performs great under pressure up to 12 PSI Attenuation: Approximately 75–84% Alcohol Tolerance: 10% ABV Direct Pitch: No rehydration needed Reliable & Consistent: Every batch undergoes PCR testing for quality High Cell Count: 15g per sachet—over 36% more than standard 11g dry yeast packs Dosage: One sachet is enough to treat a 5–6 gallon batch. When calculating for larger batches, use at a rate of 2–3 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly. Like all CellarScience yeast, WEST COAST offers professional-grade performance for both homebrewers and craft brewers at an unbeatable value. If you love the clean versatility of CALI but want a touch more character, West Coast  is your next go-to strain.

Our top choice for Seltzers — highly efficient at metabolizing simple sugars with minimal off-flavors (low fusel/sulfur) Amazing house strain – for neutral-profile ales VELO delivers – rapid fermentation while maintaining a clean, neutral profile Doesn’t require temperature control - Loves to ferment Hot Ferment between 60-94°F Designed to be sprinkled directly onto the surface of your wort with no pre-oxygenation before pitching required Amazing as a House Strain VELO is a high-performance ale yeast selected for speed, flavor neutrality, and wide temperature tolerance. In internal sensory comparisons, VELO’s ester suppression and clean finish exceeded CellarScience CALI, while offering faster kinetics and a wide operating range that, within reason, can substantially reduce the need for temperature control. We’ve found it to be a dependable house strain across styles, especially for hop-forward ales. delivering clean results quickly while staying remarkably forgiving across real-world fermentation conditions Why It Works in Seltzers For hard seltzer production, VELO excels thanks to highly efficient metabolism of simple sugars (“mono- and disaccharides”) with low fusel and sulfur byproducts when supported by a complete nutrient regimen. When developing our Seltzer nutrient Dynamo 800 we tried many yeasts and Velo was consistently the best.  From there we tweaked the formulation specifically for Velo with over 60 fermentations.  Across broader sensory feedback beyond internal  bench work, VELO consistently presented as noticeably cleaner than several common industry benchmarks, delivering a true neutral, blank-canvas base that stays out of the way of your seltzer flavor additions. Lagers Fermented at Warmer Temperatures (Sometimes called pseudo-lagers) VELO excels in this role by delivering a clean, lager-like profile at ale fermentation temperatures. Its wide operating range (60–94°F / 16–34°C), fast kinetics, and low ester/phenol expression let you run lager-style recipes in the mid-60s to low-70s °F without temperature control. When you ferment under pressure (up to 12 PSI), you can push these lager-like beers toward the upper end of VELO’s range right up to 94°F while still maintaining a neutral, crisp finish. High attenuation and medium–high flocculation help the beer finish dry and drop clear quickly, making VELO an amazing house strain for clean, lager-like beers on an ale timeline. Technical Attributes Neutral & Clean: Ester/phenol expression held very low; as clean or cleaner than CellarScience CALI in sensory comparisons. Fast Fermentation: Wraps primary quickly, reducing tank residency and tightening production schedules. Wide Temp Range: Performs cleanly from 60–94 °F (16–34 °C) with minimal off-flavors—useful where tight temperature control isn’t feasible. Pressure-Ready: Stable up to 12 PSI, ideal for closed or spunded ferments. Hop-Smart: Preserves hop brightness in modern IPAs while remaining tidy in low-IBU and malt-forward beers. High Attenuation: ~75–83 % for a dry, polished finish; alcohol tolerance up to 10 % ABV with full nutrient support. Medium–High Flocculation: Drops bright post-fermentation while staying in suspension long enough to finish cleanly. Thermotolerant Physiology: Robust stress response (e.g., trehalose storage) supports clean performance at elevated temperatures. Specifications: Fermentation Temperature: 60–94°F (16–34°C) Apparent Attenuation: ~75–83 % Alcohol Tolerance: up to 10 % ABV (with complete nutrient regimen) Flocculation: Medium–High Pressure Tolerance: up to 12 PSI Format: 15 g high-cell-count sachet (≈ 36 % more than standard 11 g) Direct Pitch: No rehydration required Quality Control: Every batch PCR-verified for purity and consistency Applications Clean ales and pseudo-lagers • West Coast/Cali-style IPAs • Pale & session ales • Kölsch-like ferments • Hard seltzers and other sugar-based ferments Dosage Homebrew: One 15 g sachet treats 5–6 gal (19–23 L). Scale-up: Use 2–3 g/gal (0.5–0.8 g/L). When scaling, round up to the next full sachet for consistency. VELO is the practical house strain for clean results on a tight timeline—neutral like CALI, ferments fast, handles a wide temperature range, and produces a polished finish in beer and seltzer when paired with appropriate nutrients.

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.

ACID yeast will complete both Lactic and Alcoholic fermentation on its own, producing an acidic beer with light notes of fruity floral esters Shave days off your sour beer making process by skipping the kettle souring step altogether! No need for added equipment to purge your kettle with CO2 or add heating to maintain high temps for lactic fermentation To reduce acidity, pitch an ale yeast strain to stop souring and wrap up alcoholic fermentation Ferment between 66-77°F CellarScience offers high-quality yeast that is easy to use, consistent, and available at a tremendous value Consistent, repeatable results without the need for kettle souring. ACID from CellarScience is a naturally selected, GMO-free yeast strain that has the ability to ferment and sour beer simultaneously. In a traditional kettle souring process, you'll need to pre-boil wort, purge it with CO2, pitch lactic acid, wrap and seal the kettle, and insulate or provide a heat source to maintain lactic acid fermentation temps that may be as high as 100°F+ depending on your chosen pitch. ACID allows brewers to bypass those steps and produce sour beers with the equipment they already own. Pitch directly in your fermenter and ACID yeast will complete both Lactic and Alcoholic fermentation on its own. When allowed to run its course, this yeast produces a rounded, refreshingly acidic beer with light notes of fruity floral esters. If you wish to reduce acidity, simply pitch a regular ale yeast strain when the desired pH is obtained which will hault souring and complete the rest of the alcoholic fermentation. Every batch is PCR tested to ensure quality. Dosage: Use at a rate of 80-120 grams per barrel, depending on wort temperature and gravity. Direct Pitch or Rehydrate: ACID yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation.
