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.

Sourvisiae® is a modern fermentation solution that produces sour beers through one simple fermentation step
Clean and neutral flavor, ideal for traditional and modern sour beer styles and an excellent base for fruited sours
Sourvisiae® is a bioengineered (GMO) strain of Saccharomyces cerevisiae
Lallemand premium brewing yeast offers brewers unmatched consistency, reliability and purity from one batch of beer to the next
Sourvisiae® is a bioengineered ale yeast strain (Saccharomyces cerevisiae) capable of producing lactic acid during fermentation to provide brewers with an easy, reproducible, and mono-culture product for sour-style beer production.
Sourvisiae® contains a single genetic modification, a lactate dehydrogenase gene from a food microorganism, which enables the yeast to produce high levels of lactic acid, the main compound that gives sour beers their flavor. Sourvisiae® allows the brewer to ferment and sour the beer in one simple step, reducing cross-contamination risks, lowering costs, cutting total process time, and allowing brewers to obtain a consistent product. The brewing process is conducted without any modifications; Sourvisiae® is pitched just like conventional yeast and ferments in a normal fermentation time. Sourvisiae® does not produce other flavor compounds associated with Brettanomyces, Lachancea, or Lactic Acid Bacteria, providing a cleaner and more reproducible souring process, with much shorter fermentation times.
Microbiological Properties
Classified as a bioengineered Saccharomyces cerevisiae, a top-fermenting yeast. Finished product is released to the market only after passing a rigorous series of tests. *According to the ASBC and EBC methods of analysis.
Typical Analysis of Sourvisiae® Yeast:
Percent solids 93% – 96%
Living Yeast Cells ≥ 5 x 10 9 per gram of dry yeast
Wild Yeast < 1 per 10 6 yeast cells
Bacteria < 1 per 10 6 yeast cells
Brewing Properties
In Lallemand’s standard conditions, wort at 20°C (68°F), Sourvisiae® yeast exhibits:
Vigorous fermentation that can be completed in 5 days
Medium to High Attenuation and Medium to High Flocculation
Highly acidic and slightly fruity flavor and aroma
The optimal temperature range for Sourvisiae® yeast when producing traditional styles is 15°C (59°F) to 22°C (72°F).
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
Attenuation may appear lower due to the formation of lactic acid. Production of lactic acid does not result in a loss of CO2. When sugar is consumed to produce lactic acid, there is no change in density. Therefore, the amount of residual sugar in the finished beer is lower than the final density would imply.
This yeast produces a very acidic beer, with final beer pHs in the range of 3.0 and lactic acid in the range of 8 – 15g/L. Vigorous fermentation can be completed within 5 days.
The resulting flavor and aroma profile of the beer is a slightly fruity acidic beer. Because of the resulting low pH and highly acidic conditions, we do not recommend re-pitching this yeast.
Flavor and Aroma
Tangy, sour, slightly fruity

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.

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. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels.
