• 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.
