LalBrew Diamond™ Lager Dry Yeast
LalBrew Diamond™ Lager yeast originates from the prestigious Group II (Frohberg) lineage in Germany, offering brewers a reliable and high-performing tool for traditional lager production. This strain is celebrated for its neutral flavor and aroma profile, allowing the delicate nuances of malt and noble hops to shine without ester interference. It exhibits vigorous fermentation even at cold temperatures, with high attenuation and superior flocculation that simplifies the clarification process. While designed for traditional cold fermentation (10°C–15°C), it is also the centerpiece of Lallemand’s “Fast Lager” method, allowing for reduced tank residency times without compromising the crisp, clean finish essential to world-class lagers.
Key Benefits
- Authentic German Origin: Sourced from the Doemens Academy Culture Collection for true-to-style lager performance.
- Clean & Neutral: Minimal ester and sulfur production ensures a crisp, professional sensory profile.
- High Flocculation: Settles rapidly to produce brilliant, clear beer with minimal filtration.
- Robust Performance: High alcohol tolerance (13% ABV) makes it suitable for heavy styles like Doppelbocks.
- Efficiency: Capable of vigorous fermentation, reaching terminal gravity in 5–7 days under optimal conditions.
Applications
- Brewing: The primary choice for the full spectrum of lager styles, including Munich Helles, German Pilsner, Bohemian Pilsner, Dortmunder Export, Vienna Lager, Oktoberfest/Märzen, Schwarzbier, and Bocks. Also excellent for California Common (Anchor Steam style) when fermented at the higher end of its range.
- Distilling: Useful for creating clean, grain-neutral washes for vodka or light whiskey where a low-congener fermentation is required.
- Cider Making: An excellent option for cold-fermented, “crisp” ciders where a slow, clean fermentation is desired to preserve delicate apple aromatics.
Typical Usage
- Pitch Rate: 100 – 200g per hL of wort (achieving 5 – 10 million viable cells/mL). High-gravity brews or very cold starts may require the higher end of this range.
- Fast Lager Method: Can be pitched at 17°C for 24 hours before dropping to 12°C to accelerate production time.
Technical Data & Properties
- Classification: Saccharomyces pastorianus (Bottom-fermenting).
- Attenuation: High (77% – 83%).
- Flocculation: High.
- Alcohol Tolerance: 13% ABV.
- Optimal Temp Range: 10°C – 15°C
- STA1 (Diastaticus): Negative.
- POF Status: POF Negative (no phenolic off-flavors).
Storage and Handling
- Storage: Must be stored in a vacuum-sealed package in dry conditions below 4°C.
- Handling: The strain is highly sensitive to oxygen once opened. Use within 3 days of opening.
- Pitching: Direct pitching is recommended—sprinkle evenly on the wort surface. Ensure the temperature difference between the yeast and wort is less than 10°C to avoid “petite mutants” and sluggish fermentation.
Summary
LalBrew Diamond™ Lager is an indispensable “workhorse” lager strain. It provides the technical reliability of dry yeast with the authentic sensory results of a traditional German liquid culture, making it the perfect choice for breweries prioritizing clarity, speed, and stylistic accuracy.
