Lalbrew Farmhouse – 11g sachet

LalBrew Farmhouse™ Dry Yeast

LalBrew Farmhouse™ is the result of advanced research and development by Renaissance Brewing Science in collaboration with Lallemand. Using classical, non-GMO breeding techniques, the STA1 gene (responsible for diastatic activity) was removed, making this the first Saison strain that cannot metabolise dextrins. This allows brewers to achieve the “Saison” flavor profile—characterised by spicy phenols and tropical fruit esters—without the risk of over-attenuation or “gushing” bottles typically associated with traditional diastaticus strains. Additionally, it incorporates patented technology to prevent the production of hydrogen sulfide (H2S), resulting in a cleaner, more aromatic fermentation that enhances the yeast’s natural ester profile.

Key Benefits

• Non-Diastatic (STA1 Negative): Eliminates the risk of over-attenuation and cross-contamination of other beers.
• H2S Prevention: Patented technology ensures no sulfurous off-flavors, allowing fruit and spice aromas to shine.
• Authentic Phenolics: A POF+ strain that provides the essential peppery and clove-like complexity of traditional Saisons.
• High Heat Tolerance: Thrives at higher fermentation temperatures (up to 30°C) for increased ester expression.
• Robust Kinetics: Vigorous fermentation that typically completes within 5 days.

Applications

• Brewing: The premier safe alternative for Saisons, Bières de Garde, and Farmhouse-style ales. Also excellent for Belgian Pale Ales and experimental fruit-forward sours.
• Cider Making: A fantastic choice for ciders where a “Belgian” or “Farmhouse” character is desired without the long-term risk of thinning out the body due to diastatic activity.
• Distilling: Useful for creating a spicy, complex wash for specialty grain spirits, particularly when fermentation temperature control is limited.

Typical Usage

• Pitch Rate: 50 – 100g per hL of wort (to achieve 1 – 2 million viable cells/mL).
• Temperature Strategy: For more banana and clove notes, ferment at 20°C – 22°C. For increased pepper, bubblegum, and tropical fruit notes, ferment warmer at 25°C – 30°C.

Technical Data & Properties

• Classification: Saccharomyces cerevisiae (Hybrid).
• Attenuation: High (78% – 84%).
• Flocculation: Low.
• Alcohol Tolerance: 13% ABV.
• Optimal Temp Range: 20°C – 30°C.
• STA1 (Diastaticus): Negative (Undetectable).
• POF Status: POF Positive.

Storage and Handling

• Storage: Store in vacuum-sealed packaging in dry conditions below 4°C.
• Shelf Life: 3 years from the date of manufacture.
• Handling: Once opened, reseal and use within 3 days. If resealed under vacuum immediately, it can be stored until the expiry date.
• Pitching: Direct dry pitching is the preferred method; sprinkle evenly on the surface of the wort.

Summary

LalBrew Farmhouse™ is a technical breakthrough for the brewing industry. It offers the distinctive sensory characteristics of a Belgian Saison yeast with the safety and predictability of a standard ale strain, making it an essential tool for any modern brewery’s farmhouse program.
