Classy Cactus Extra Premium Brewing Yeast Nutrient

Classy Cactus Extra Premium Brewing Yeast Nutrient

Classy Cactus is a comprehensive yeast nutrient formulated to address the nutritional deficiencies often found in modern brewing environments, such as high-gravity brewing or the use of large proportions of adjuncts (like maize, rice, or sugar). It contains readily available nitrogen sources alongside a proprietary blend of amino acids, vitamins, and minerals including Zinc, Magnesium, and Calcium. These components are vital for yeast health and metabolic efficiency at every generation. By ensuring a nutrient-balanced environment, Yeastlife Extra™ reduces yeast stress, promotes faster diacetyl reduction, and minimises the production of unwanted sulphur compounds. This results in more predictable fermentation timelines and a cleaner, more consistent final product.

Key Benefits

• Faster Fermentation: Reduces lag phase and accelerates attenuation.
• Consistency: Provides a predictable fermentation curve, batch after batch.
• Reduces Off-Flavours: Minimises hydrogen sulphide (H2S) and other sulphur-related off-flavours.
• Supports Yeast Health: Vital for breweries that harvest and re-pitch yeast, ensuring vigour is maintained over multiple generations.
• Optimises High-Gravity Brewing: Alleviates the stress caused by high osmotic pressure and nutrient-poor adjunct worts.

Applications

• Brewing: The primary application. Essential for all-malt worts with high gravity, as well as worts containing adjuncts. It is particularly effective for lagers where clean profiles and fast diacetyl reduction are critical.
• Winemaking: While Lallemand Oenology typically recommends Fermaid®, Yeastlife Extra™ can be used in specialty fruit wines or honey-based fermentations (meads) that are naturally deficient in nitrogen and minerals.
• Distilling: Highly effective for grain-based or sugar-based washes (like those for vodka or rum) to ensure complete attenuation and maximum ethanol yield in high-stress, high-sugar environments.
• Cider Making: Useful for juice-based fermentations that may lack the complex amino acid and mineral profile found in malt, helping to prevent “rhino farts” (sulphur off-flavours).

Typical Usage

• Standard Dosage: 4 – 10 g/hL of wort.
• Propagation Dosage: 8 – 15 g/hL for yeast starters or propagation phases.
• Application Method: Add to the kettle 10 minutes before the end of the boil or directly to the whirlpool. It can also be added in-line to the wort main during transfer to the fermenter.

Technical Data & Properties

• Appearance: Light brown/cream powder.
• Composition: Specialised blend of Inorganic Nitrogen (DAP), Organic Nitrogen (Amino Acids), Minerals (Zn, Mg, Ca), and Vitamins.
• Solubility: High solubility in water/wort.
• pH: Neutral.
• Regulatory: Meets EU General Food Law (Regulation (EC) No 178/2002) and is suitable for use as a processing aid in most regions.

Storage and Handling

• Storage: Store in a cool, dry, well-ventilated area. Keep containers tightly closed when not in use.
• Handling: Avoid creating dust during handling. Ensure the product is kept away from moisture to prevent clumping.
• Shelf Life: 3 years from the date of manufacture when stored in original unopened packaging.

Summary

Classy Cactus is the ultimate “fermentation insurance” for professional brewers. It bridges the nutritional gap in challenging worts, ensuring that yeast remains healthy, vigorous, and clean-tasting, regardless of gravity or adjunct levels. It is a cost-effective solution for improving brewery throughput and product quality.
