Zilla Labs Ferm Boost | Pro-Grade Yeast Nutrient | 100g

Brew cleaner, faster, and more reliable beer at home with Zilla Labs Ferm Boost 100g.

Whether you’re tossing a Fresh Wort Kit into a FermZilla, pushing high-gravity Imperial Stout recipes, or battling nutrient-deficient worts, Ferm Boost ensures your yeast stays at peak cell health from start to finish. Made from 100% pure yeast autolysate, this professional-grade addition delivers natural organic nitrogen, free amino acids (FAN), B-complex vitamins, and bioavailable zinc. Unlike budget nutrients packed with chemical DAP salts, Ferm Boost feeds your yeast natural nutrients in the exact format it craves.

Say goodbye to stubborn stuck fermentations, sluggish attenuations, and rotten-egg sulfur smells. One 100g pouch provides enough high-performance nutrient to treat up to 660L of wort (over 30 standard 20L batches).

Key Features & Benefits

• 100% Yeast-Derived Autolysate: Pure, natural organic nitrogen and amino acids, no cheap inorganic DAP chemical salts. 
• High-Zinc Fortification: Packed with 1,800–3,500 mg/kg of bioavailable zinc to accelerate maltose uptake and drive rapid cell division. 
• Off-Flavor Defense: Eliminates yeast stress at the source, actively suppressing hydrogen sulfide (H₂S) and volatile sulfur off-flavors. 
• High-Gravity Ready: Powers through heavy grain bills, high-sugar adjuncts, and low-nutrient worts without stalling. 
• Re-Pitch & Propagation Support: Strengthens cell membrane integrity and glycogen stores, improving yeast harvest viability across multiple brews.

Dosage & Application

• Recommended Dosage: 0.15g – 0.30g per Liter (3g – 6g per standard 20L batch).
