Zinc Ferm | Yeast Nutrient | 30mL | Zilla Labs

Maintain Yeast Vitality and Prevent Stuck Fermentations

Zilla Labs Zinc Ferm is a high-potency liquid yeast nutrient engineered to maintain peak yeast health, vigour, and overall vitality throughout fermentation. By delivering concentrated, bioavailable zinc (an essential trace element often deficient in wort), Zinc Ferm helps ensure your brew attenuates completely, preventing slow or stuck fermentations and protecting your beer's final flavour profile.

Key Benefits for Brewers

• Promotes Healthy Fermentation: Supports optimal cell multiplication and metabolic performance for strong, active fermentations.

• Prevents Stuck & Sluggish Batches: Drives fermentations to complete attenuation, even in high-gravity or high-adjunct worts.

• Prevents Off-Flavours: Reduces yeast stress to eliminate unwanted sulphur compounds, diacetyl, and ester imbalance.

• Essential Enzyme Catalyst: Directly supplies the zinc required to activate critical metabolic enzymes during alcohol production.

The Role of Zinc in Fermentation Performance

Zinc functions as a vital cofactor for key yeast enzymes, including alcohol dehydrogenase, which is essential for sugar conversion and healthy cell membrane synthesis. Standard all-malt and high-adjunct worts often lack sufficient bioavailable zinc, causing yeast stress and extended lag times. Zinc Ferm solves this deficiency, giving yeast the exact mineral boost needed for fast starts and clean finishes.

Dosage & Application Directions

• Dosage Rate: Add 0.5 ml per 23 L batch (scale proportionally for larger commercial vessels).

• Timing: Pitch directly into the fermenter at yeast pitch.

• Integration: Mix thoroughly into the cooled wort alongside your chosen yeast strain.

Storage & Handling

• Temperature: Refrigerate between 4°C – 6°C.

• Environment: Store in a cool, dry place away from direct sunlight to preserve full nutrient integrity.
