Discover the unsung hero of brewing: Zinc. This essential nutrient plays a critical role in yeast health and fermentation performance. While many brewers focus on their mash tun, they often overlook the importance of zinc, which is lost during the boil. Without enough zinc, your yeast may struggle, leading to slow fermentation, unpleasant flavours, and lower quality beer. Fortunately, The new BSY-N01 | Zinc Booster provides a solution. Designed to be applied on the cold side, this innovative product guarantees that your yeast has the necessary nutrients for optimal performance, right in the fermenter.

Bluestone Yeast's Approach: At Bluestone Yeast, we understand the value of preserving brewers' established methods, rather than starting from scratch. Our sterile zinc and vitamin liquid solutions are designed to seamlessly integrate into traditional brewing processes. Our nutrient boost is easy to incorporate into any size brewery, so you can continue brewing as usual while our solution works behind the scenes to guarantee each fermentation reaches its maximum potential. It's a simple yet powerful improvement, enhancing your process without interrupting your flow.

Cold-side zinc and vitamin supplementation is designed to complement your current practices, not replace them. It’s a simple tweak that fits seamlessly into any brewery’s workflow:

No Recipe Alterations: You won’t need to change your grain bill, hop schedule, or water profile. The nutrient addition happens after the boil and has zero impact on your beer’s recipe or flavour profile – except for making it more consistent.
Seamless Integration: Adding a sterile nutrient solution is as easy as adding yeast. Dose it in as you transfer wort to the fermenter. It takes seconds, with no special equipment needed.
Works With What You’re Already Doing: Keep oxygenating your wort, pitching healthy yeast, and managing fermentation as usual. Our Zinc Booster and Vitamin Booster additions simply ensure those steps are even more effective by giving yeast the complete nutrition they need.
All Benefit, No Drawback: Because Bluestone’s nutrient solutions are sterile and flavour-neutral, they won’t introduce contamination or off-notes. You’ll only notice that fermentations are more vigorous and reliable – an improvement on an already good process.

The Boil Takes Its Toll

We all know that boiling vegetables for a long time depletes the nutrients and destroys the vitamins.
The same happens with boiling wort. We try to mitigate this by adding nutrients hot side which has a limited impact. But there are an array of essential vitamins, minerals and amino acids that simply do not survive the boiling!

The solution Cold side nutrient boost

Scientifically formulated and laboratory tested. Our sterile Nutrient Booster range are designed for ease of use.
Whether you are looking at replacing lost Zinc or replacing the essential vitamins and amino acids lost during wort boiling we have you covered.
Cold-side zinc supplementation ensures the yeast receives an immediate boost of bioavailable zinc and vitamins, exactly when it needs it most.

The role of Zinc in Brewing?

Zinc is critical for yeast metabolism, cell growth, and stress resistance.
- Zinc boosts yeast metabolism for faster, more efficient fermentations
- Expect fermentation to finish 1-2 days sooner.
- Free up tanks faster and increase production capacity.
Zinc supports strong, healthy yeast—leading to clean, crisp fermentations.
Reduces off-flavours and stuck fermentations.
Improves attenuation and final product stability.
Zinc supports essential enzymes, including alcohol dehydrogenase, which drives yeast’s metabolic processes, enabling efficient sugar conversion.
Zinc enhances the yeast’s ability to withstand higher alcohol concentrations, making it indispensable for high-gravity brews.

Pairing Zinc and Vitamin Booster

Yeast requires a balance of vitamins and minerals to perform optimally.
Combining zinc supplementation with a comprehensive yeast nutrient blend ensures yeast receives all the building blocks needed for fast, clean, and reliable fermentations.
Combine our Zinc and vitamin booster to ensures the yeast receives an immediate boost of bioavailable nutrients exactly when it needs it most.

Lagers

The clean, crisp profile of lagers relies on healthy yeast. Zinc supplementation ensures strong yeast performance for these low-temperature fermentations.

High-Gravity Beers

From imperial stouts to Triple IPAs, high-gravity beers stress yeast.
Zinc boosts their resilience and prevents incomplete attenuation.

Yeast Propagation

For brewers reusing yeast, zinc ensures the harvested yeast remains healthy and viable for successive brews.

Pro Tips for Using Nutrient Booster

Calculate Your Dosage Size:

Our 250ml, 500ml or 1L bottle of zinc cover all fermenter sizes. For high-gravity beers, double the amount add for a standard ale.

Timing is Key:

Add our zinc booster in-line as the fermenter is being filled for even distribution.

Pair with Yeast Nutrients:

Combine with a complete yeast nutrient blend for maximum performance.

Pricing works out to be less than 1 cent per L of beer produced.
