Natural Brewer's Peptides made from brewing-native ingredients. Stops the bacteria that ruin batches. One sachet, same workflow as your existing yeast.
The two bacterial spoilers behind roughly half of all beer contamination events. They produce off-flavors, haze, ropiness, and acidity that ruin entire batches.
Low ethanol, higher pH, and residual sugars make non-alcoholic and low-alcohol beers a microbiological minefield.
Pasteurization is capex-heavy and ruins hop aroma. Sterile filtration removes desirable yeast character. Phages are expensive and need cold chain.
Natural Brewer's Peptides are a blend of fermentation-derived peptides, barley protein matrix, and hop co-actives. Same kinds of ingredients you already trust in beer, concentrated for protection.
Each component is food-grade and approved for brewing use.
Saccharomyces (your brewing yeast) is unaffected. The peptides target bacterial cell walls only. Fermentation kinetics, attenuation, and flavor profile match your underlying strain.
Commercial brewing yeasts pre-blended with our Natural Brewer's Peptides. One sachet, drop-in replacement for your usual lager or ale yeast. Same fermentation behavior, with built-in protection against the bacteria that cost you batches.
Classic clean lager strain blended with our peptide formulation. For pilsners, helles, dortmunder, and traditional lagers.
Neutral American ale strain blended with our peptide formulation. For pale ales, IPAs, stouts, porters, and most US craft styles.
Natural Brewer's Peptides on their own, no yeast. Add to wort at pitch alongside your preferred strain. The right choice for NOLO production where yeast bundling doesn't fit.
Higher-load formulation tuned for low-ethanol and higher-pH conditions. For dealcoholized and arrested-fermentation NOLO production.
Broader-spectrum formulation for brewers loyal to specific yeasts and controlled-sour programs.
Standard Natural Brewer's Peptides formulation. For brewers using their own preferred yeast strain who want standalone protection.

Not a yeast company. Not a phage company. We do one thing: keep spoilage bacteria out of your beer.
