Additives & Spices

Fine-tuning your brew goes beyond grains, hops, and yeast—additives and spices help refine flavors, adjust water chemistry, improve clarity, and enhance fermentation. Whether you're crafting beer, mead, cider, or wine, the right additions can balance acidity, optimize yeast health, clarify your final product, and introduce bold, unique flavors.

Our Additives & Spices collection includes essential brewing ingredients that enhance quality and consistency. This category features acids, salts, and water treatment products to adjust pH, minerals, and water profiles for perfect mash efficiency and fermentation. Anti-microbial agents like potassium metabisulfite and potassium sorbate help prevent unwanted microbes and stabilize your beer, wine, or mead. Clarifiers and finings such as Irish moss, gelatin, and Biofine improve clarity and reduce haze, while enzymes boost starch conversion, improve attenuation, and optimize fermentation.

For those looking to add complexity and depth, we offer a wide range of spices, including citrus peels, juniper berries, heather tips, and more. Yeast nutrients and enhancers like DAP, Fermaid K, Go-Ferm, and Phantasm thiol precursors support fermentation health and improve overall yeast performance.

From adjusting water chemistry to boosting yeast performance and experimenting with spices, these brewing additions allow you to take full control of your process and craft truly unique beverages.
