Best Water Treatment Salts for Homebrewing (2026)
Updated How we research
Water is most of your beer, and adjusting its mineral content with brewing salts can sharpen or soften a beer to match its style. Common additions include gypsum (calcium sulfate) to accentuate hop bitterness, calcium chloride to round out malt fullness, and Epsom salt or others for finer tweaks. Buy food-grade salts of good purity, and store them sealed and dry since some absorb moisture and clump. The goal is not maximum minerals but a balance that suits the beer, so small, measured additions matter. Water salts appeal to brewers who have the fundamentals down and want to refine flavor and mouthfeel, and to anyone working with very soft or very hard local water. Start by knowing your base water, whether from a report or distilled as a blank slate, then adjust toward a profile for the style. A simple sulfate-to-chloride balance nudges a beer hoppy or malty. These are inexpensive and last a long time, so a small starter set of a few salts covers most brewing needs.
