Palmer's Brewing Water Adj App is a free Android application developed by Palmer Brewing Solutions Inc. It is designed to assist brewers in calculating salt and acid additions to create different brewing waters suitable for specific beer styles. The app provides suggested mineral profiles for common beer styles, which consist of ranges for calcium, magnesium, total alkalinity as calcium carbonate, sulfate, chloride, sodium, and residual alkalinity.

By adjusting the mineral profile of the water, brewers can influence the flavor balance of the beer and the pH of the mash, wort, and final beer. Lower pH levels result in brighter and more attenuated beer flavors, while higher pH levels create softer and rounder flavors. The app also allows for the saving of source water profiles for future use.

In addition to salt additions, the app also calculates acid additions to reduce alkalinity and pH. It provides step-by-step instructions for treating both the mash and sparge water, as well as separate sparge water acidification if necessary.

Palmer's Brewing Water Adj App is a valuable tool for brewers looking to fine-tune their brewing waters to achieve the best flavor profiles for their beer recipes. Whether you're a professional brewer or a homebrewing enthusiast, this app can help you create the perfect brewing water for any beer style.
