Most homebrewers know water chemistry matters. They've read the articles, they've seen the Bru'n Water spreadsheet, they understand that the same recipe tastes wildly different in Orlando vs Portland vs Dublin. And most of them skip it anyway — because the alternative is buying five bags of salts, learning a chemistry subject, and weighing grams on a kitchen scale that isn't accurate enough. Brew Foundations replaces all of that. Each pouch is a single-use, pre-measured blend formulated to hit the target water profile for a specific beer style when dosed into 5 gallons of RO or distilled water. Five seconds of prep instead of five minutes of weighing, and your beer tastes the way the style is supposed to taste.
