BrewIon Water

BrewIon Water Lab is a hands-on brewing-water chemistry and salt-treatment studio for all-grain homebrewers and nano-brew pilots. Turn a municipal or well report into a style-true ion profile before mash-in—deliberate chemistry instead of guesswork or a thin one-screen calculator. CORE WORKFLOW Enter source ions → lock a classic or custom style target → balance residual alkalinity and predicted mash pH against grain color → dose gypsum, calcium chloride, salts, and acids in grams → compare the sulfate-to-chloride taste ratio → export one treatment card for brew day. SOURCE-WATER ION PAD Log Ca, Mg, Na, sulfate, chloride, and bicarbonate/alkalinity from a lab report or utility sheet. Toggle ppm vs. grains-per-gallon with live validity highlights on out-of-range values. STYLE-TARGET BAY Seed profiles for Pilsen, Munich, Dortmund, Vienna, Burton-on-Trent, Dublin, Edinburgh, London, residual-alkaline amber, and soft NEIPA water—each with target ion bands and one-tap Apply Target. RA & MASH-pH ESTIMATOR Combine source alkalinity with grain-bill color (SRM/EBC quick chips for pale, amber, brown, stout) to show a predicted mash pH band and whether acid or alkaline correction is needed. SALT-AND-ACID DOSING MIXER Adjust gypsum, CaCl2, Epsom, NaCl, baking soda, chalk, lactic, and phosphoric additions in grams for your strike volume. See live ion deltas, an SO4:Cl taste-ratio badge, and caution chips for over-salting. STRIKE & SPARGE PLANNER Set mash thickness (qt/lb or L/kg), grain weight, boil-off, and kettle losses to compute strike water, sparge water, and pre-boil volume that feed the dosing math. SPARGE ACIDIFICATION HELPER Get acid type and mL recommendations to pull sparge water toward a chosen pH without stripping the mash, with resulting sparge alkalinity on a layered gauge. BEFORE/AFTER CHARTS Ion radar and bar charts compare source vs. treated profile against locked style bands, with color-coded deficit and excess wedges for each ion. TREATMENT-CARD COMPOSER Name the water plan, stamp style, volumes, gram doses, and predicted pH, preview a brew-day card, then share as image or PDF cut-sheet for the brew stand. SAVED PLANS & STARTERS Four complete starter builds ship day one: soft Pils skeleton, Burton pale boost, Dublin stout lift, and NEIPA chloride-forward. Every plan opens fully editable. OFFLINE GLOSSARY & WIDGET Plain-language cards explain what each ion does to malt and hop perception, safe practical ranges, and ppm ↔ g/gal conversion. Pin the active plan’s target style, SO4:Cl ratio, and top three salt doses on the Home Screen with WidgetKit. PRIVACY-FIRST All chemistry data stays on-device (SwiftData). No account gate and no network required at launch. In-app Privacy Policy and Terms of Use are always available in Settings. Built for brewers who want a complete pre-brew water desk—not a brew-day diary and not a generic recipe browser.
