Brew better beer with Brew Logic — the all-in-one homebrewing companion built for your garage, basement, or anywhere you brew. No internet required.

REAL-TIME RECIPE BUILDER Design recipes from scratch and watch your stats update instantly. Original Gravity, Final Gravity, ABV%, IBU, and SRM are calculated live as you add and adjust ingredients. Match your recipe against 150+ official BJCP 2021 style guidelines with visual gauges that show exactly where you stand.

MASSIVE INGREDIENT DATABASE Access 150+ fermentables, 30+ hop varieties with alpha acid ranges and aroma profiles, and dozens of yeast strains with attenuation and temperature data — all available offline and fully searchable.

8 QUICK CALCULATORS Skip the spreadsheet. Get instant answers for the brew-day math that matters: • ABV & Attenuation — advanced alcohol and calorie estimates • IBU Estimator — Tinseth, Rager, or Garetz formulas • SRM Color — visual color preview from your grain bill • Priming & Kegging — sugar amounts for bottling or CO2 PSI for kegging • Yeast Pitch & Starter — cell counts, pitch rates, and starter sizing • Water Adjustment — match ion profiles like Burton-on-Trent or Pilsen • Strike Temperature — nail your mash temp every time • Efficiency & Volume — plan for brewhouse efficiency and system losses

INTERACTIVE BREW DAY GUIDE Step-by-step checklists walk you through mash to pitch. Track your gravity readings, correct hydrometer samples for temperature, set timers, and attach notes or photos to each batch. Flip on Theater Mode for a hands-free, big-type brew day view you can read from across the kettle — no more squinting at your phone with wet gloves.

WATER LAB Dial in your water chemistry with precision. Enter your source water ions, calculate exact salt additions (Gypsum, Epsom, and more), and monitor your SO4:Cl ratio to balance malt and hop character.

BREW COACH Smart recipe guidance that reads your recipe and flags issues before brew day. Brew Coach spots off-style bitterness, gravity that misses your target range, and pitch-rate shortfalls — so you fix problems in the app, not in the fermenter.

SHARE & CELEBRATE Turn any recipe into a beautiful shareable recipe card. Watch your beer come to life with live visualizations — a filling pint glass, your grain bill breakdown, and the hop bittering curve. Your brewer journal tracks every batch, unlocks achievements, and wraps it all up in a personal year-in-review.
