The Complete Brewing Calculator & Batch Tracker for Beer, Cider & Mead
Homebrewing rewards precision — a few grams of priming sugar too many, a hydrometer reading taken at the wrong temperature, or a hop addition timed off by ten minutes, and the batch you spent a month waiting on doesn't turn out how you planned. Most brewers end up juggling a phone calculator, a printed formula sheet, and a notebook. HomeBrew Batch Pro puts the real formulas — the ones professional brewing software uses — in one offline tool built for the kitchen counter or the brew day table.
Every calculator is built on established brewing science: the Tinseth utilization formula for IBU, the standard residual-CO2 model for priming sugar, and the calibration-temperature hydrometer correction used by BJCP judges. No guesswork, no rules of thumb pulled from a forum post.
Build unlimited recipes with fermentables, hop schedule (amount, alpha acid %, boil time), yeast, and target OG/FG. Every recipe auto-calculates estimated ABV and IBU as you type.
Enter OG and FG to get instant ABV and apparent attenuation — the two numbers every brewer checks first.
Add multiple hop additions with weight, alpha acid % and boil time. Uses the industry-standard Tinseth utilization formula, the same one used by BeerSmith and professional brewing software.
Get the exact grams of priming sugar for your target carbonation level, corrected for the residual CO2 already dissolved at your beer's temperature. Supports corn sugar, table sugar and DME.
Took a reading with a hot sample? Correct it back to your hydrometer's calibration temperature so your gravity readings are always accurate.
Scaling a 19L recipe up to a 23L keg batch, or down to a 5L test batch? Scale every ingredient in one click.
Track every active batch from pitch day to bottling — log gravity readings over time, watch attenuation progress toward your target FG, and see days-since-pitch at a glance.
Track grain, hops, yeast and sundries on hand with low-stock alerts, so you know exactly what to buy before your next brew day.
Built-in OG, FG, ABV, IBU and SRM target ranges for 24 common beer, cider and mead styles — from Pilsner to Imperial Stout to traditional mead.
Every bottled batch is archived with final ABV, rating and tasting notes. Export your full brewing history as a CSV any time.
