LabBrew: Beverage Recipe Diary

Brewing is chemistry, and one guessed figure can spoil a batch. Scribbled notebooks, scattered spreadsheets and half-remembered gravity readings cost you sharp beer — and sometimes a whole fermenter. LabBrew keeps every reading, timer and calculation for the batch in one place, so the maths is finished before the wort has cooled. A single logbook and a complete calculator suite for every brew, from grain bill to glass. BATCHES & FERMENTATION - Follow active and conditioning batches with live day counts - Record gravity readings and watch the drop chart fall towards target FG - Attenuation and ABV recalculate as you log each sample BREW DAY TIMER - Guided mash, sparge, boil and whirlpool stages - High-resolution hop-addition alerts so bitterness and aroma land on cue - Hold-temperature prompts for every mash step RECIPE & CALCULATORS - Estimate original gravity and beer colour (SRM) from your grain bill - Tinseth bitterness model for predictable IBU - Priming-sugar maths for safe, repeatable carbonation - Hydrometer and refractometer converter with temperature correction YEAST & CELLAR - Strain library with ideal fermentation temperature ranges - Malt and hop store with alpha-acid tracking - Low-stock flags so you reorder before brew day SANITATION & TASTING - Equipment sanitation checklist to keep infection out - Tasting passport to grade head, body, aroma and finish on every batch BUILT FOR - All-grain and BIAB brewers optimising efficiency - Extract beginners getting to grips with the numbers - Lager and ale brewers managing strain temperatures - Anyone bottling who wants carbonation without bottle bombs Measure once, brew with confidence. LabBrew keeps the chemistry honest, batch after batch.
