ABV, grain bill, IBU, yeast pitch rate, priming sugar, and recipe scaling calculators.
Calculate alcohol by volume (ABV) from your original gravity and final gravity readings. Uses the standard ABV formula plus alternate methods for high-gravity beers.
Calculate how much grain you need to hit your target original gravity for a given batch size and brewhouse efficiency.
Calculate International Bitterness Units from hop additions using the Tinseth formula. Accounts for alpha acid percentage, boil time, and wort gravity.
Calculate the optimal number of yeast cells to pitch based on wort gravity, batch size, and beer style. Covers both ale and lager pitch rates.
Calculate mash water, sparge water, and total water volumes for all-grain brewing. Accounts for grain absorption, boil-off, and trub loss.
Calculate the right amount of priming sugar for bottle carbonation. Supports corn sugar, table sugar, and DME with temperature-based CO2 adjustment.
Scale any beer recipe up or down to a different batch size. Automatically adjusts grain, hops, yeast, and water volumes while maintaining ratios.
Design balanced cider blends from sweet, sharp, bittersweet, and bittersharp apple varieties. Get volume breakdowns, expected gravity, and flavor profile.
Calculate honey, water, and yeast needs for mead based on target gravity, batch size, honey variety, and desired sweetness level.
