Grain bill in. Gravity, bitterness and color out.

A recipe calculator that lives in one file on your computer. No subscription, no account, no ads, no server that goes away. Open it, build the beer, print the brew sheet.

WHAT IT CALCULATES

• OG from the fermentables and your efficiency, FG from attenuation, ABV
• IBU by Tinseth, per addition, with boil, first-wort, whirlpool and dry-hop handling
• Color in SRM by Morey, with a swatch
• BU:GU balance
• Strike water volume and temperature, sparge water, total water
• Pre-boil, post-boil and into-fermenter volumes from your boil-off and trub loss
• Priming sugar in grams for the CO2 volumes you want, corn sugar or table sugar
• Style check against 20 common styles: OG, FG, IBU, SRM and ABV in or out of range
• Plain warnings: too much crystal, too much sugar, sweet or harsh balance, strike water too hot

WATER CHEMISTRY

• Type your source water from the report, then grams of gypsum, calcium chloride, Epsom salt, canning salt and baking soda
• Out: the resulting calcium, magnesium, sodium, chloride, sulfate and bicarbonate, the sulfate-to-chloride ratio with a hop-forward, balanced or malt-forward verdict, residual alkalinity and an estimated mash pH with the lactic acid to correct it

YEAST PITCH

• Cells needed for the gravity and volume at ale, hybrid or lager rates; cells you have after viability loss by age; the starter size in litres and grams of DME, or the number of fresh packs
