Pick a style, get a proven recipe, scale it to your batch size — or build your own from scratch in Advanced mode.
Click any beer style card below. Each one has a proven, ready-made recipe — you don't need to know anything about malt or hops to start.
Type how many liters you're brewing (e.g. 20 L). Efficiency and grain temperature have sensible defaults — leave them as-is unless you know your own equipment's numbers.
You'll get an exact shopping list (kg of malt, grams of hops), a full step-by-step brew day (water amounts, mash temperature, hop timing), and the expected results (OG/FG/ABV/IBU/SRM — see what these mean below).
Don't have the exact hop listed? Use the dropdown next to it — the calculator picks a close substitute and adjusts the weight automatically to keep the same bitterness.
"Save recipe" keeps it in your browser (free plan: up to 3). "Download PDF" gives you a printable sheet to take with you on brew day.
OG — starting sugar density, measured before fermentation. FG — density after fermentation finishes; compare it to this number to know when your beer is done. ABV — final alcohol strength. IBU — bitterness level (higher = more bitter). SRM — color, from pale straw to near-black.
Advanced mode is for building a recipe completely from scratch — you'll need to know your own malt and hop numbers (°Lovibond, extract potential, AA%). Stick with Beginner mode if that sounds unfamiliar.
Ten proven styles to start with. Styles marked "takes patience" need a lager fermentation or a fussy yeast strain — great second or third brews.
Dial in calcium, sulfate, and chloride to match your water to the beer style you're brewing. Covers the two most common brewing salts — gypsum and calcium chloride.
Covers Ca/SO4/Cl balance for flavor. Full mash pH and alkalinity modeling (with Mg, Na, bicarbonate, and acid additions) is a deeper Pro-tier tool — this gets you most of the way there for most beers.
Dial in Ca, SO₄, and Cl to match your water to the style you're brewing. This is a Pro feature.
