What Brewer adds
Unlimited recipes
Free keeps 25 recipes. Brewer keeps every one you design, copy or import.
Auto fix
When a recipe drifts off style or off your targets, one tap puts it back in the style's range, holding what's already right.
Brew from what you have
Keep your malt, hops and yeast in BrewBat. It shows which recipes you can brew now, which styles your shelf suits, what to buy and the closest stand-ins you already hold. Brew something and it comes off your stock.
Bring your recipes
Import from Brewfather, BeerSmith, Grainfather or any app that exports BeerXML. Every malt, hop and yeast is matched to BrewBat's catalogue, the numbers are worked out again and each recipe is fitted to your kit, ready for Style Match and Auto fix. And you can export them again any time.

Free
What every brewer gets
Built on 125,000+ published recipes, 1,000+ malts, 440+ hops and 1,200 yeasts.
A recipe in a few clicks
Pick a style, nudge a slider, press Create. A typical recipe for the style, built from 125,000+ real ones and sized to your kit.
Classics and clones
A classic for more than 90 styles and clones of nearly 100 well-known beers, copied onto your kit with your own water.
Brewing water, handled
Your water from 3,000+ reports near you, and the salts and acid that land the mash pH. No ppm tables.
Brew day help
Enter your readings as you go. Running low? It says how much longer to boil or how much extract to add, and learns your kit.
Know how it'll taste
A flavour flower from what the maltsters, growers and labs say about each ingredient, with mouthfeel from the recipe's numbers.
Fruit, spices and the rest
Cherries in a stout, coriander in a wit, a fining for clearer beer: see what the style's brewers add, how much and when. Fruit's sugar counts towards the strength.
Smart swaps
Out of a hop, malt or yeast? Get the nearest substitutes, by flavour, origin and the styles they're brewed in, from your own stock first.
Yeast, sorted
How many packs to pitch, a starter when you need one, and a fermentation plan for the yeast and style.
Packaging
Bottles or keg: the priming sugar for the fizz you want, or the pressure to set.
Scale anything
Change the batch size or switch kit and the whole recipe follows.
Share and print
A brew day sheet to print, a link to share, and your recipes as BeerXML or a full backup.
Fermentation log
Gravity and temperature on one chart, against the gravity the beer should finish at.
Your units
Metric or imperial, litres or gallons, °C or °F, EBC or SRM: each brewer sees their own.
Style Match
A score for how close your recipe is to its style, and where it sits among the six styles nearest to it.
The right amount, added for you
Add a malt or hop and BrewBat proposes how much from the style's recipes, and keeps the strength or bitterness where it was. Take one out and it does the same.
Malt limits
A malt past what its maltster or the style's brewers would use goes red, with how far to cut it back.
Planned to packaged
Each recipe shows where the beer is, from planned to brewed, fermenting and packaged, and locks once it's in the bottle so the record stays true.
Questions
How does the free trial work?
Every new brewer gets Brewer's features free for 30 days, with no card. You keep Free's 25 recipes while you try it. When the trial ends you're on Free unless you choose Brewer.
What happens to recipes past 25?
Nothing is deleted. On Free, your newest 25 stay editable and the rest are read-only: you can still open, print and export them. Move to Brewer and they're all editable again.
Can I cancel?
Any time, from your account. Brewer runs to the end of the year you've paid for, then you're on Free.
Who takes the payment?
Polar, our payment provider. They handle the card and any VAT or sales tax, which is included in the price.
