Brewtarget is a free, open-source homebrewing software for macOS (and other platforms) that lets you design, calculate, and refine beer recipes before a single grain gets milled.
What is brewtarget?
Brewtarget is a desktop application built specifically for homebrewers who want rigorous, number-backed control over their recipes. Where most note-taking apps leave you scribbling on paper or wrestling with spreadsheets, Brewtarget gives you a dedicated environment that understands the chemistry of beer — it speaks in IBUs, SRM, OG, FG, and ABV natively, so you spend less time converting and more time actually brewing.
The project is actively maintained and distributed free of charge, making it one of the more generous tools in the homebrewing space. I've had it open on my MacBook during nearly every brew day this quarter, and it earns its place in the dock.
What does brewtarget do best?
Brewtarget excels at recipe formulation with real-time calculation feedback — adjust your grain bill by 100g and every downstream number (gravity, colour, estimated efficiency) updates instantly. That tight feedback loop is genuinely useful when you're trying to nail a specific style to BJCP guidelines.
- Full brew-day workflow: mash profiles, sparge volumes, boil additions, and fermentation targets all live in one record.
- Style guidelines built in: select a target style and the app flags whether your recipe is in range for every relevant parameter.
- Ingredient database: a bundled library of malts, hops, yeasts, and water profiles means you're not sourcing reference data from five browser tabs.
- BeerXML support: import and export recipes in the industry-standard BeerXML format, so nothing you build is locked to this one app.
- Equipment profiles: model your actual kettle, mash tun, and losses so volumes predicted by the software reflect your real kit, not some idealised brewery.
The water chemistry module is where power users will spend serious time. Building a water profile from scratch and watching it influence mash pH is the kind of feature that separates dedicated brewing software from a generic spreadsheet.
Is brewtarget free?
Yes — Brewtarget is completely free to download and use. It is open-source software, and there are no premium tiers, subscriptions, or feature paywalls. You get the full application at no cost, which is remarkable given the depth of its calculation engine.
Who should use brewtarget?
Brewtarget is best suited to homebrewers who have moved past the kit-in-a-box stage and want quantitative control over their process. If you're still extract brewing from kits, the full feature set may feel like overkill — but if you're doing all-grain batches and chasing precise style targets, this tool pays off quickly.
It's also a solid choice for anyone frustrated with cloud-based alternatives like Brewer's Friend or Brewfather who'd rather keep their recipe library local, offline, and under their own control. There's something satisfying about a tool that works entirely without an internet connection.
How does brewtarget compare to Brewfather and Brewer's Friend?
The clearest difference is the local-vs-cloud divide. Brewfather and Brewer's Friend are browser-based SaaS tools with polished mobile apps and cloud sync; Brewtarget is a native desktop application with no subscription and no server dependency. For brewers on a tight budget or those who are privacy-conscious, Brewtarget wins on both counts.
Where the cloud tools pull ahead is convenience — Brewfather in particular has a slicker modern UI, integrations with online homebrew shops, and a well-maintained iOS app for checking numbers on brew day. Brewtarget's interface is more utilitarian, a reflection of its open-source roots. I wouldn't call it ugly, but it doesn't have the visual polish of a commercial product. That said, the calculation engine is solid and the BeerXML interoperability means you can always migrate your recipes if your needs change.
What are the best brewtarget alternatives?
The strongest alternatives depend on how you prioritise cloud access versus local ownership:
- Brewfather — the current crowd favourite for cloud-based brewing; beautiful UI, mobile app, shop integration. Free tier is limited; paid subscription unlocks full functionality.
- Brewer's Friend — long-standing web tool with a broad recipe database and decent free tier.
- BeerSmith — the veteran paid desktop app; deep feature set, available for Mac, but costs money upfront. Often recommended alongside Brewtarget for users who want a native app with commercial support.
- iBrewMaster — Mac-native option with a cleaner UI, though less actively updated.
If cost is the deciding factor, nothing in this list matches Brewtarget's combination of zero price and full offline capability.
