See BrewMaster in Action
Describe the beer you want — "something like a hazy IPA, not too boozy" — and get back a recipe with its numbers checked against the style. Then brew it: a step-by-step brew day with timers and hop alerts, a fermentation log, tasting notes and printable sheets. The AI runs on your own computer, and your recipes never leave it.
Talk through what the beer is for, the style or a beer you like, strength, bitterness, color, flavors and your setup. Aegis fills in a brew brief and drafts a recipe — all-grain, brew in a bag, partial mash or extract.
OG, FG, ABV, IBU (Tinseth or Rager), SRM color, BU:GU and style fit recalculate as you edit. Fermentables, hops from mash to dry hop, yeast with pitch rate and starter advice, and your own equipment profiles.
Steps generated from the recipe, with planned values beside fields for what actually happened. The boil timer calls out every hop addition. Kitchen mode goes full screen with big type and a number pad.
Strike water, brew-in-a-bag water, step infusions, priming sugar and keg pressure, dilution and boil-off, refractometer and hydrometer corrections, pitch rate and starter size — no recipe needed.
Log gravity, temperature and pH over the following days and chart them against the expected FG. Score each batch on BJCP-style tasting sheets and watch how it changes as it conditions.
Every recipe with full revision history, clones that remember their parent, and BeerXML 1.0 in and out. Print recipe, brew-day and tasting sheets to PDF on Letter or A4.
Recipe software usually opens with an empty grain bill. Aegis starts by asking about the beer instead — one topic at a time, in your own words — and turns the answers into a brief you can see and correct before it drafts anything.
Each entry on the brew brief is marked as something you said, something Aegis inferred, or a style default. Inferred values are read back for you to confirm.
The model proposes ingredients; the calculator works out the numbers. If OG, IBU or color misses the style, the draft goes back for one correction, and unfamiliar ingredients are flagged.
A side panel answers questions about the open recipe and your batches — low OG, a tasting you want to improve — and proposes changes. Nothing changes until you accept.
Starting brew day snapshots the recipe, so later edits never rewrite what you actually brewed. Every step saves as you go — close the app mid-boil and nothing is lost.
Gather and weigh, strike water, mash rests, sparge, the boil with every addition, whirlpool, chill, OG, pitch — then dry hops, cold crash and packaging. Timers keep running when you switch pages.
Its own water plan and steps: kettle fit with a dunk sparge when the mash won't fit, strike temperature for a full-volume mash, heating time at your burner's rate, and the weight of the wet bag you're about to lift.
Measured gravities and volumes give your actual efficiency and projected ABV. Put that back in your equipment profile and the next recipe hits its numbers.
Estimates, not guarantees. The calculator uses standard brewing formulas, and the bundled BJCP 2021 style ranges and ingredient values each carry their source and date — your system will differ, so measure on brew day. Hot wort, pressure vessels and over-primed bottles are real hazards; the built-in guide includes a brewing safety page.
The language model runs locally through Ollama, and your recipes, batches and tastings live in a SQLite file on your computer. A remote AI host is refused unless you allow it.
No sign-up, no cloud sync, no analytics. Settings has one-click options to delete chat history or wipe all data.
Every feature, no charge and no license key. Export any recipe to an .aegisbrew
file, BeerXML or a PDF whenever you like.
Aegis BrewMaster is in Beta and free to use. On Linux you can install it in one command:
Prefer a traditional package? A Debian/Ubuntu .deb is on the download page.
The brainstorm and assistant need Ollama and a local model. The default model runs on an 8 GB laptop without a GPU:
No Ollama? The recipe editor, calculators, brew day, tasting notes and library all work without it.
Go to DownloadNote on licensing: Aegis BrewMaster is free to download and use during the Beta, with every feature available. After the Beta, some features may require a one-time license purchase — pay once, never a subscription. The software is proprietary and licensed, not sold.
