The Story

The Brewmaster and the Personal AI Assistant

Gerhard, the brewmaster

Gerhard

68 years old. Runs eibachbraui, a micro brewery in Gelterkinden, Switzerland. Certified Biersommelier, 2x Gold and 2x Silver at the Brau & Rauch Beer Contest. Knows everything about beer. Knows nothing about AI.

OpenClaw, the AI agent

OpenClaw

A personal AI assistant that actually does things. Open source, runs 24/7 on its own computer, and talks to you via WhatsApp or Telegram. Knows everything about automation. Knows nothing about beer.

Frontira, an AI & automation company, had an idea: connect Gerhard's Grainfather G30 to a MacBook over Bluetooth, point OpenClaw at it, and let them brew together.

One knows beer, the other knows machines.
Together they make Lobster Lager.

The Process

How OpenClaw brews

The claw suggests. The human decides.

📝
Step 01

Define the Recipe

The brewer sets the grain bill, hop schedule, and fermentation profile. OpenClaw converts it into a machine-readable brew plan.

📡
Step 02

Connect via BLE

A MacBook connects to the Grainfather G30 over Bluetooth Low Energy. The bridge reads sensors and sends commands in real time.

🌡️
Step 03

Brew with Guardrails

OpenClaw manages temperature ramps, step mashing, and the boil schedule. The brewer monitors and approves each transition.

👁️
Step 04

See with Vision

A camera watches the kettle. OpenClaw reads the display, checks foam levels, and visually verifies each step. BLE for control, vision for confirmation.

📊
Step 05

Log Everything

Every temperature reading, every pump toggle, every timer event is recorded. The complete brew session becomes a reproducible dataset.

Idea

The idea is born

Somewhere around kilometer five of a morning run, the idea clicked: what if we let an AI agent brew a beer? Not as a gimmick, but as a real proof of concept. Gerhard has the brewery, Frontira has the AI tooling, and OpenClaw can talk to hardware over BLE. By the end of the run the name was set. Lobster Lager. Hold my claw.

Tech

First BLE connection to Grainfather

Prototype day. Connected a MacBook to Gerhard's Grainfather G30 over Bluetooth Low Energy for the first time. Read live sensor data, toggled the pump, sent temperature commands. The bridge works. OpenClaw can see and control the hardware. Everything we need for a fully automated brew day.

Recipe

Recipe finalized with Gerhard

Sat down with Gerhard and dialed in the recipe using kleiner-brauhelfer. An Amber Lager built on Pilsner and Munich malts, with Caramel Amber and Melanoidin for depth. Mandarina Bavaria for a citrus edge, East Kent Goldings for earthy balance. 24.5 liters, 4.6% ABV, 20 IBU. Batch #001 is locked.

Test Brew

First test brew: mash running

Fired up the Grainfather for the first test run. OpenClaw managed the full mash schedule through the Brew Dashboard. Einmaischen, Maltoserast at 63 °C, all steps automated. Pump on, heater on, temperature holding steady. The system works end to end.

OpenClaw gets eyes

Gerhard mounted a camera next to the Grainfather. OpenClaw can now visually monitor the brew process, reading the display temperature and checking foam levels during the boil. BLE for control, vision for verification. The claw sees everything.

brewOS gets stats and vision

Major dashboard upgrade. The Brew Dashboard now shows live brew stats, step history, and integrated vision feedback. Clawdbot, the Telegram bot, walks the brewer through every action: start, acknowledge, skip, abort. OpenClaw doesn’t just control the hardware anymore. It explains what’s happening and why. The full brew operating system is taking shape.

Final recipe locked: #001

Gerhard finalized the recipe in kleiner-brauhelfer. Munich Malt bumped to 23%, Caramel Amber replaces Caramel Dark, East Kent Goldings take over the late hop additions. The grain bill is tighter, the hop schedule cleaner. Recipe #001 is the one that goes into the fermenter on Saturday.

Tech

Brew program test: full run

Gerhard ran the complete brew program through brewOS. Vorheizen, Einmaischen, Maltoserast, Verzuckerung, Abmaischen, 90-minute boil with all four hop additions. Clawdbot confirmed every state transition via Telegram. The system ran end to end without manual intervention. The program is ready.

T-minus 48 hours

Recipe locked. Brew program tested. Ingredients weighed. Grainfather cleaned. Saturday at 9:00, Gerhard starts the program and OpenClaw takes the mash from grain to fermenter. 24.5 liters of Amber Lager. Everything is ready.

Brew Day

Brew Day: Batch #001

The real deal. 08:26, Gerhard starts the program. OpenClaw takes control of the Grainfather over BLE. Einmaischen at 64 °C, Maltoserast at 63 °C for 35 minutes, Verzuckerung at 72 °C, Abmaischen at 78 °C. brewOS manages every step transition, every hop addition. Mandarina Bavaria goes in as Vorderwürze, then East Kent Goldings and Fuggles at 75 and 85 minutes before end of boil. 90-minute boil at 100 °C. The full brewery is running: Grainfather G30 on the balcony, glycol chiller cooling, wort chiller coiled and ready. 24.5 liters of Amber Lager, grain to fermenter, managed by an AI agent.

brewOS runs its first real batch

The Brew Dashboard ran the entire Batch #001 session live. Recipe Lobster Lager 1 (Nr. 201), five mash steps, four hop additions, 90-minute boil. Temperature tracking, timer countdown, hop schedule with confirmation buttons. Every addition acknowledged in real time. The system that started as a prototype two weeks ago just brewed a real beer.

Fermentation begins

Wort cooled and transferred to the Grainfather conical fermenter. Yeast pitched, temperature set to 12 °C. The glycol chiller holds it steady. Within hours the fermenter reads 11.3 °C and the heater kicks in to maintain target. Batch #001 is alive. Now we wait.
