Origin_Story

The Brewmaster and the Personal AI Assistant

Gerhard, the brewmaster

Gerhard

Retired brewmaster. Runs eibachbraui, a microbrewery in Gelterkinden, Switzerland. Certified beer sommelier, 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.

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

And then Stefan came, with the idea to connect Gerhard's Grainfather_G30 to a MacBook over Bluetooth, point OpenClaw at it, and let them brew together.

Stefan Erschwendner, the Initiator

Stefan

The Initiator. Founder of Frontira and Valhalla Venture Group. Connected the brewmaster with the AI builder to bring intelligence out of the terminal and into the physical world.

🍺

Beer Sommelier

Certified beer sommelier since 2021.

🏅

Award-Winning

2x Gold, 2x Silver at the Brau & Rauch.

✅

What is OpenClaw doing?

OpenClaw was invented by Peter Steinberger, a renowned developer and friend of Stefan Erschwendner.

Both hailing from beer-loving Austria, sharing a mutual vision that all repetitive work in real-life should be done by AI agents.

Lobster Lager is using OpenClaw to brew beer, a show case you can tell your friends about.

The OpenClaw Agent
  • Inventor: Peter Steinberger
  • Hired by: OpenAI (ChatGPT)
  • Origin:Austria (Europe)
  • Mode:Working with Humans
  • Status:Brewing...
SYSTEM: BREW_OS v1.0.4

How OpenClaw Brews

$ The claw suggests. The human decides.

TERMINALtail -f /var/log/brew.log
STEP_01
> define_recipe.sh

The Prompt

Brewer sets grain bill, hop schedule. OpenClaw compiles to machine code.

STEP_02
> connect_ble --device g30

The Bridge

MacBook connects to the Grainfather via BLE. Real-time telemetry established.

STEP_03
> execute_mash_profile

The Control

OpenClaw manages temp ramps and pump cycles. Human monitors guardrails.

STEP_04
> enable_vision_sys

The Eyes

Computer vision verifies kettle states and foam levels. Double confirmation.

STEP_05
> export_telemetry

The Data

Every sensor read logged. The brew session becomes a reproducible dataset.

The Lobster Lager Founder

Stefan Erschwendner

As the Founder of Frontira International and Valhalla Venture Studios, Stefan has spent his career at the intersection of deep tech and real-world business value.

Lobster Lager isn't just a beer. It's a proof of concept. It demonstrates how autonomous AI agents can be trusted with physical, time-sensitive processes where precision is critical.

To craft a tangible show-case for both AI enthusiasts and forward-thinking managers, Stefan initiated this project to bring AI out of the terminal and into the physical world.

Event

ClawCamp Berlin: Gerhard takes the highlight session

Gerhard delivered ClawCamp Berlin's 6:00 p.m. highlight session at CODE University of Applied Sciences. At 68, he told the Lobster Lager story in his own words: how he turned decades of brewing experience into brewOS through experimentation with OpenClaw, while remaining the human in the loop for every physical brewing decision. He ended with 24 bottles at the bar. His verdict afterwards: “Voller Erfolg.” The feedback on the beer: “Nur positiv.”

Gerhard is Handelsblatt's Entrepreneur of the Day

Handelsblatt, Germany's leading business newspaper, published a two page profile of Gerhard and Lobster Lager. The story follows Gerhard from his microbrewery in Gelterkinden to Jensen Huang's NVIDIA keynote and names him its Entrepreneur of the Day. More than a beer story, it is about curiosity, domain expertise and learning to build with AI at any age.
