The Brewery

It all started with a Brewie B20 we bought through crowd founding 2015/2016(?). It took many years before we even fired it up and made our first beer in the autumn 2020. It did not take long before we started to modify it heavily and now there is not much left of the Brewie, actually the only thing left is a pump.

The system is heavily automated and anything that can be made in-house is, from software to hardware.

The system is in constant development so static images below is not always up to date.

System overview

From left to right: HLT, MLT, Boil

The system is a three kettle HERMS system capable of producing about 80L of wort.
Kettles and most of the stainless stuff is bought from Craft Hardware in Germany, we just love their great support and amazing quality products!

Temperature stability in MASH kettle (example). The temperature in mash is within 0.1c of target

The Brain and software

The firmware is python based and runs on a Raspberry pi together with a lot of peripherals, some of them linked further down.
The firmware advertise itself as a MQTT device and is integrated in Home Assistant (HASS) where the GUI is built. The firmware is autonomous and can run all the important stuff like temperature control and safety features without HASS if network goes down. Literally all of the GPIOS of the RPi is occupied!

Messy and not really complete. But you get the picture 🙂

The firmware and GUI is under constant development and unfortunately we don’t have screenshots from a real brew, but maybe there will be.

Everything we’ve learned from developing this brewing system has been incorporated into our advanced LoniBrew™ controller, bringing professional-grade precision and automation to brewers of all scales.
