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.

  • Venturi pipe for flow measurements

    Venturi pipe for flow measurements

    As we were going through the brewery’s hose system and replacing the sanitary valves, we also found the need to upgrade our flowmeter to a larger size. We started from the same theory as the previous version but made it more robust and, most importantly, designed it for higher flows. With the old venturi pipe,…

  • Pneumatic pinch valves

    Pneumatic pinch valves

    Due to our constant pursuit of enhancing our system, we began reevaluating hoses and flows within the brewing system. The design of the previous servo-pinch valves had dictated the placement of the valves and consequently the routing of all hoses within the system. Unfortunately, the valve placements often necessitated unnecessarily long hoses. During the optimization…

  • CIP-lid for the brewery

    CIP-lid for the brewery

    We use a CIP-ball for the fermenter and it works really great. We would like to use CIP on our kettles as well and we made this modification to a spare lid we had so that we could use the same CIP-ball for the brew kettles. The pump used is a submersible water pump (intended…

  • Steam condenser

    Steam condenser

    We do our brews in a garage, a large private garage but we do not want to destroy the ceiling so we have invested in a capable steam condenser for the boil kettle. It works really great!

  • Sparge arm/mash manifold

    Sparge arm/mash manifold

    We have used the “standard” sparge arm that is designed for the MLT but we wanted something that was more dynamic and gave room for stirring the bed if necessary so we designed a ring of 12 mm SS tubing with a quick connector tee that the mash inlet connects to. The ring is held…

  • Digital “suction” sensor

    Digital “suction” sensor

    Many brewers use manometers or clear hoses at the bottom of the MLT to monitor the pressure below the grain bed. We have taken it to the next level and put a differential pressure sensor (1 psi range) between the bottom and top of the MLT to be able to digitally monitor and log the…

  • The servo valves (OLD)

    The servo valves (OLD)

    These valves are now retired and replaced with Pneumatic pinch valves. About the only thing we salvaged from our first brewery, the Brewie B20, was the servo valves for 16×12 mm silicone hose. They are actually what makes our system so automated today. They pinch the hose to close and are therefor very sanitary and…

  • Temperature sensor system

    Temperature sensor system

    We use six temperature sensors in the brewery for measuring the We use 1.5″ thermo wells for HLT, mash bottom and boil, and custom built sensor probes for mash inlet and outlet (after cooler).The reason for using custom probes is that the thermo wells ads latency to the measurement system that is not desirable for…

  • DIY Counterflow Cooler (old)

    DIY Counterflow Cooler (old)

    At first we used a plate heat exchanger but they are a pain to clean and not very effective so we made our own counterflow cooler out of 9 m of 12 mm copper tubing, some reinforced PVC hose and some pipe fittings. We wrapped grass trimmer cord around the pipe to delaminate the flow…

    Venturi pipe for flow measurements (OLD)

    This system is now updated with a bigger version! We started with a traditional flow sensor with an impeller but it was not accurate enough and was kind of invasive, especially when there was grains stuck in the impeller 🙂 Being physicists at trade we remembered something about differential pressure over a narrowing of a…
