Cider fermentation with Float

Last month Brewbrain delivered Float Hydrometers to Ad Astra, a cider company in the heart of Somerset, United Kingdom.
The vision of Ad Astra works perfectly with Brewbrain products; traditional cider making, using modern techniques.

To collect more detailed information on the variables in the different fermentations a wireless network with Floats was installed.
This makes it possible to get real time data of the fermentation activity and temperatures of the 15 fermenters!

We are looking forward to see and taste the results of this project.

Log everything! – with the Neuron measurement hub

We will soon start selling the Neuron in stores – a tool that will make your brewing process a walk in the park!

Brewing beer is a complex, time-consuming and delicate process in which every step has a certain purpose and is to be executed with care. Oftentimes making beer is a race against the clock in which an extra hand is very helpful.

To make this process more easy, we developed the Neuron.

Mashing might take up to a few hours and if you deviate too far from the temperature schedule, your brew might not turn out how you want it to. See what’s happening during your mash by using the Neuron to measure temperature at multiple locations in your kettle using multiple temperature probes.

The fermentation process is a cumbersome step which easily takes more than a week. What a waste it would be to mess this up.
Get a better grip on your fermentation by measuring CO2, pH, ORP, and pressure.

So your brew is done, but are you storing it correctly? Measure the humidity and temperature of the room the Neuron is in.

You’ve already got sensors laying around and don’t want to spend money on new ones? Hook up your own analog and/or digital sensors, and record the data to your free My Brewbrain account using the same Neuron.


We currently have the following set available for order in Europe only, for EUR 100 ex shipping:
– 1x Neuron measurement hub, which measures room temperature (acc. ±0.5 °C) and humidity (acc. ±3% RH)
– 1x Power adapter 100- 240 V 50/60 Hz, plug type C
– 1x Food-safe, water-proof temperature probe with 5m cable (acc ±0.5°C, usable from -40 to + 110 °C).
Additional probes are available for EUR 30.

Adjust your Float’s calibration

Brewbrain developed a sophisticated adjustment tool which allows for a multi point offset correction related to the factory calibration. This keeps the original characteristics of the intrument, while the offset gives the opportunity to fine tune the readings.

With an easy to use interface users can now adjust the calibration to meet hydrometer or refractometer readings of their Floats for Free!

To make this possible we developed a brand new firmware for your Float, which can be remotely updated by WiFi. Check out your “My Floats” menu, apply the new firmware and switch to “measure”. Easy!

After 15 minutes switch to “setup” and you will be able to acces the maintenance menu to start calibrating your product.

Check out our manual on re-calibration here!

Brewbrain invested a lot of time and effort to optimise the calibration process in order to deliver the Float calibrated from factory. Being interested in brewing and technical solutions Brewbrain is still developing new methods and improvements to give our clients the best possible user experience and product accuracy.

Float readings can differ from your Glass Hydrometer because of a lot of phenomena in your brew. There can also be changes of the calibration accuracy because of temperature stress and bumping the Float.

With the new calibration adjustment it is possible to match the readings of your hydrometer or refractometer!

Happy brewing!


(Room) temperature data logging

Recently Brewbrain delivered a protoype of a My Brewbrain connected temperature data logger to a user.

As one of our customer was looking into monitoring the temperature of his brewhouse to get a better uderstanding of the impact on his fermenters he contacted us about his idea.
Brewbrain developed the small WiFi connected hub with a onboard temperature and humidity sensor. Next to that up to 3 temperature probes with 5 meter silicone cable are delivered with the system to measure at different positions on the same time.

The data is presented on the free My Brewbrain platform in the same user friendly interface users are used to with the Float Hydrometer.
Check out the readings of the system to get an impression.

New temperature units and SG units on My Brewbrain.

To serve our brewing friends all over the world we developed a new set of temperature units and SG units to present your data in your personal My Brewbrain user account.

From now on you can configure your temperature data and specific gravity data from your user panel! Just click the gear in the left lower corner and check out the custom settings menu. When you select one of the units, a green check mark will appear and you are good to go! Easy!

The available temperature units are Fahrenheit [°F], Celcius [°C] and Kelvin [K]. For SG units, Oechsle [°Oe], Plato [°P], SG [-], Brix [Br] and Klosterneuburger Mostwaage [KMW/Babo] are available.

If you are in need of any other units, please let us know at!

Happy brewing!
