Our journey that became Brewbrain with its digital hydrometers, started in 2017, in the evenings after work. We wanted to combine our love for measuring and creating sensors with brewing beer. I personally love how nature and technology can contrast with each other and at the same time work together in harmony. Brewing is a creative process and, just like making music, you must feel the result you are creating. With that in mind, we set out to improve the brewing process by making products that give more control and insight into what you are doing.

The first Float

We had worked out quite a few measuring principles for tracking the specific gravity of a brew. Do you remember the beerbug? Or PLAATO’s Airlock? We also had this idea back in the day, but it didn’t feel like the best path to take. We were working on a principle that calculated the density from flotation angle and then stumbled upon the iSpindel where this was already done. We assembled a few and quickly thought “brewers want to spend time brewing, not DIY-ing brewing equipment”. Not only was soldering messy, calibration was difficult and often inaccurate and on top of it all you needed to set up your own logging environment. And that is why we created Float: a digital hydrometer that works out of the box with no hassle for the user.

Running a startup

We believed that the Float would make a difference in the brewing scene and took a leap of faith and became a startup. Back then there were four of us, each with a love for engineering and of course: beer. It has been an amazing journey and boy did we learn a lot. Sadly, we have had to part ways with Steve and Bart, but Thijs and I are dedicated to showing the world what our designs have to offer. We have grown a lot and are committed to creating durable products that last. We care for the environment and are grateful for our customers, which is why we do our best to make sure a device keeps working and repair it when possible. We value transparency and will back up the claims we make, so that you can trust the product that you are using.

The step towards Float Pro

The Float digital hydrometer was released in 2020 and we have learnt a lot from our brewers. And so the time was right to create a new version that performs even better and is usable by the pros. Being the nerds that we are, we poured our heart and soul into the design. We wanted to pack wireless charging in there and make the design as smooth as a good beer going down your throat. We felt that when using a digital device with no screen, you need more feedback on what’s going on, so we included a neat multi-color lid that lets the Float tell you if everything is going like it should. We had developed a custom simulation that models at which angle the device Floats, so that we could optimize the weight and center of gravity to get more accurate readings. The housing is sealed by a seamless ring that stays in place due to its unique design. No hassle when (un)tightening the lid and you can trust the seal to do its job when fermenting under pressure.

So, what’s next?

There’s so much more I would like to tell you about the development of this digital hydrometer, so I will, in the upcoming blog posts. Follow our blog for deep dives into all the aspects of the design. We will also be telling you how to get the most out of your Float Pro and we will announce all the updates that we will be giving for the device and our online platform my.brewbrain.nl.

We love to stay in contact with our brewers so feel free to comment on this blog. Or reach out to us via support@brewbrain.nl. We’re there for support and are always welcoming your ideas on what to improve next.

Last but not least: The best wishes for 2026🎉. Make this an awesome year and your beers even better!🍻

Why we love our Float Pro❤️ digital hydrometer

You’ve been using the first Float for quite some time now and you know exactly how to use it to get the best out of your fermentation. But there’s always room for improvement.

We’ve learned a lot from the Float, we’ve used your feedback to create the Float Pro! We’ve optimized for ease of use, so you can brew like a PRO.

Clear color signals, which enable you to tell battery and Wi-Fi status easily!

Surface is smooth all over leaving no room for dirt.

How do they compare?

Key point	Float	Float Pro
Ease of setup	Stable	Faster
Charging	USB micro	Wireless and USB-C
Battery indicator	Indirect	Instant
Time troubleshooting	Moderate	Minimal

Is setting up Float Pro really that easy?

If the Float still meets your standard, there is no need to change!

But if you’re ready to switch to a hassle-free, time-saving version so that you can focus on what’s important, the Float Pro is your next upgrade.

Order the Float Pro now!

People that have used both the Float and the Float Pro experienced:

Easier setup and handling,
Very sleek housing, easy to clean,
Not having to take off the cap to switch modes is really convenient.

We want your upgrade to be worthwhile, and if the Float Pro doesn’t deliver clear value within 30 days, you can return the product and get your money back.

Float Pro – The New Standard in Digital Hydrometers

We are proud to introduce the Float Pro – our completely redesigned digital hydrometer and thermometer that takes fermentation monitoring to the next level.
We didn’t just improve on what was already there; we reimagined the concept of a hydrometer from the ground up.
The result? A robust, smart, and accurate instrument that gives every brewer professional insights.

Meet us at the Dutch Craft Beer Conference

Dear (craft) brewers,

We are proud sponsors and exhibitors at the Dutch CRAFT Beer Conference. We will be attending the fair to meet craft brewers, as we believe we can offer (measurement) solutions tailored to craft brewers as well. We will also show a prototype of our upcoming hydrometer: Float 2, which we believe will be the best digital hydrometer for hobby and craft brewers alike.

So, if you’re attending the fair, please visit us at stand 12, we are open to any questions. We love to create solutions that help you stay in control when crafting your next beverage.

There are still tickets available for the fair, we hope to see you tomorrow!
