What Brewbrain does
Brewbrain B.V. is a Dutch smart brewing technology company headquartered in The Hague, Netherlands. The company designs and sells Wi-Fi connected digital hydrometers—the legacy Float and the flagship Float Pro—that float inside fermentation vessels and continuously measure specific gravity (SG) and temperature, transmitting data wirelessly to a cloud platform (My Brewbrain) so brewers can track fermentation activity in real time without opening the fermenter. The Float Pro, launched in November 2025 as a full hardware redesign, features offline data buffering (up to 170 days of measurements), multi-language setup, and integration with third-party brewing management platforms Brewfather and Grainfather.
The business is primarily a hardware company: revenue comes from one-time unit sales of the Float/Float Pro, distributed direct-to-consumer via brewbrain.nl and through an international reseller network spanning Europe, Scandinavia, Canada, New Zealand, and South Africa, with the My Brewbrain software platform offered free to end users and premium features planned for future monetization. Customer segments are led by home brewing enthusiasts (primary), with secondary reach into craft/professional brewers and cider and wine producers; named commercial deployments include UK cider producer Ad Astra and a co-development partnership with Beer-o-Meter. The company is founder-owned (Bart van der Meer), operates with a 1–10 person team, has no disclosed external funding, and supports growth through a six-language multilingual website, content marketing, social media, and event sponsorships such as the Dutch Craft Beer Conference.

Brewbrain product offering
Product offeringCore offering
Brewbrain designs, manufactures, and sells wireless digital hydrometers (Float Pro and the legacy Float) that measure specific gravity and temperature during beer, cider, and wine fermentation in real time. The devices transmit data to the free My Brewbrain cloud platform, enabling brewers to monitor fermentation activity remotely, store historical brew data, export CSV, and integrate with third-party brewing software such as Brewfather and Grainfather.
Product overview
Brewbrain is a smart brewing tools company offering two generations of digital hydrometers (Float Pro and the legacy Float) paired with the free My Brewbrain cloud platform. Float Pro is the current flagship Wi-Fi hydrometer that monitors specific gravity, temperature, and fermentation activity in real time without opening the fermenter, storing up to 170 days of offline data. The legacy Float remains supported but is no longer in production. Both devices connect to the My Brewbrain platform for data visualization, brew history tracking, and third-party integrations with brewing software like Brewfather and Grainfather.

Products and services
- Float Pro Wi-Fi-enabled digital hydrometer and thermometer that automatically tracks fermentation activity, specific gravity (SG), and temperature in real time without opening the fermenter. Features offline data buffering of up to 170 days. Designed for home brewers and small craft brewers fermenting beer, cider, or wine.
- Float (legacy) Original digital hydrometer from Brewbrain that tracks fermentation parameters. Discontinued from production but remains supported with ongoing firmware updates and customer service.
- My Brewbrain Free online cloud platform for tracking brews with real-time and historical data, including CSV export capability, public brew sharing, and optional third-party integrations with Brewfather and Grainfather brewing management software.

Brewbrain partnerships and signals
Strategic signalPartnerships
Four partnerships are on record, tiered core and minor.
- Beer-o-MetercoreBrewbrain and Beer-o-Meter announced a partnership combining their smart brewing products. Both companies share a passion for products that help brewers better control their production process. The partnership aims to provide comprehensive process control solutions for brewers.
- BrewfathercoreFloat and Float Pro integrate with Brewfather, allowing device measurement data to be forwarded to Brewfather's brewing management software for comprehensive recipe and fermentation tracking.
- GrainfathercoreFloat and Float Pro integrate with Grainfather's all-in-one brewing system, enabling measurement data to be shared with Grainfather's platform for users with compatible setups.
- ØlbryggingminorBrewbrain held an online seminar with Ølbrygging (Scandinavian brewing supplier) as part of their expansion into Scandinavian markets.

Brewbrain competitors and assessment
Company assessmentOthers
- Brewfather: SaaS brewing recipe and batch management platform that integrates Float Pro telemetry into its brew logs. Functions as a data-layer partner rather than direct competitor but defines part of Brewbrain's ecosystem and switching-cost story.
- Grainfather: All-in-one connected electric brewing system from New Zealand with its own recipe/app platform that integrates Float Pro data. Ecosystem partner and indirect competitor at the prosumer end of the brewing stack.
Direct peers
- iSpindel: Open-source DIY wireless hydrometer built on a 3D-printed PET bottle housing with an inertial measurement unit, popular with tinkerer homebrewers. Competes for the same craft/homebrew fermentation-tracking budget as Float Pro, though from a community/DIY angle rather than commercial product.
- Plaato: Smart brewery monitoring hardware (hydrometer-plus pressure and flow sensors) with a cloud dashboard aimed at home and small craft brewers. Overlaps Brewbrain on wireless fermentation monitoring, integrated cloud platform, and craft brewer target segment.
- Tilt Hydrometer: The original and best-known wireless hydrometer for home and craft brewers, using a Bluetooth color/color-change sensor that tracks specific gravity and temperature inside the fermenter. Directly comparable to Brewbrain's Float Pro in product category, target customer, and decision criteria (price, accuracy, app ecosystem).
- Kegland (RAPT Pill): Australian homebrew equipment giant whose RAPT Pill is a wireless hydrometer pushing temperature and gravity data to the RAPT cloud portal. Closest head-to-head competitor to Float Pro given overlapping form factor, prosumer target, and integrated cloud dashboard.
Emerging players
- Inkbird: Broad IoT controller and sensor brand for fermentation (temperature controllers, Bluetooth thermometers, smart plugs) widely sold to home and craft brewers. Adjacent to Brewbrain on connected sensors for fermentation, but lacks a dedicated gravity/specific gravity instrument.
