FOUNDER STORY
Hi, I’m Steven, founder and CEO of Bräu Supply.
Like many of you, I started brewing because I was obsessed with crafting beer that wasn’t just good—but exceptional. What I quickly realized was that most homebrewing systems were either too clunky, too limiting, or simply couldn’t deliver the kind of precision I was after. So, I set out to solve that.
My mission was simple - Build the most advanced, fully customizable brewing system for serious homebrewers.
Something reliable, compact, built to last for decades—and most importantly, capable of producing ridiculously delicious, consistent, high-quality beer every single time.
That mission led to years of prototyping, testing dozens of materials and configurations, and working with a growing community of brewers. The result? Unibräu—our flagship all-in-one brewing system.
Launched from our 2017 Kickstarter campaign, Unibräu became the world’s first countertop electric brewing system, designed for both beginners and seasoned brewers. Whether you're brewing from your kitchen, garage, basement, or backyard, it fits seamlessly into your life while delivering commercial-grade results.
With Unibräu, everything just clicks—from heating to chilling, every step is streamlined into an intuitive six-step process. You’re in full control, from grain to glass.
In 2023, The Spruce voted Unibräu the Best Electric Homebrewing System, and honestly, I couldn’t agree more.
Whether you're just getting started or you're already deep into your brewing journey, I promise you this:
Once you brew with Unibräu, there’s no going back.
It’s not just a brewing system. It’s the ultimate brewing experience—start to finish.
