Sintered 304 stainless steel stone — durable, clog-resistant, and easy to clean.
120mm length provides more surface area for faster carbonation and finer control.
0.5 micron porosity ensures optimal bubble size for rapid CO₂ absorption.
1.5″ tri-clamp base offers a sanitary, secure connection on any compatible port.
Ball lock gas-in poppet allows fast, reliable connection with a keg-style disconnect.
Disassemblable design makes cleaning and sanitation simple.
Ideal for Unitanks, brite tanks, and any pressure-capable fermenter.

Designed to Pair Perfectly with the Bräu Supply Unitank

This stone fits directly onto the dedicated carbonation port of your Bräu Supply Unitank. Just sanitize, connect, and dial in your pressure — it’s the fastest, cleanest way to force-carbonate your beer.

Usage Guidelines

Sanitize thoroughly before use.
Install via 1.5″ tri-clamp port with the stone fully submerged.
Connect CO₂ via ball lock disconnect.
Regulate pressure according to your target carbonation (do not exceed 15 PSI on Unitanks).
Allow 12–48 hours for carbonation depending on temperature and CO₂ level.

Technical Details

Using the Carbonation Stone Accessory with Your Unitank

Max Working Pressure: 15 PSI

Overview

This external carbonation stone accessory connects to your Unitank via a standard keg-style gas-in poppet (ball lock or pin lock). It allows you to carbonate beer directly in the tank using regulated CO₂ pressure.

Important Safety Notes

  • Do not exceed 15 PSI, the maximum working pressure of your Unitank.
  • Ensure the carbonation stone is fully submerged in beer before applying gas.
  • Sanitize the stone and fittings before each use.

What You’ll Need

  • CO₂ tank with dual-gauge regulator
  • Sanitized gas line with keg-style gas disconnect
  • Carbonation stone accessory with gas-in poppet
  • Star San or equivalent sanitizer
  • Cold beer in Unitank (0–4°C / 32–39°F recommended)

Step-by-Step Instructions

1. Sanitize the Stone

  • Soak the carbonation stone and poppet in sanitizer for 10–15 minutes.
  • (Optional) Connect your gas line and briefly push CO₂ through the stone outside the tank to purge sanitizer and check flow.

2. Install in Unitank

  • Insert the carbonation stone through a suitable port or valve on the Unitank.
  • Ensure it is securely mounted and fully submerged in beer.

3. Connect Gas

  • Attach the sanitized gas disconnect to the carbonation stone’s poppet.
  • Ensure the connection is secure and leak-free.

4. Apply CO₂

  • Set your CO₂ regulator between 5–15 PSI.
  • Start at 5–8 PSI for slower, more controlled carbonation.
  • Allow gas to flow continuously through the stone.

5. Monitor Carbonation

  • Carbonation typically takes 12–48 hours, depending on temperature and target CO₂ volumes.
  • Use a carbonation chart and sample from the racking port to check progress.

Tips

  • Carbonate at colder temperatures (0–4°C) for better CO₂ absorption.
  • Low pressure over longer periods yields more consistent results.
  • Always keep the stone submerged while gas is flowing.

After Use

  • Disconnect gas and remove the stone.
  • Soak in hot PBW or similar cleaner.
  • Rinse thoroughly and sanitize before storing.
  • Store dry or submerged in sanitizer solution.

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.
