  • 30’ coil-in-coil stainless steel construction
  • 1/2" ID inner coil (wort path), 3/4" ID outer coil (coolant path)
  • 1.5" tri-clamp wort ports for sanitary connections
  • Quick-disconnect water hose kit with stainless QDs included
  • Requires a wort pump for operation (not included)

Configurations

  • With Water Connection Kit – Includes chiller and QD water hose kit
  • With Water Connection Kit + Essentials Kit – Adds a 1.5" thermowell, tri-clamp tee, clamps, and gaskets for inline temperature monitoring

Technical Details

Overview

The Bräu Supply stainless steel counterflow chiller is designed for fast, efficient, and sanitary wort cooling during knockout. Built with a 30’ coil-in-coil configuration, it delivers performance comparable to a plate chiller while offering easier cleaning and less risk of clogging.

The wort side features 1.5″ tri-clamp fittings for secure, sanitary integration with your brew system. The water sideincludes ½″ 304 stainless steel quick disconnect (QD) fittings with silicone seals for fast, tool-free hose connection. Each unit includes a complete water connection kit with reinforced hoses, a ¾″ garden hose adapter, and a sink faucet adapter.

⚙️ Installation

  1. Connect the wort inlet and outlet to your brew kettle and fermenter using 1.5″ tri-clamp fittings.
  2. Attach the included braided hoses to the QD water ports.
  3. Connect the hoses to your cold water source using either the ¾″ garden hose adapter or the sink adapter.
  4. Orient the chiller so that wort and water flow in opposite directions for optimal heat exchange.

💡Flow Direction:• Cold water in → bottom QD port• Warm water out → top QD port• Hot wort in → top tri-clamp port• Chilled wort out → bottom tri-clamp port


⚠️ A wort pump is recommended for consistent flow and optimal chilling, though gravity feed is possible with proper elevation and control.

❄️ Operation

  1. Begin cold water flow first to pre-fill the outer coil and prevent thermal shock.
  2. Once water is flowing, pump or gravity-feed hot wort through the chiller.
  3. Adjust water flow as needed to control wort outlet temperature.
  4. Transfer chilled wort directly to your fermenter.

🧼 Sanitizing & Cleaning


Hot Wort Sanitization

This chiller can be effectively sanitized by running hot wort through it during the final 5–10 minutes of the boil. This method eliminates the need for chemical sanitizers and ensures the wort path is sanitized immediately before knockout.


✅ This is the preferred method for fast, chemical-free sanitization.


Post-Use Cleaning

  • Flush both wort and water circuits with hot water immediately after use.
  • For deeper cleaning, circulate brewery-safe cleaner (e.g., PBW) through the wort side.
  • Rinse thoroughly and allow to air dry.
  • Disconnect hoses and store dry to protect seals.
  • Inspect silicone QD seals and tri-clamp gaskets regularly.

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.
