Brezi Automatic Cold Brew Coffee Machine Review

Can You Really Make Great Cold Brew in 15 Minutes?

Cold brew has always been about patience. Traditionally, you grind coarse, steep for 12–24 hours, and hope the result is worth the wait. The Brezi Cold Brew Coffee Machine promises something very different: fresh cold brew in around 15 minutes, with temperature control, blooming phases, and repeatable recipes.

That’s a bold claim considering cold brew coffee normally takes 12-24hours! So we put it to the test.

This review is based on a real-world brew, filmed start-to-finish, using a light roast specialty coffee and no prior “dialling in”. What follows is an honest breakdown of the Brezi experience: build quality, brewing logic, flavour results and whether it actually makes sense for home users.

First Impressions & Unboxing

Straight out of the box, the Brezi machine is smaller and more compact than expected, in a good way. It doesn’t dominate the bench, and the footprint feels deliberate rather than bulky.

The glassware deserves a mention however these are sold seperatley. Both servers feel premium, well-weighted, and thoughtfully designed. While the branding suggests “cold brew only”, the double-walled construction implies they should handle heat, though we’d still recommend checking Brezi’s official guidance before using them for hot coffee.

Design & Interface: Surprisingly Thoughtful

One of the biggest surprises was the customisable magnetic nameplate on the front of the machine. Ours arrived with a Basic Barista plate engraved, a small detail, but one that signals real attention to branding and presentation.

The interface on the Brezi machine combines:

• A rear selection dial (used to choose roast level and modes)
• A clear LED display
• Physical buttons embedded into the front panel (not a touchscreen)

This hybrid approach works well. It feels more durable than touch-only machines and avoids the “fingerprint-covered tablet” problem that plagues many modern brewers.

Brewing Logic: Not Just Cold Brew

Brezi isn’t simply forcing cold water through coffee quickly. Instead, it uses a controlled brewing process that includes:

• A heated bloom phase (around 65°C)
• A controlled flow rate
• A cooling phase before the main extraction
• Precise temperature and timing control throughout the brew

This is important: the machine is clearly designed around extraction theory, not just speed.

During our brew, the machine:

• Suggested 16g of coffee (we used 15g)
• Brewed roughly a single-serve cup
• Took just under 15 minutes from start to finish

We intentionally estimated grind size rather than following a strict recipe, using 40 clicks on a Comandante C60 (medium-coarse, sand-like consistency). This gave us a good baseline for evaluating how forgiving the machine actually is.

Filter Basket & Flow Characteristics

The magnetic clip-in dripper uses a flat-bottom 155 filter, with a base design that sits somewhere between an Orea-style fast brewer and a traditional flat-bottom dripper.

A few key observations:

• Flow rate is moderate-to-fast
• There’s enough resistance to allow proper extraction
• The basket could easily be used as a standalone pour-over dripper

This flexibility adds value, especially for users who like experimenting beyond a single brew method.

Brewing Experience: Clean, Controlled, Minimal Mess

One thing Brezi gets very right is cleanliness.

Throughout the brew:

• Minimal splashing
• No errant drips
• No overflow or mess around the basket

The base acts purely as a drip tray, it doesn’t lock the server in place. This is worth noting, as you’ll want to be careful when removing the server mid-brew.

That said, this design also enables something interesting: brew progression tasting. Because the server isn’t fixed, you can swap vessels during brewing to taste different extraction stages, a genuinely useful feature for advanced users.

Taste Test: The Most Important Part

This is where the Brezi really surprised us.

Using a light roast, washed Colombian coffee, brewed on the very first attempt, the result was:

• Light in appearance (as expected for cold brew)
• Surprisingly full-bodied
• Low bitterness
• Retained more acidity than most cold brews
• Clear sweetness and origin character

Importantly, this didn’t taste like “watered-down filter coffee”. It tasted like proper cold brew, but with more clarity and structure than many long-steep methods.

Was it identical to a fresh pour-over? No and it shouldn’t be. But it retained far more of the coffee’s personality than expected, especially given the short brew time and experimental grind size.

Temperature & Concentrate Mode

The finished brew was cool, but not ice-cold, which is reasonable given:

• A ~30°C ambient room temperature
• The machine prioritising extraction over chilling

This is where concentrate mode becomes important. Brezi allows you to brew a stronger concentrate, designed to be diluted with ice, milk, or water while maintaining balance.

For iced drinks, milk-based cold brews, or creative recipes, this mode makes far more sense than trying to force the machine to brew ice-cold liquid directly.

Who Is the Brezi For?

The Brezi Cold Brew Machine makes the most sense for:

• People who love cold brew but hate waiting 12–24 hours
• Coffee drinkers who want repeatable, adjustable recipes
• Users who enjoy experimenting with temperature, bloom, and flow
• Homes where cold brew is a daily ritual, not an occasional treat

If you’re someone who’s happy with jar-and-fridge cold brew once a week, this machine may feel excessive. But if cold brew is part of your daily routine, especially in warmer climates, Brezi offers something genuinely different.

Final Thoughts: Is It Worth It?

What impressed us most wasn’t just the speed, it was how thoughtfully the machine approaches extraction.

Brezi doesn’t try to shortcut coffee science. Instead, it adapts it to a faster, controlled workflow that still respects flavour development.

On our very first brew, with no prior tuning, the results were shockingly good.

That alone says a lot. Watch the full YouTube video unboxing, brewing and tasting with our first impressions of this machine live on camera!
