I am an avid coffee drinker. Like, at least 5 cups a day. And I consider myself well-versed in excellent java. My husband playfully calls me our family's coffee connoisseur because I'm super particular about the way my brew tastes.

I rarely make coffee at home because I just can't get it to taste right… so I end up tossing it and buying a cup of pour-over from a local shop instead.

Recently, a co-worker of mine introduced me to Ratio: an at-home pour-over coffee brewing machine. She said:

  • it has 3 brewing cycles, but you only have to press 1 button
  • it looks nice in her kitchen
  • the coffee always tastes really good

All these things ticked my boxes and I wanted to see if it lived up to the hype… so I bought myself a Ratio coffee maker.

After using Ratio for 6 months… let me tell you why I love it.

But first… let's address the elephant in the room…

When I was researching which machine to buy, I noticed the cost. Ratio is not cheap, but neither are its premium materials.

I realized that I'm not just getting any regular coffee brewer. The Ratio Eight is a luxury coffee machine that's designed to sit on my kitchen counter and look like art while giving me fresh coffee flavors and a relaxing, time-saving coffee experience.

Ratio coffee machines are not like the ones you get from Target.

It isn't made from plastic and thin glass like the coffee machines you can get at a retail store.

It has a precision die-cast aluminum body with hardwood details. The one I chose comes with a beautiful handblown borocilicate glass carafe.

No stone is left unturned!

It even has a unique stainless steel spiral shower head that soaks coffee grounds in two different intervals, giving you the smoothest flavors and perfect pour over in under 10 minutes… so I never have to sacrifice quality because I don't have time!

Unboxing the Ratio was easier than I thought

First of all, unboxing the Ratio coffee maker was super easy. I just pull it right out of the box, did a once-over with the included wash and microfibre cloth… and it was ready to go.

It came with a user manual that I didn't read… the brewer only has one button.

Plus, the Ratio website has more than enough information to help you get started.

My first impression

I was impressed by how minimalist the Ratio Eight looked. Even though it can make up to 40 ounces of coffee, the glass carafe and precision die-cast aluminum base looked sleek and pretty in my kitchen.

It makes an excellent pour over… and there's aways enough for a second or third cup

So Ratio uses something called a smart brewing algorithm that was designed to get rid of bitter flavors and make a smoother-tasting brew.

It actually does this through 3 automatic cycles.

Cycle 1: Bloom — Extracts coffee flavors & gets rid of bitter tastes

When you first turn this coffee machine on, it triggers the Bloom cycle. This setting heats the water to around 200 degrees.

Fun fact: This is apparently the temperature where most people enjoy drinking their coffee.

When the water is heated, some of it gets sent through a stainless steel spiral shower head to saturate the all of the grounds evenly.

After letting them breathe for about 30 seconds, the rest of the water is sent through. This is how Ratio extracts delicious flavors from each bean without getting any bitterness.

I've been sipping on Ratio's Ethiopia Geta Bora blend because it has just a touch of honey and peach flavors. The Ratio Eight brings out all of the sweet and floral tastes that I like, while balancing its slightly stronger acidicity… *chef's kiss*.

Cycle 2: Brew — Delivers a pour over that tastes barista-made

After less than 10 minutes in the Brew cycle, you're left with the perfect pour over. And I'll admit… it even brings out notes of flavors in my grocery store coffee grounds that I never noticed before.

The glass carafe's open filter design lets you fully experience your coffee.

I've been using Ratio's recycleable cone-shaped paper filters, but they aslo have a reusable stainless steel filter too.

With the open design, I can smell the rich flavors of the coffee filling my kitchen… hear the soft bubbling of the brew… and even see dark java as makes its way down the carafe one drip at a time.

It's actually pretty therapeutic… like watching an hourglass filled with coffee.

And if I don't have time to watch in the morning, I press the button and it's brewed in under 10 minutes… before I'm even finished getting myself ready.

Cycle 3: Ready — Enjoy a fresh 200-degree pour over!

Every brew is ready when:

  • the coffee is a steamy 200 degrees

  • the bitterness is reduced

  • the flavors are carefully extracted from every bean

When the Ready cycle is lit up, you finally get to enjoy a pour over that's smoothe, delicious, and feels human-made.

This isn't the kind of coffee machine you hide in the cupboard… This thing is decor

I got the Ratio Eight, because it came with a hand-blown glass carafe, which I thought looked really cool… and I was right.

The carafe is like a cool pitcher… but for coffee.

When I serve coffee to guests, the glass carafe looks nice on a tray… and the silicone heat lid looks like its floating inside.

The machine's body is made from precision die-cast aluminum and it has stunning hardwood details.

This coffee machine comes in three different colors, but I got the bright silver version so that it would match my stainless steel kitchen.

A quick comparison

There are three different Ratio coffee machines to choose from, so you can pick what works for you.

I got the Ratio Eight that comes with a glass carafe. The Ratio Eight Thermal Set is basically the same, except it comes with a double-walled stainless steel thermal carafe to keep your brew warm for longer.

The Ratio Six is more affordable and slightly smaller compared to the Ratio Eight, but the Ratio Eight is made in the USA… and is way prettier.

After using Ratio for 6 months, I can confidently say… it lives up to the hype.

All Ratio coffee machines have a 30-day guarantee and a 5-year warranty, so you're not married to your choice.

You get:

  • the precision of a high-end coffee machine
  • the construction of a commercial coffee machine
  • the aesthetics of modern kitchen decor
  • the taste of a fresh barista-made pour over
  • a 30-day guarantee & 5-year warranty

By far the best coffee machine I've ever used. Ratio's customer service and attentiveness to the needs of the customer are second to none. They stand behind their product and will do everything they can to make sure their product is in top working order.
