  • Glass Carafe is an Add-On

Ratio has two awesome coffee machines: Ratio Eight and it's little brother, Ratio Six. Both machines are:

  • beautifully designed

  • brew up to 8 cups of coffee at one time

  • made using a combination of handblown and BPA-free glass

So which coffee maker is right for me?

Alright, I'm going to quickly break down what I love about these machines and help you decide which piece to add to your kitchen counter or favorite coffee corner at home.

The two coffee makers have some obvious differences but let's start with the similarities.

Size: Roughly the same. Ratio 8 is slightly taller.

Weight: Ratio Eight is 6 lbs heavier, coming in at 14lbs (due to its precision die-cast aluminum construction).

Colors: Both come in 3 colors, and they all look like art.

Brew Size: Both machines can make up to eight 5oz cups per brew.

Makes the perfect pour over every time

The real secret sauce in every Ratio coffee maker is its ability to make the perfect pour over coffee every time.

Once you have your ground coffee & water loaded into the Ratio, all you need to do is press one button.

One Button, 3 cycles: Bloom, Brew, & Ready

The Bloom cycle is essential to all Ratio coffee machines because it is key to brewing smooth, bitter-free coffee. This feature slowly soaks the grounds via the Ratio-exclusive stainless steel spiral shower head.

The grounds are then left to breathe for about 45 seconds before moving on to the brew cycle.

Brew time and temperature for both coffee machines is the same. The water heats up to 200 degrees with the die-cast aluminum heating element… and the whole brewing process only takes about 8 minutes from start to finish.

The simulated pour over technology leaves you with delicious and flavorful coffee every time.

Hot coffee can be enjoyed now or later

Even though both Ratio coffee machines brew smooth and quality-tasting coffee, they give you two different experiences.

The Ratio Eight has a handblown borosilicate glass carafe lets you experience your coffee from Bloom to Ready. You can smell, see, & hear your coffee as it's being made. Plus, it's open filter design makes it ready to drink instantly.

With the Ratio Eight, you're meant to enjoy the coffee soon after it is made.

This model is great for anyone looking for a fresh pour over before they head to work in the morning, or for anyone who wants a more delicate touch when it comes to how their coffee is prepared.

This coffee feels and tastes like it was brewed by a human.

The Ratio Six keeps your coffee warm all day.

It has a flat bottom filter with a heat shield and a double-wall stainless steel thermal carafe.

Although it doesn't have the same manual pour over vibe, the Ratio Six keeps your coffee extra toasty while it's brewing… and while it's sitting. It's more of a commercial brewer, while still delivering a delicious and easy pour over.

The Ratio Six a good choice for anyone who drinks multiple cups a day, or for busy people who constantly need a hot top-up.

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.
