If you're considering spoiling yourself with automatic pour-over coffee machines, you may be wondering which to choose between Chemex Ottomatic vs. Ratio Eight.

The manual pour over method takes time

Pour-over fanatics like me love the bright and flavorful cups of coffee that you get from this brewing method. However, brewing coffee with a manual pour-over method takes time and also technique. My busy schedule, for one, doesn’t always allow me to make pour-over coffee in my Chemex.

This is why I invested in a Chemex Ottomatic, and since then, I have not looked back. Recently, my friend told me about the Ratio Eight, which has inspired me to check out this coffee maker. Although it's pricey, the Ratio Eight offers good value for money and delicious pour-over coffee brewed with a distinct bloom phase.

The Chemex Ottomatic, on the other hand, can be used with different-sized Chemex carafes, making it a bit more of a versatile coffee maker. To find out where you stand in the Chemex Ottomatic vs. Ratio Eight debate, read on.

A Short Overview Of Chemex Ottomatic Vs. Ratio Eight

The Chemex needs no introduction among pour-over enthusiasts. The coffee maker is well-known and admired for its beautiful design. However, Chemex also has a reputation for requiring a bit of technique if you want to brew a decent cup of coffee.

This is where the Chemex Ottomatic comes in. You can now enjoy the same clear and nuanced coffee brews you normally get from a Chemex at the touch of a button. The coffee maker can accommodate a 3-, 6-, or 8-cup Chemex Classic or Glass Handle series.

The Ratio Eight is also an automatic pour over that boasts an elegant design. As opposed to the Chemex, Ratio Eight offers three distinct phases in the brewing process: Bloom, Brew, and Ready. This coffee maker is made from aluminum, borosilicate glass, and wood and is very expensive.

What Are The Similarities Between The Chemex Ottomatic And Ratio Eight?

The carafes of both the Chemex Ottomatic and Ratio eight are constructed from borosilicate glass, which is very durable and heat resistant. Both coffee makers also come with lids and a bottle of cleaning fluid. They also both work with Chemex paper filters and produce coffee that is smooth and flavorful.

It is difficult to tell the brews apart. You can also make iced beverages with both coffee makers.
