Ratio Coffee 5 star review on 18th November 2025

“I have had the 6 for less than a week, still tinkering with it. It looks fantastic. Extremely quick brew. Dislikes include the spritz of coffee from the gasket upon pulling the carafe after the brew is complete, also finding coffee still in the basket after the brew is supposedly complete (maybe my fav Starbucks preground is too fine?) The water filler cap should have some exterior marking on it to alleviate turning it upside down to fit it in correctly. The carafe really needs to be inverted quite a lot to finish out the last of the coffee. Positives: The coffee we have been drinking for years has taken on a totally different wonderful flavor. Overall I like it, but may have to make some adjustments to accommodate the 6”

“Overall it's great, but it's I hate the fact that you can't seal off the carafe now. I tend to make a pot and drink it throughout the day alone. Cutting another groove in the lid would have been simple to give it a third locked shut position. The simplicity with which that would have been accomplished through no real additional extra manufacturing costs and the fact y'all choose not to because "we didn't see any added benefit" kind of ruins any good about the new design, even though other than no shut position its pretty perfect.”

Thanks for the note! We actually produced multiple prototypes of a 3-position design, but after months of testing, we decided the 2-position was better. Appreciate your input!

“4 out of 5. It's beautiful,it maintains heat but needs some sort of handle. It's hot to pick up and easy to drop. This is our second.”

“Immediately after attempting to clean my Ratio 8 with Halefresh, the coffee maker stopped working. I have sent it to Portland to get fixed.”

“After a few months with 6/7 days/week of use, the coffee is consistently outstanding. I have but one critique, the lid of the carafe. For maintaining temperature, it’s great. It sucks for pouring. I’ve read the “how to” instructions. It also leaks when pouring is finished. Coffee and water get into the lid itself as well. The inside rim design of the carafe probably contributes to the pouring issues too. Perhaps a cutout or beveled inside rim of the carafe where it meets the spout could be explored. Respectfully, with the top notch materials and machine design contributing to the cost, a better lid/ pouring system needs to be addressed. Thanks for your attention, Dan”

“Pros: makes a great cup of coffee, looks great, I enjoy the daily coffee process, customer service has been excellent Cons: lead time was absurd and way longer than expected, carafe lead time was even more absurd, annoying that all of it arrived in boxes from china, pouring out of the thermal lid is always a mess. Instead of being able to grab the pot and top off cups in the living room I have to gather cups and pour over the sink because it always makes a mess”

“The Six makes great coffee, but there is inconsistency of the volume markings on the reservoir and the documentation.”

“Great coffee! Ratio Six feels like a great quality build and i love the bloom feature! Only thing i’d like to point out is the power cord connector that sticks into the machine itself comes loose alot. I tried reaching out, but still did not get a response for a replacement.”

“The loaner is great. It arrived clean and ready to use. I am thankful for the loaner program, because I can still brew coffee in a nice, elegant coffee maker. Thanks Ratio.”

“It's a good quality machine. The extraction isn't as good as a pourover with a gooseneck and a kalita. My guess is that it's because the water passes thru the grounds too fast for a good extraction. But, it does produce coffe in 5 minutes, so I will continue to use it on most days. Overall I'm very happy with it.”

“I like the opening of the carafe on the ratio 6 for easier cleaning. The carafe on the ratio 6 keeps coffee hotter much longer than the ratio 8.”

“I would rate it a 4.5. I love it and everything about is great, the look, the cup it produces, it's wonderful. The only thing I have against it is its a little messy to pour. Intuitively I want to push the lever down and then pour but when I do that it makes a mess. I know you guys say to pour then push the lever but it still makes a mess, other than that fantastic product!”

“Pros: Very beautiful and sleek design, great brewing temperature and holding the temperature thought the brewing process. The coffee is excellent, and that is the most important thing. Cons: The h2o level markings on the water container are very inaccurate, and at the price of the Ratio, I expected that to be way better. The lid to the thermos looks nice but feels cheap and doesn’t pour very smoothly. Overall a solid coffee maker, but again at the price it is, would like to see those two things improved on.”
