“I left a voice message and have not received a call back. My Carafe is leaking when we go to pour and would like a replacement sent out and I will send the defective one back”

“The coffee tastes horrible. I have tried every combination of grind, etc. I have used pour over makers before as well as French press. This one is the worst. Coffee is weak and under-flavored. No amount of changing the grind or adding extra coffee works. Not worth the $$ at all. Especially after waiting months to receive it.”

Hey Toni! We're here to help! The first thing to check is your paper filters - are you using Melitta? We would like to send you some of our filters which we believe lead to better tasting coffee. Also would love to know how much coffee you're using and what kind of grinder. We think we can get you into some great tasting coffee with some small tweaks, but if not we have a 30 day "love it" guarantee. Please email us and we'll get you some filters at no charge! hello@ratiocoffee.com

“I was excited to finally receive the Ratio 4 after a long wait but unfortunately it was a major disappointment. The machine has a high pitch tone when it starts brewing. The placement of the power button is annoying and constantly is accidentally touched and activated when you remove or put back the basket. Lastly, when I put in my cream the coffee was too cold which when I normally do a pour over at 204 it’s perfect with cream. So it brews too cool. Also, customer service has been totally non responsive! I will be returning this machine if they ever will acknowledge my email.”

“Hi Mark, how are you? Thank you for my R4 unit. From my initial 2x brews, I the R4 makes a decent cup of coffee (6 out of 10 rating). I noticed the water spouts are not consistent and pours uneven both times so far. I’m hoping It works better the next couple brews and will take of video. Cheers, TimWYoung”

“The coffee is good though no where near as consistent as my Balmuda.inconsistency seems to be the weak spot with many coffee makers. I roast my own beans, weigh them out, grind immediately before brewing and measure out the water. Was hoping to find a maker that could make multiple cups and have the quality and consistency of the Balmuda.”

“The materials and feel of the R8 at 5 star! But, the thermal carafe does not do a good job at keeping coffee warm and it drips when you pour. Very annoying. Also, way too much water comes out for the bloom. I wish that could be controlled”

“Honestly, Trey was amazing. I do not feel like I'm exaggerating when I say that his might be the best customer service experience I've had in a long time.”

“The material is excellent and they perform well. They would be easier to use if there were more pleats, which likely would translate to smaller pleats. This smaller pleated shape would probably keep the filters up against the wall of the basket more consistently than filters with larger pleats.”

“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”

“This review is for the Ratio 4. The wait is finally over and well worth it! I saw the demo at the SCA in Portland and was chopping at the bit to get one. The size is perfect. My first cup was outstanding, very smooth and balanced. I used a bright Kenya, and I was able to taste some fruit notes and plenty of clarity. I did a side-by-side comparison with the Fellow Aiden, and I found the Ratio 4 to be the better-tasting cup. I prefer not to deal with settings. I highly recommend this brewer. You get the benefit of a pour-over without the hassle of timing, and it has the built-in bloom feature. It does it all for you. I can now retire my Ratio 6 since it is larger than my needs.”
