Ratio Coffee 5 star review on 18th November 2025

“I couldn’t be happier with the Ratio Six, it makes excellent coffee. It’s easy to clean, easy to use, but really delivers some high quality coffee. One thing I would like are some more carafe options, and eventually more colors.”

“Like the product very much. Only issue has been the reusable filter. I don’t think it releases the filtered coffee fast enough. Seems to be significant back up of coffee resting in the filter as it slowly sifts thru the stainless filter delaying the first cup of coffee prep time. I have since shifted back to paper and will likely stay with that for foreseeable future. If you are willing to credit me for the filter I would certainly take it and be willing to ship the item back. Again, unless you have a better solution I’m going to stick with paper filters. Hope this make sense. Thanks Eric”

“The Ratio company told me they are refining the Six’s carafe lid material and functionality, and recalibrating its tank’s measurements. With that said, this machine makes superior tasting, highly expressive coffee even compared to hand pouring— probably due to its heat shield. I highly recommend this beautiful SCA certified home brewer despite the minor imperfections. Buy it for $339 since the refined version will likely sell for more. I’m a Portland foodie who roasts his own coffee beans, so if you’re anything like me, you’ll love the Ratio Six.”

“The best coffee maker on the market. I spent a lot of time researching and my experience completely exceeds the the expectations I had for the Ratio Six. Additionally, there were delivery issues and the team quickly resolved it. A great coffee maker and great customer service- thank you team Ratio!”

“First cord was loose fitting and fell out easily. The replacement cord fits snugly and no interruption of service. Very impressed with how promptly the problem was resolved, thank you Ratio for the excellent customer service.”

“As someone that did V60 pour over for years, it makes some fantastic coffee. My only constructive feedback is: 1. When brewing finishes and you pull the carafe out, the rubber lip at the top likes to flick hot water at you. 2. The pour on the carafe when the lid is on could be a lot better. It doesn’t come out very smoothly and tends to splatter. Other than that, we love ours! These are minor issues so it’s still 5/5 for me.”

“I enjoy and love the coffee it makes! I am a bit sad I can not use my Chemex 8 cup or any chemex carafe but I'm good with the coffee maker and it's incredible Brew from 2-8 cups. I'm still figuring out if flat bottom, cone or Chemex filters make the better brew so as time goes I use the Ratio 6, Cafe Speciality and Chemex to brew coffee each day depending on schedule. I finally have a wonderful coffee system and with fresh ground beans it's always a win win! Thanks Ratio for making an easy coffee maker to use especially early in the morning when I'm not fully brain functioning!”
