Ratio Four Coffee Machine

I love the compact size of the Ratio Four. We have a Ration Six but save that for family gatherings. On a typical morning, the Four is perfect for my wife and me. I really like the glass carafe and the fact that the water tank is a separate unit. Both make it much easier to clean and maintain.

60 days of making a great cup of coffee with the Ratio Four. Water to the 3 line. 26oz of beans ground at 15 on a Baratza Encore, and using a Kalita Wave glass dripper with Kalita filters. Others have reviewed the On switch placement. I will simply say that you get used to it and it becomes a non-factor after a couple weeks. Pros Best tasting cup of coffee from an "automatic" machine I've been able to produce For me, the tempurature is perfectly drinkable the moment the cycle finishes Ease of switching to other drippers Water container - easy to fill, easy to place Cons Because I switched to a different dripper, the front of the machine (including the power switch) gets covered in steam/moisture - which is then wiped down daily... maybe this is a Pro because it means that I keep my machine clean daily.

The best coffee maker I have ever used. I got the ratio, and a moccamaster at the same .the moccamaster got sent back it was nowhere in the ratio 4s league.

It is the perfect cup of coffee. One problem is that the carafe doesn’t keep the coffee warm. So for me one cup at a time. Ok

SO in love with this machine, brews wonderfully!! I will say the one thing to get used to is proper use of the bare "button". It is very easy to mistakenly activate a brew cycle while removing the basket. The button is in the exact location that your thumb would naturally be for leverage of the basket removal. It's a small thing but hopefully a consideration for the next version. The form factor and overall size is wonderful and pairs very well next to my fellow grinder. I particularly enjoy that I can place the water reservoir right on top!

I think that the coffee made from the Ration Four is good but I had to buy a cup warmer to keep the remaining coffee in the carafe warm. I would suggest adding a warning element under the carafe so an extra item does not have to be purchased to keep the coffee warm while waiting to pour a second cup.

Awesome little machine. Really well-built. Brews consistently, quickly. Other reviewers have mentioned the placement of the brew button as an issue, but I don’t have a problem with it. Easy to clean, no fuss, no frills - just simple coffee-making. I pull espresso a couple of mornings each week with a Cafelat Robot. When I want that intentional, slow ritual, I go to the Robot. But most mornings, I’m unfortunately hurried and don’t have time for anything but grinding 35g, pouring water to the “4” mark, and hitting “brew.” The Ratio 4 is perfect.

The Ratio Four has almost completely replaced my manual pour over. It makes consistent, well extracted coffee over and over with one touch simplicity. I love the overall design of the machine as well as the footprint and flexibility on placing the water tank. From a design standpoint, the star of the show is the carafe. This is so well made & beautiful and the rubber base is exactly what any glass carafe needs. The lid is great too but I wish there was some kind of integrated storage for it when the coffee is brewing. That's probably my only complaint so far. Highly recommended!

This is a great machine and exceeds all my needs. The design of the unit is nice and it makes a phenomenal cup of coffee. I wish the water resevoir was glass - the plastic is fine but it just feels cheaper. The machine itself it well designed although I agree with other reviewers about the awkward placement of the button - as you remove and replace the basket you need to be aware and avoid hitting the button by mistake. Overall it's terrific, quick to make a great cup of coffee, easy to clean and maintain. Definitely pleased with my purchase.

I am loving the Ratio 4 for its beauty, simplicity, and excellent coffee.

The Coffee does taste very nice with this machine. The on button can cause the machine to start when you don't want it to because it's right where you put your hand when removing or inserting the filter basket. If you want 4 cups of coffee but only 2 at a time because a 4 cup mug is very large by the time you pour your second serving the coffee is cold because there is no warmer. We end up serving all four cups at once in a very large mug to work around that, seems to work but somewhat cumbersome. The unit is quite expensive for the features it offers. We are happy with it but feel it could have been more competitively priced and would have been nice if it was manufactured in the US as well instead of China.

I really like this new coffee maker so far. It's the perfect size for my wife and I, and I like that I can also use my Hario V60 to brew a single cup when I want. The removable water reservoir is a brilliant touch and gives us the flexibility we need to put the machine where we need, and also to use the precise amount of water to get repeatable results without guesswork. A couple of minor nits that prevent it from getting a full 5 stars: (1) The buttons on the top of the machine are very sensitive and are easy to press accidentally when inserting or removing the filter basket. I've had to adapt my technique to prevent this from happening. (2) The electrical plug is very loose where you insert it into the back of the machine. If the machine gets jostled or moved, it often becomes dislodged and the machine either won't start or stops brewing. (3) While the machine nominally makes 4 cups of coffee, it really makes about 2 mugs, or roughly 650 ml. of coffee. Normally, that's perfect, but occasionally, I'd like a little more. It's no big deal and coffee brews quickly enough to make another batch, but be forewarned. I got the kickstarter edition, so I don't know if subsequent production models are changed or have different features, but for the price, the Ratio Four is well worth it, despite the few minor issue mentioned above.

As an avid totally blind coffee drinker, I purchased a high end coffeemaker which, even for my best sighted buddy, was challenging to use without making a complete mess. After a Google search, I discovered the ratio Four. Knowing that a great cup of coffee starts with a clean pot and high temperature, the Ratio was the only option left for me. I was not disappointed because the coffee is not only the right temperature, but the flavor equals or surpasses any made by a coffeehouse barista. i know of no other coffeemaker that offers a 5 year warranty which also speaks to the high quality of this coffeemaker

Working well for me; I usually only make 12-16oz coffee for myself in the morning, so my options on machines are limitted for a push-button machine. Coffee is great. Machine seems solid. It looks really nice. Happy with it so far.

I’m obsessed with this little machine. It’s sleek and optimal for my counter space and flavor profiles!

I love this machine. It’s the perfect size and makes an amazing cup of coffee. I have been using it with an origami dripper and it’s a workhorse. A++

I love how easy it is! It creates a great flavored coffee with less work than a normal pour over. I’d recommend the ratio 4 for any coffee lover, that wants a little easier, pour over system and only needs to make coffee for one to two people.

Beautiful, silent, elegant and perfect coffee taste.

The machine prepares a decent cup of coffee, but not up to the standard set by the Ratio 8.

The perfect size. The perfect cup. Ratio does it again!
