About this item

  • Full Flavor Extraction: The Ratio Four Coffee Machine features a bloom cycle, also known as pre-infusion, that begins with a quick burst of hot water that causes the coffee grounds to expand in a “bloom.” After a 15-second rest to let the grounds settle, this matte black coffee maker delivers the remaining hot water, ensuring balanced extraction.
  • Flexible Brewing: Whether it’s a solo morning boost or a travel mug to go, these coffee makers have a 5-20 ounce capacity that adjusts effortlessly to your needs. Brew 1-2 cups with your coffee brewer machine or fill a big travel mug.
  • Consistent Temperature: These coffee maker machines have an advanced heating element that keeps water precisely between 91-95°C (195-203°F), meeting Specialty Coffee Association standards.
  • Easy Water Refills: Filling up these coffee machines for home is a breeze with the removable water canister that detaches for convenient refills right from the sink. You can even weigh the tank on a scale to reach the exact water volume you want, making precision brewing simple with this small coffee maker.
  • Compact Design: Standing at just 11.5” tall and 7.5” wide, this automatic coffee machine fits beautifully on any countertop. The clean, modern design of this compact coffee maker brings elegance to your kitchen while saving space.

    5.0 out of 5 stars A Coffee Maker for True Coffee Lovers
    Reviewed in the United States on January 18, 2025
    Verified Purchase
    I absolutely love this coffee maker! I’ve always wanted a way to brew just one or two mugs of coffee at a time, and this machine delivers. As a fan of pour-over and AeroPress, I was looking for a no-fuss method to achieve a similar quality. This coffee maker produces a consistent exceptional cup with the simplicity of pushing a button.

    I do have a couple of minor critiques. The start button is a bit too easy to press when removing or inserting the basket, but it’s something you adapt to quickly. Also, it feels like for the price there would be less plastic, but I guess plastic is pretty standard in most appliances these days. I also bought the expensive brand-name filters, but I will probably get the store-bought 8-12 cup flat basket ones from the store next.

    Overall, I’m very happy with my purchase!

    5.0 out of 5 stars Great single size coffee maker
    Reviewed in the United States on December 28, 2024
    Verified Purchase
    Bought this maker as a Christmas gift to my wife. Not going to lie, now I’m using it every morning because it makes such a good cup. I’ve been using an aero press with the pressure valve to make an Americano for my morning cup, the coffee brewed with the ratio has a clarity to it that I can’t explain. Just had to do a little dialing in to get the strength of brew I was after. Only critique is the crane for the filter basket isn’t included. I had to order one from ratio for $6 ($15 with shipping) one more thing, this maker can use the 8-12 cup melitta pleated paper filters. Still trying to figure out what mesh filters will fit.

    1.0 out of 5 stars Delivers coffee just warm, not good if you don't drink within the minute
    Reviewed in the United States on January 27, 2025
    Verified Purchase
    Makes good coffee but coffee doesn't stay hot enough more than 2 minutes, which is not enough time to enjoy a 2 cup. It ends up "just warm" within 2 minutes of pouring which is not pleasant to drink. If they upgrade the unit to keep the coffee hot/warm enough, long enough, I will buy again.

    2.0 out of 5 stars I wanted to like it, but...
    Reviewed in the United States on February 14, 2025
    Verified Purchase
    First, I really liked the taste of the coffee this machine produced. It's better than batch brewers I've had. Unfortunately as others have said, the brew temp isn't hot enough. If you're not pouring the coffee immediately after it's done, you're going to find yourself reheating it in the microwave. I found myself doing this constantly. And since there's no warming plate, if you're finishing the rest of the carafe 30-60 mins later, the coffee is cold. In addition, there's no drip stop so after the brewer says it's complete but still dripping, you can't easily pour a cup without having drips fall onto the base. Given these compromises, I can't justify paying this much. I would consider a Ratio in the future if they can address these issues.

    5.0 out of 5 stars Works great for my needs
    Reviewed in the United States on February 28, 2025
    This has worked really well for my needs. I only ever do a single cup of coffee in the morning, and this has been perfect. I usually fill the water container up to the 2 line, which produces about 10 oz of coffee. The complaints mentioned in the other reviews are legit, though. The coffee definitely doesn't stay super warm for very long. The button is finnicky because even a slight brush will turn on the machine (which is annoying since I have a hairless cat that can trigger the machine just by walking by) and it does drip after finishing (not an issue I had with my Ninja coffee machine). Still, I like it and will keep using it until it dies.

    1.0 out of 5 stars Not Ready for Prime Time - Returned
    Reviewed in the United States on January 10, 2025
    This new Ratio Four has a couple of major shortcomings which Ratio Customer Service readily acknowledged on the phone. The Ratio Four does not heat water to the same temperature as the Ratio Eight and Ratio Six per the Ratio Service representative. My unit produced only lukewarm, at best, coffee. The temperature (measured with a professional Thermapen) of the water at the Showerhead was 160F (instead of 195 - 203F expected) and the temperature of the coffee brewed into a cup using a V60 dripper was only 151F (instead of 175 - 180F expected). The Ratio Customer Service representative readily acknowledged that this is a known issue and suggested that I "pre-heat" the Ratio Four by running a full pot of water through the machine just prior to brewing my coffee. In addition, the water pump sometimes makes an unusual noise when beginning the Bloom cycle. The representative further acknowledged that the Ratio Four is their first brewer to utilize a water pump and they are also aware of this problem. He then told me that the Ratio Four is undergoing design changes to overcome these issues and a new version will be available mid 2025. I was then instructed on how to complete the Return Authorization form.
