This testing was designed to highlight the difference in how each machine extracted its coffee grounds. Remember, extraction is tied to water temperature, how long the grounds had to steep, and how evenly that water is distributed in the brew basket. (Depending on how the machine distributes the water and the shape of the basket, any particular ground may or may not receive the same amount of time in contact with water — thus any individual grind may be over-extracted, under-extracted, or just right.) Properly extracted grounds would have a balance of notes and aromas, from slight hints of acid to a pleasant amount of bitterness.
Drip-style coffee makers already have a bit of a flavor handicap when compared with other brewing methods, like pour-over and French press, which give coffee drinkers ultimate control over every aspect of the brewing (and therefore extraction) process. This makes it even more important to select a high-quality coffee bean for your at-home drip coffee maker. To learn more, we spoke with Saadat Awan at Woodcat Coffee in Los Angeles.

Whole bean coffee that you grind yourself is preferable to pre-ground, too. The bean’s exterior traps and protects all of the delicate, volatile, and water-soluble oils that give coffee its flavor. As soon as you break the protective shell, it’s easy for the flavor to get contaminated, and much of the aroma escapes as soon as the oils are exposed to air.

Our brew-performance tests measure the brew temperature and contact time (how long water stays within a sweet spot of 195° to 205° F for brewing). We measure concentration using a refractometer, a device that measures the amount of coffee dissolved in each brew. Our convenience tests look at how easy it is to set timers, fill the reservoir, clean the machine, and more. And for the first time, we’re incorporating predicted reliability and owner satisfaction ratings into the new Overall Score for each model. We determine these ratings for each drip coffee maker brand using survey data collected from thousands of CR members.
