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.

The Bonavita is a simple, compact machine (about 12 inches x 12 inches) for only $190, and it makes coffee that ranked in the top three in our taste test. Its philosophy seems to be “everything you absolutely need, nothing you don’t.” That means it’s SCAA-certified for water temperature and brew times, boasts pre-infusion capabilities, and has a flat-bottom filter basket that extracts grounds evenly. That’s it.
“So simple and easy to use. I’ve had the older version for ten years, tested out and researched so many to try something different only to return to this one, and I have no regrets. I LOVE IT! Most coffee makers put out a lot of steam at the top, which is unfortunate when stored under a cabinet. This has zero steam on top of the coffee maker. Also, most water reservoirs have a lid that flips open, which is also inconvenient when stored under a cabinet. This lid slides side to side, and brews a whole pot of coffee in about three minutes. Very convenient for busy, on-the-go, impatient people like me.”
It’s obvious, but easy to forget: If you don’t clean out your coffee machine’s carafe after each use with soap and water, you’ll always end up tasting a little bit of yesterday’s now-bitter brew. Thermal carafes need to be hand-washed, but all the plastic components of our top picks — brew baskets, lids, etc. — are dishwasher-safe if you keep them on the top rack.
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.
