These organizations consider how long it takes you to brew the coffee, the social impact of the coffee maker, as well as the roasting ability of the coffee maker. The best coffee maker will be BPA free and certified. An SCAA certified coffee maker, for example, will be able to deliver water at optimum temperatures throughout the whole brewing process, without compromising the integrity of the coffee at any point.
It’s not that cone filters won’t make a great cup of coffee — the OXO On 9-Cup still ranked fifth out of 10 in our taste test. But flat bottoms generally allow for the grounds to be more evenly extracted and increase the coffee’s flavor. (It’s no coincidence our other three recommendations have flat-bottom brew baskets). You may have to do a little more tweaking to get this coffee maker’s brew to the best it can be, and that’s the other reason we like the 12-cupper more. This smaller version doesn’t let you tinker with water temperature.
With its mid-century design and an exposed reservoir, you'll want to leave the Moccamaster out on the counter even when it’s not in use. But it doesn't just look great. Indeed, the pricey Moccamaster brews a complex and smooth pot of coffee that ranked highest in our taste test. This machine also fills a full pot quickly—a necessity for the morning rush.
Just getting into this whole “home barista” thing? Start off with the Delonghi BC0330T Combination Drip Coffee and Espresso Machine for pro level features that won’t break the bank. This machine pulls espresso shots, though it isn’t pod compatible like its big brother, the Café Nero (see above), and the “Swivel Jet” frother makes rich, creamy lattes and cappuccinos. It will brew 10 cups of drip coffee, and you can choose the strength of your java with the Accuflavor selector dial. Whether you opt for espresso or coffee, the advanced water filtration system eliminates chlorine for a tasty sip. Other convenient features found on more advanced models include a 24-hour programmable digital timer, pause and serve functionality, as well as a removable water tank for easy fill ups.
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.
