One of the many issues with other coffee makers is that the brewing process is inconsistent, with temperature fluctuations that can potentially affect the acidity, aroma, and final flavor of your beverage. The OXO On Barista Brain Coffee Maker is fixed with an intelligent microprocessor that monitors ambient temperatures throughout the brewing process.
All the machines we tested came with either insulated carafes or glass pots with built-in warmers. Both have pros and cons. Glass pots are typically easier to clean because they tend to have wider mouths, and the lack of internal insulation means that glass pots will have a greater interior volume relative to its exterior volume — basically, it’s easier to get your hand or dish sponge into a glass pot. On the other hand, glass pots are more fragile and have to be heated from a base plate. In our tests, those base plates could even raise the temperature of the coffee, like with the CuisinArt, which can make coffee taste burnt.
CR’s take: Our highest-rated drip brewer with an insulated, thermal carafe, the Ninja Bar Brewer CF085 has plenty to recommend it. CR’s testers find that it offers superb brew performance and is very easy to use. In our member surveys, Ninja drip coffee makers received an Excellent rating for owner satisfaction. (We don’t yet have enough data to judge reliability.) This model has a full suite of features, including an unusual over-ice brew mode for making iced coffee. Ninja claims its thermal carafe will keep coffee hot for 2 hours, and the machine comes with a milk frother and a standalone French-press brewer. These features come at a price, of course; the Ninja Bar Brewer is the second most expensive model on this list.
The Bonavita Coffee Brewer performs stellar when it comes to coffee drip brewing, easily outpacing more expensive coffee makers. It'll take about six minutes to create 44 ounces of coffee. Brisk brewing has caught the attention of the Specialty Coffee Association of America, since it's threshold for recognition is a brewing time of fewer than eight minutes.
“This is simply an amazing machine. I have had NO trouble with it whatsoever. … The quality of the espresso is better than what I get out of the coffee shops — using their beans. It took me a long time to tune in the perfect cup of espresso/latte/cappuccino, and there are variables, but mostly in the beans you buy. I had to buy a decent burr grinder, but considering the investment in the machine, another $150 for a good burr grinder is nothing. I only run filtered water through the machine. I love this machine. I have poured over 2,500 shots through it. Not a single problem with the machine. Many mistakes by the operator, but I will take my espresso out of this machine before any store bought cup-o-Joe.”
When you’re looking for an espresso maker, you have a few different options. Electric espresso makers are popular choices, and they make creating your own espresso drinks quick and easy. This type of machine feeds pressurized water through a series of tubes in the device, heats it up and then feeds it through compacted grounds. Most electric espresso machines include milk frothing wands, which use steam to create delicious foamy milk or cream that’s ideal for cappuccinos or lattes. Many machines are fully automatic, so there isn’t much of a learning curve involved. A few even include built-in coffee mills, offering fresh coffee with zero effort.
Where MistoBox really shines is in its efficiently designed website and deep customization. If you want to, you can sign up for a scheduled delivery of curated espresso blends or single origin coffees and just let it ride—no input is necessary beyond the initial question of what kind of roast you like. But if you want to get a little more involved, you can rate each coffee you receive to refine future shipments or—if you want to take the future into your own hands—curate your own list of upcoming beans with a feature MistoBox calls the "Brew Queue." The number of choices is dizzying, and there are plenty of user reviews to guide your way thanks to a very active community.
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.
