In our quest to find the best, we pitted 10 highly regarded coffee makers against each other. These are the machines that regularly make it on best-of lists, earn accolades, and/or are recommendations from the coffee experts we talked to over the course of this review. We aimed for multi-cup carafes — no single serves — and drip machines only. (We didn’t want to muddy the results with French press, pour-over, or espresso. Those are for other reviews.)
Bunn-O-Matic came out with a different drip-brew machine. In this type of coffeemaker, the machine uses a holding tank or boiler pre-filled with water. When the machine is turned on, all of the water in the holding tank is brought to near boiling point (approximately 200–207 °F or 93–97 °C) using a thermostatically-controlled heating element. When water is poured into a top-mounted tray, it descends into a funnel and tube which delivers the cold water to the bottom of the boiler. The less-dense hot water in the boiler is displaced out of the tank and into a tube leading to the spray head, where it drips into a brew basket containing the ground coffee. The pourover, water displacement method of coffeemaking tends to produce brewed coffee at a much faster rate than standard drip designs. Its primary disadvantage is increased electricity consumption in order to preheat the water in the boiler. Additionally, the water displacement method is most efficient when used to brew coffee at the machine's maximum or near-maximum capacity, as typically found in restaurant or office usage. In 1963, Bunn introduced the first automatic coffee brewer, which connected to a waterline for an automatic water feed.
“What I REALLY like about it is that it’s pretty much an all-in-one system without the thousand-dollar-plus all-in-one cost. I push one button and all the magic happens, and it’s quite entertaining to watch the espresso cascade through the milk and create separate layers. I also like that I can take the milk and store it in my fridge. I’ve done some temperature tests, and only noticed a five-degree increase after making a double latte, before I put it back in the fridge. This is nice, as you would think that to be so close to all that heat, it would be a much bigger temperature fluctuation.”
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.
