Prior to the introduction of pre-measured self-contained ground coffee filter rings, fresh coffee grounds were measured out in scoopfuls and placed into the metal percolator basket. This process enabled small amounts of coffee grounds to leak into the fresh coffee. Additionally, the process left wet grounds in the percolator basket, which were very tedious to clean. The benefit of the Max Pax coffee filter rings was two-fold: First, because the amount of coffee contained in the rings was pre-measured, it negated the need to measure each scoop and then place it in the metal percolator basket. Second, the filter paper was strong enough to hold all the coffee grounds within the sealed paper. After use, the coffee filter ring could be easily removed from the basket and discarded. This saved the consumer from the tedious task of cleaning out the remaining wet coffee grounds from the percolator basket.
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.)
First, of all of the espresso machines we tested, the two Breville models are the only ones that contain the above-mentioned PID for extremely precise temperature control. This means that the machine consistently pulled a slightly-sweet, creamy shot of espresso. It had plenty of crema on top. Another reason this machine pulls such a consistently wonderful shot is that it maintains consistent pressure—where other machines made bitter, flat-tasting shots, the consistent pressure of the Breville machine meant the espresso was flavorful and delicious.
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.
We tested 12 models by making shots of espresso and lattes on each machine. We enlisted the help of an expert from Students of Coffee, a group of coffee educators and roasters at New York University, to judge for quality. The majority of the models we tested were semi-automatic, meaning brewers still have to grind the coffee and pack it in the portafilter (the little filter cup with a wand that you place in the front of the machine). Semi-automatic espresso machines heat the water for you, and then pump it through the grounds at varying levels of pressure, depending on the machine. The semi-automatic models we tester were:
Why it's great: The relatively lightweight machine by Mr. Coffee is a triple threat, meaning you’re not limited to just espresso. You can also make cappuccino and regular coffee, not to mention a variety of specialty drinks from the included recipe book (think espresso martinis, raspberry cappuccinos, choco-nutty lattes, etc.) The machine comes with an electric pump that shoots out 15 bars of pressure. It also has a one-touch feature that lets you select either a single or double-shot drink, and it even has an automatic milk frother with an adjustable knob, so you can customize the amount of froth you’d like in your drink of choice.
That said, it’s not as elegant to use as the OXO machines. (Nor is it as nice to look at. One tester described its tall, bulbous body and squat carafe as “UFO-like.”) Take its eight-button controls, for example, which you use to toggle among brew modes, scroll up and down within the menu, and engage a manual brewing feature. Programming it to start brewing at a certain time was about as intuitive as setting an alarm on a clock radio — easy enough, but more technical than sleek. OXO definitely feels like the future; Behmor is more, “If it ain’t broke, why fix it?”
The machine is super easy to use: just choose either a single or double shot, select your coffee grounds, fill the milk and water reservoir and choose your brew. The water reservoir is removable, allowing for easy fill-up in the sink. The Café Barista also boasts the fastest preparation time when compared to other Mr. Coffee espresso makers. And at less than $200, this model is WAY less expensive than some of its competitors, giving you a great bang for your buck.
Why it's great: As much as we appreciate freshly ground coffee beans for our espresso, let's be honest: when you *accidentally* snooze your alarm (five times) in the morning and don't even have time to brush your hair, chances are the last think you're gonna think about doing is grinding some freakin' beans. This could be a problem if you're someone (like me) who can't function without a strong dose of caffeine in the morning. However, not a problem with Nespresso. This life-saver heats up in less than 15 seconds and gets you tasty espresso at the push of a button. You get your quick fix without sacrificing quality.
CR’s take: If you like the look of black stainless steel, you can add a hit of the trendy finish to your kitchen with the Bella Ultimate Elite Collection coffee maker. Appearance aside, this model brews a fresh pot in just 9 minutes and is graceful in action, earning strong ratings in our carafe handling tests. It offers programming, brew-strength control, a pause-and-serve feature, and auto-shutoff. Bella drip machines also received a Very Good rating for predicted reliability. At about $50, this affordable, attractive option won’t disappoint.
