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.
A best seller in its category, this espresso maker from Mr. Coffee has all the bells and whistles you could want out of a machine. Besides espresso, you can also make cappuccino or a latte at the touch of a button. There’s an adjustable cup tray that lets you change the height based on the size of your cup, and the milk and water reservoirs are removable for easy refill and cleanup. A drip catcher will keep things clean if anything spills over, and the machine comes with a single shot filter, double shot filter, measuring scoop, tamper, and coffee recipes.
There’s a coffee machine for everyone in our stylish and modern range: with pause-and-serve functions, 24-hour timers and larger carafes for up to fourteen cups, our coffee machines can be used in a variety of settings, from your kitchen counter to your office area. The water level indicator means you can choose exactly how many cups to brew, so there’s no need for anybody to go without, and nothing is wasted.
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.
The well-designed Braun BrewSense came closer to the gold standard for water brewing temperature than almost any other drip coffee maker in our testing, and delivered a rich, bold and hot cup of coffee. It has settings to program the coffee to brew ahead of time and you can adjust the brew strength and the temperature of the warming plate. Also available in black.
‡Pre-Infusing: Pre-infusing is a technique where the dry coffee grounds are initially saturated with hot water, allowing a “bloom” of carbon dioxide to escape. This 45-second(ish) process puts hot water into contact with more surface area around each ground throughout the brewing process, as it’s no longer competing with the escaping gas bubbles. It can improve the quality of the final product, since this more uniform contact creates a more even extraction. It’s a feature that six of the 10 pots we tested incorporated into their designs — as well as all four of our top picks.
As legend has it, Ethiopian goats were the first to discover the delightful properties of coffee beans when they ate the raw beans right off the stem. The goats nibbled happily away at the beans, probably right around 2 o'clock every afternoon, until finally an astute goat herder noticed the goats' perky behavior, gave the beans a taste, found them quite stimulating, and rushed them off to the nearest monastery.
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.
Espresso machines can be intimidating. We wanted something that did not require reading a novel-sized manual, watching a lot of YouTube videos, or reading tons of articles about espresso pulling. Yes, making espresso does require some learning for the home brewer. That's part of the fun, but the machine shouldn't be discouraging and impossible to use out of the box.
The OXO On 12-Cup feels high-tech without being high maintenance. It’s beautifully constructed, with silicone gaskets, a stainless steel carafe, and sturdy-feeling plastic. But let’s go ahead and get its biggest downside right out there in the open. Of the 10 machines we tested, it took the longest to brew eight cups of coffee — nearly 15 minutes. It heats its entire reservoir of water to temperature before a drop touches the grounds, and if you’re jonesing for a full pot to start off your day, that wait is going to feel like a lifetime. This was particularly noticeable considering four of the machines we tested brewed the same amount of coffee in less than half that time. The Bunn BTX-B Velocity Brew could do it in three minutes flat.
There’s also no way to adjust the temperature of the water on the Bonavita, or tinker with any of the other variables some of our other top picks gave access to. And that’s the other downside to this excellent machine: What you get is what you get, and if you do want to experiment with the flavor of your coffee, it will depend entirely on the beans you buy and the size you grind them to. Good thing the coffee it brews right out of the box is so dang good.
For first-time espresso machine owners, the Breville offers the perfect balance between hand-holding and customization. You’re in charge of basic steps like measuring out and pulling your shot, but the Breville makes it easy to adjust things like the coarseness of your grind and the amount of espresso. The user manual walks you through every step of the brewing process, and altering the default settings is easy, thanks to a display panel that clearly labels all buttons and lights. Our shots were beautifully layered and gave us truly gorgeous colors as the espresso flowed out of the portafilter.
A steam-driven unit operates by forcing water through the coffee by using steam or steam pressure. The first espresso machines were steam types, produced when a common boiler was piped to four group heads so that multiple types of coffee could be made at the same time. This design is still used today in lower-cost consumer machines, as it does not need to contain moving parts. Also, steam-driven machines do not produce as high of a pressure for extraction compared to pump-driven. This results in the crema, a hallmark of an espresso, being of lower quality.
There were lots of innovations from France in the late 18th century. With help from Jean-Baptiste de Belloy, the Archbishop of Paris, the idea that coffee should not be boiled gained acceptance. The first modern method for making coffee using a coffee filter—drip brewing—is more than 125 years old, and its design had changed little. The biggin, originating in France ca. 1780, was a two-level pot holding coffee in a cloth sock in an upper compartment into which water was poured, to drain through holes in the bottom of the compartment into the coffee pot below. Coffee was then dispensed from a spout on the side of the pot. The quality of the brewed coffee depended on the size of the grounds - too coarse and the coffee was weak; too fine and the water would not drip the filter. A major problem with this approach was that the taste of the cloth filter - whether cotton, burlap or an old sock - transferred to the taste of the coffee. Around the same time, a French inventor developed the "pumping percolator", in which boiling water in a bottom chamber forces itself up a tube and then trickles (percolates) through the ground coffee back into the bottom chamber. Among other French innovations, Count Rumford, an eccentric American scientist residing in Paris, developed a French Drip Pot with an insulating water jacket to keep the coffee hot. Also, the first metal filter was developed and patented by French inventor.
A portafilter (or group handle) attaches to the grouphead of semi-automatic and piston-driven espresso machines, and carries a tamped puck of coffee grounds within its basket. It is usually made of brass for better heat retention, and is attached by a plastic or wooden handle. The portafilter forms a seal with the espresso machine's gasket, and directs high-pressure hot water through the coffee puck. After-market retailers also sell bottomless portafilters that minimize the espresso's contact with any metal. A bottomless portafilter is one tool baristas use to analyze the quality of the coffee grind and the evenness of the extraction and allows for a visual check of "channeling" or the condition in which water is able to pierce a hole in the espresso puck during the brew process leading to poor extraction. Often, baristas use knockboxes to store their spent espresso grounds after they have pulled a shot.
Moka pots, also known as stove top espresso makers, are similar to espresso machines in that they brew under pressure and the resulting brew shares some similarities, but in other respects differ. As such, their characterization as "espresso" machines is at times contentious, but due to their use of pressure and steam for brewing, comparable to all espresso prior to the 1948 Gaggia, they are accepted within broader uses of the term, but distinguished from standard modern espresso machines.
CR’s take: If you need only one or two cups of coffee each morning and you don’t want a pod coffee maker, consider the Technivorm Moccamaster Cup-One Brewer. Compact and clean-lined, it has a profile that makes some sense of its high price (it retails for more than $200), and it’s a superstar when it comes to reliability. Technivorm was one of only three drip machine brands to earn an Excellent rating for predicted reliability in our member survey. Our testers also give this machine a strong score for brew performance. This model has only one simple feature (auto-shutoff) and it’s not the easiest machine to use, but you can count on it to last.
