†Programmable Brew Time: Conventional wisdom frowns at grinding beans early and programming a pot to brew later. The aromatic compounds in coffee beans start to oxidize as quickly as 15 minutes after grinding, which causes coffee to start losing aroma and flavor. But Michael Ebert, senior consultant at Firedancer Coffee Consultants, LLC, assured us that, given the trade-offs for convenience, “grinding the night before will still make a great coffee — just not as great as it could be.” Seven of the 10 pots we tested are programmable, including three of our top picks (all but the Bonavita).
When it comes to features, our top pick’s little sister, the OXO On 9-Cup Coffee Maker, looks and feels much the same: a single-button dial, programmable start times — even the timer that lets you know how old the coffee is after it’s been brewed is identical. On this version, the water reservoir isn’t detachable, but it brews coffee significantly faster than the 12-cupper’s 14 minutes(!) and it’s $100 cheaper. It’s a great machine that didn’t earn our top spot simply because the coffee it makes didn’t perform quite as well as the other three top picks in our taste tests, and it doesn’t let you tinker with water temperature and extraction the way the larger machine does.
An electric drip coffee maker can also be referred to as a dripolator. It normally works by admitting water from a cold water reservoir into a flexible hose in the base of the reservoir leading directly to a thin metal tube or heating chamber (usually, of aluminum), where a heating element surrounding the metal tube heats the water. The heated water moves through the machine using the thermosiphon principle. Thermally-induced pressure and the siphoning effect move the heated water through an insulated rubber or vinyl riser hose, into a spray head, and onto the ground coffee, which is contained in a brew basket mounted below the spray head. The coffee passes through a filter and drips down into the carafe. A one-way valve in the tubing prevents water from siphoning back into the reservoir. A thermostat attached to the heating element turns off the heating element as needed to prevent overheating the water in the metal tube (overheating would produce only steam in the supply hose), then turns back on when the water cools below a certain threshold. For a standard 10-12 cup drip coffeemaker, using a more powerful thermostatically-controlled heating element (in terms of wattage produced), can heat increased amounts of water more quickly using larger heating chambers, generally producing higher average water temperatures at the spray head over the entire brewing cycle. This process can be further improved by changing the aluminum construction of most heating chambers to a metal with superior heat transfer qualities, such as copper.
Percolators began to be developed from the mid-nineteenth century. In the United States, James H. Mason of Massachusetts patented an early percolator design in 1865. An Illinois farmer named Hanson Goodrich is generally credited with patenting the modern percolator. Goodrich's patent was granted on August 16, 1889, and his patent description varies little from the stovetop percolators sold today. With the percolator design, water is heated in a boiling pot with a removable lid, until the heated water is forced through a metal tube into a brew basket containing coffee. The extracted liquid drains from the brew basket, where it drips back into the pot. This process is continually repeated during the brewing cycle until the liquid passing repeatedly through the grounds is sufficiently steeped. A clear sight chamber in the form of a transparent knob on the lid of the percolator enables the user to judge when the coffee has reached the proper color and strength.
This is an easy-to-use coffee maker that'll add some retro style to your countertop. It includes a pause-and-pour feature for times when you need caffeine before the brewing process is done — and after brewing, it keeps your coffee piping hot for 40 minutes (you can monitor the length of time on the indicator gauge on the front display). Available in black, cream, white and red.
For example, if your coffee tastes a bit salty or sour, the grounds are under-extracted, which can be remedied by a finer grind. But what if only some of your grounds are too coarse, and others are too fine – and maybe some are just right? Having uniform grind size throughout your brew basket makes it easier to isolate and adjust this variable in order to get the level of extraction you want. The only way to achieve that is with a burr grinder. Miller — as well as a handful of our other experts — recommends the Barazata Encore Coffee Grinder ($129).
The Moccamaster isn't for everyone. Handmade in the Netherlands, it costs around $300—and would never win an award for value. It lacks a programmable timer, and it was also bit more difficult to set up than the rest of the coffee makers—in fact most were ready to go right out of the box. But a quick look at the instruction diagram should clear up any confusion, and the end result is well worth the effort.
“So simple and easy to use. I’ve had the older version for ten years, tested out and researched so many to try something different only to return to this one, and I have no regrets. I LOVE IT! Most coffee makers put out a lot of steam at the top, which is unfortunate when stored under a cabinet. This has zero steam on top of the coffee maker. Also, most water reservoirs have a lid that flips open, which is also inconvenient when stored under a cabinet. This lid slides side to side, and brews a whole pot of coffee in about three minutes. Very convenient for busy, on-the-go, impatient people like me.”
very surprised that you did not include the Behmor Brazen Plus Temp Controlled Coffeemaker. Better price then many that you have listed and it offers so many extras, including a pre-soak. I buy pricey coffee, even Geshas when affordable so need a good coffee maker and suggest testors try this one too to see if they feel it is worthy of adding to the list
It’s obvious, but easy to forget: If you don’t clean out your coffee machine’s carafe after each use with soap and water, you’ll always end up tasting a little bit of yesterday’s now-bitter brew. Thermal carafes need to be hand-washed, but all the plastic components of our top picks — brew baskets, lids, etc. — are dishwasher-safe if you keep them on the top rack.
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.
“This is the same coffee maker that I bought years ago. And it’s even the same price. Yep — they do still make things like they used to. And they last forever. It’s super simple, super reliable, compact, and cheap. There are a lot of places where we can spend money, but a simple cup of coffee doesn’t have to be one of them. Once you get the amount of water and coffee figured out to your taste — simply do that. No K-cup, nothing to recycle, fits the car cup holder. And the coffee stays hot in the mug.”
For many of us, the daily grind can't begin until we've had that first cup of piping hot coffee—so the right brewer is at the top of the list. The most basic coffee makers make at least a decent cup, but a little more money buys conveniences such as programmability, a thermal carafe to keep coffee hot longer, settings that let you adjust brew strength, and more.
