The single-serve or single-cup coffeemaker has gained popularity in recent years. Single-serve brewing systems let a certain amount of water heated at a precise temperature go through a coffee portion pack (or coffee pod), brewing a standardized cup of coffee into a recipient placed under the beverage outlet. A coffee portion pack has an air-tight seal to ensure product freshness. It contains a determined quantity of ground coffee and usually encloses an internal filter paper for optimal brewing results. The single-serve coffeemaker technology often allows the choice of cup size and brew strength, and delivers a cup of brewed coffee rapidly, usually at the touch of a button. Today, a variety of beverages are available for brewing with single-cup machines such as tea, hot chocolate and milk-based specialty beverages. Single-cup coffee machines are designed for both home and commercial use.
Throughout the latter part of the 20th century, a number of inventors patented various coffeemaker designs using an automated form of the drip brew method. Subsequent designs have featured changes in heating elements, spray head, and brew-basket design, as well as the addition of timers and clocks for automatic-start, water filtration, filter and carafe design, and even built-in coffee grinding mechanisms.
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.
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 gist: Taking the first spot on our list is the Breville BES870XL. This machine is no joke and its 4.3 star Amazon rating from over 1,800 reviews speaks to that. It boasts a 15 bar Italian pump and a 1600 watt thermo coil heating system. It comes with a 54mm tamper, a stainless steel conical burr grinder, and a 2-liter removable water tank. It's available in three colors: black, red, and silver.
It scored the highest in our out-of-the-box taste test, brewing coffee our tasters described as “light” with subtle notes of blueberry, citrus, cherry, tobacco, and hazelnut. The machine simply brews great coffee, and it takes its job seriously. If you’re interested in playing around with the flavor and extraction of your roast, the Behmor Brazen gives you more access to more variables. You can adjust water temperature, play with pre-infusion times (15 seconds to four minutes) — it even has you enter your altitude to better determine water’s boiling point, and calibrate its internal thermometer during setup.
"I have used this machine for about a week, and it is awesome! I had used an espresso machine frequently years ago, but got sick of the grinding, prepping, priming, etc., especially before work in the morning. So, I eventually gave up and bought a plain-ole coffee maker. Unfortunately, "regular" coffee, to me, tastes like hot water. I even tried a Kuerig, but returned it within a month - it was more convenient, but the coffees are no higher quality than any grocery-store brand coffee. So I debated for a long time about whether I should wait for one of these brand-new Nespresso Vertuoline machines, or just buy one of the older, espresso-only Nespresso machines.
Thankfully we have Amazon, and moreover Amazon users (aka fellow espresso connoisseurs) who happen to be very vocal when it comes to their favorite machines. (We have read dozens of reviews and these folks are THOROUGH, to say the least.) To save you some time, we put together a list of the best espresso makers based on Amazon reviews. Our number one favorite was the Breville BES870XL. Not only does it take the spot of "best of the best" on Amazon's ranks page, its ease of use, freshness factor, and straight up *amazing* espresso-making capabilities have reviewers swooning.
Tamp: To ensure the espresso is evenly packed, your machine comes with a tamp, which you’ll press into the basket against the grounds. This step is important: When you pull a shot, the water will go to the place of least resistance, avoiding densely packed areas. This denser espresso won’t be properly saturated, making it under-extracted and sour, while the looser espresso will be over-extracted and bitter.
“We are a Cuisinart family. My mom still has the same food processor from the 1980s on the counter. When my co-host (and brother) Darin and I were looking for a coffee maker for our studio, that was the only choice for us. We loved this one because you set the time and forget it. We always work late, so this is a really nice end-of-day step, and then you get going without the bleariness of the morning. The thermal is a must as we drink throughout the day, and it’s great to just have it hot when we’re ready.” — Greg Bresnitz, co-host of Snacky Tunes
Why it's great: With the exception of a few exterior differences, getting the Inissia is basically like getting the Pixie at a discounted price. Aside from the quality espresso, it comes with all the same Nespresso perks: The Nespresso welcome kit has 14 unique capsules and access to the Nespresso club. Through the Nespresso Club you can order capsules either online or by phone, as well as get personalized advice and technical support for your machine 24/7. Not too shabby for a tiny little machine of its price. For those who don't mind being a little less fancy with the exterior design, the Inissia is definitely a great option.
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.
Some machines come with all the accessories you need to make espresso, but others don't. Check to see if your machine includes any accessories before you buy them. You will need a grinder to have freshly ground espresso, a milk frother or a milk frothing pitcher if you like foamy milk for cappuccinos or lattes, and a tamper to press down the coffee grounds before you make espresso. We explain why you need each one and recommend which ones to buy below:
Brewing coffee has never been easier with this Black & Decker 12-Cup Switch Coffee maker. With the switch of a button, you’re coffee will start brewing into the reinforced glass Duralife™ carafe with a comfort grip handle. Grab a cup of coffee on the go with the Sneak-A-Cup™ feature, otherwise your coffee will be ready when you are with the Keep Warm carafe nonstick carafe plate.
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.
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.
