This grinder produced the most even grounds out of all the machines I tested, and its range of output is all-encompassing. The coarsest setting produces large flakes, while the finest setting produces puffy grounds akin to powdered sugar—perfect for Turkish coffee. In between, I was quickly able to find the ideal settings for my Hario Woodneck, Aeropress, and even mason jar cold brew.
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.
For hundreds of years, making a cup of coffee was a simple process. Roasted and ground coffee beans were placed in a pot or pan, to which hot water was added, followed by attachment of a lid to commence the infusion process. Pots were designed specifically for brewing coffee, all with the purpose of trying to trap the coffee grounds before the coffee is poured. Typical designs feature a pot with a flat expanded bottom to catch sinking grounds and a sharp pour spout that traps the floating grinds. Other designs feature a wide bulge in the middle of the pot to catch grounds when coffee is poured.
Although it's very easy to use — you just fill the portafilter with grounds, attach it to the machine, and press the button to start — The Gaggia Classic isn't as flexible or intuitive as the Breville Barista Express. The user manual is less detailed, too, so you have to have a basic idea of what you're doing or browse the internet for tips. The machine has a one-year warranty if you run into problems.
Pierce's design was later improved by U.S. appliance engineers Ivar Jepson, Ludvik Koci, and Eric Bylund of Sunbeam in the late 1930s. They altered the heating chamber and eliminated the recessed well which was hard to clean. They also made several improvements to the filtering mechanism. Their improved design of plated metals, styled by industrial designer Alfonso Iannelli, became the famous Sunbeam Coffeemaster line of automated vacuum coffee makers (Models C-20, C-30, C40, and C-50). The Coffeemaster vacuum brewer was sold in large numbers in the United States during the years immediately following World War I.
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.
“I purchased the machine for myself as a birthday present, and I’ve had it for about six weeks. We have a Pavoni espresso machine, which my husband loves for his espressos, but I think it’s a pain for making lattes: grinding the beans, tamping down the pod, ‘pulling’ the lever (which will be really hard if you tamp it too densely), steaming the milk, and then cleaning the steaming wand, not to mention what a pain it is to refill the water chamber (turn off, wait till pressure is gone, then you can refill). Why am I listing all of these steps? Because that’s what you don’t have to worry about with the Lattissima! Here are my steps now: Turn on the machine, get the milk container out of the fridge and plug it into the front, put an espresso capsule in the top, stick a mug under the spout, and push the Latte button. Done. You do need to clean the frother, which is just putting another cup under the spout, turn the milk to “clean” and let it clean, then you can remove the milk container and stick it in the fridge. I clean the milk container once a week, soaking all the pieces in a bowl of hot, soapy water for a few hours.”
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.
“I am a coffee snob, and one of my favorite things about traveling to Europe is their espresso and cappuccinos. A couple years ago, I bought a Nespresso Aeroccino machine for making froth and a stovetop Moka pot for making espresso; the system has worked fine, but the espresso can take awhile to make (around 5-8 minutes) and there’s definitely a learning curve to making good coffee with it. … [How] does this machine do [in comparison]? Stellar. Absolutely stellar. Once the water is in and it heats up, you flip up a lever, drop in the pod, and press the size button (espresso or lungo). Off it goes! Brewing is super quick and the espresso always comes out with a beautiful crema on top. My first drink was a cappuccino, and it was so much better than the ones I’ve been making with my Moka pot! …
Programmable coffee makers exist to make the brewing process as painless as possible. Outside of maybe grinding your coffee beans, the drip coffee system will use optimal water temperatures of around 205 degrees Fahrenheit or 96.11 degrees Celsius for maximum extraction of the ground coffee beans. The best automatic coffee maker will seamlessly reach this temperature within minutes of the brewing process.
