Its straightforward ethos is conceptualized in the simple design and operations of the machine. You can conveniently pour up to 44 ounces or 1.3 liters of water into the water tank, then add spoonfuls of your favorite coffee grounds to the basket, and finally flip the switch and sit back as you see the water slowly travel from the tank over to the shower head
The principle of a vacuum brewer was to heat water in a lower vessel until expansion forced the contents through a narrow tube into an upper vessel containing ground coffee. When the lower vessel was empty and sufficient brewing time had elapsed, the heat was removed and the resulting vacuum would draw the brewed coffee back through a strainer into the lower chamber, from which it could be decanted. The Bauhaus interpretation of this device can be seen in Gerhard Marcks' Sintrax coffee maker of 1925.
In later years, coffeemakers began to adopt more standardized forms commensurate with a large increase in the scale of production required to meet postwar consumer demand. Plastics and composite materials began to replace metal, particularly with the advent of newer electric drip coffeemakers in the 1970s. During the 1990s, consumer demand for more attractive appliances to complement expensive modern kitchens resulted in a new wave of redesigned coffeemakers in a wider range of available colors and styles.
The machine itself is large, but not as monstrous as some of the other grinders I tested. It's also very bottom-heavy, which makes it feel more durable than other machines and means it won't rattle all over your counter while grinding. The heavy-duty translucent plastic collection cup generates less static cling than the glossy clear plastic cups I tested, and the chute that connects the burrs to the cup collects less debris than other models. Cleaning is simple: Just remove the top burr and use the included wire brush to remove residual grounds.
On August 27, 1930, Inez H. Pierce of Chicago, Illinois filed patent for the first vacuum coffee maker that truly automated the vacuum brewing process, while eliminating the need for a stove top burner or liquid fuels. An electrically heated stove was incorporated into the design of the vacuum brewer. Water was heated in a recessed well, which reduced wait times and forced the hottest water into the reaction chamber. Once the process was complete, a thermostat using bi-metallic expansion principles shut off heat to the unit at the appropriate time. Pierce's invention was the first truly "automatic" vacuum coffee brewer, and was later incorporated in the Farberware Coffee Robot.

“Self-identified coffee snob. Couldn’t be happier. Easy to operate, functions as advertised, instructions are clear. The metal filter included does what it needs to do. I recommend a relatively coarse grind (imagine the feel of cornmeal) with the metal filter to get the full flavor of the coffee. If you’re a bit of a coffee snowflake (no disrespect intended) and don’t like the ‘mud’ at the bottom of the cup, you should stick with the paper filter. Either way, the coffee maker itself does the job nicely.”
Access the world of coffee for inspiration. The De’Longhi combination coffee espresso machine allows you to use either coffee pods for a speedy messfree espresso, or freshly ground beans if you prefer your coffee brewed the traditional way. Espresso is delivered straight to the cup in seconds, perfect every time. The distinct sign of an ideal espresso is its ‘crema’, a creamy, toffee-colored layer that seals in flavor. Your De’Longhi espresso machine will deliver a crema that reflects the quality of the espresso, and the machine that made it. Fancy topping your espresso with a sweet milk foam? It’s easy to brew creamy lattes and velvety cappuccinos too, thanks to our patented cappuccino system frothers.
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.

CR’s take: Though this Bialetti lacks typical drip-machine features such as programming and brew-strength control, it more than compensates with a Very Good rating in our brew performance test and a crisp 8-minute brew time. If you’re the type who sometimes prefers a morning shot of espresso to a cup of joe, this twofer—drip machine beside espresso maker—may be for you. It features a built-in milk frother, a permanent coffee filter, and auto-shutoff. CR does not yet have enough survey data on Bialetti machines to rate them on reliability and satisfaction, but when we do, we’ll add that info to our ratings.
