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.
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.
The dishwasher-safe, BPA free model from Takeya can brew up to a quart of concentrated cold brew coffee. It not only yielded one of the best tasting brews, it also aced our usability tests. The brewer is easy to set up, offers a durable build, and is simple to clean and store for later use. It is also the only brewer that is air-tight while it brews, allowing you to easily store the brewer on its side in a packed fridge.
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.
Help yourself to cafe-quality coffee every morning. Whether you're brewing coffee for two or making enough coffee for family and friends, the Hamilton Beach 12-Cup Programmable Coffee Maker is the perfect size and offers many features to fit your brewing needs. This full-size coffee maker looks great on the counter with a stainless steel design that fits right in with any kitchen.
This testing was designed to highlight the difference in how each machine extracted its coffee grounds. Remember, extraction is tied to water temperature, how long the grounds had to steep, and how evenly that water is distributed in the brew basket. (Depending on how the machine distributes the water and the shape of the basket, any particular ground may or may not receive the same amount of time in contact with water — thus any individual grind may be over-extracted, under-extracted, or just right.) Properly extracted grounds would have a balance of notes and aromas, from slight hints of acid to a pleasant amount of bitterness.

CR’s take: Like the model above, the Cuisinart Burr Grind & Brew takes whole coffee beans and grinds them fresh for each pot. It features programming, brew-strength control, a water filter, a permanent coffee filter, and auto-shutoff. This model earns a great rating for carafe handling. The stainless steel finish and glass carafe certainly elevate the experience of using it. Cuisinart brewers also received an Excellent rating for owner satisfaction. But the performance and finish come at a premium—this machine costs significantly more than the Black+Decker Mill & Brew.
