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.
We’re the largest online retailer of espresso machines and it’s no secret why. We love coffee. We love that first sip in the morning, the one that you’ve got to fight to get to your mouth because 8 hours of sleep seems like a pipe dream. We love that rush, when the caffeine kicks in and you know that you’ve got the day in the palm of your hand. We love the art – brewing, roasting, tasting – and the journey that each coffee drinker takes in search of their perfect joe. We’ve been sharing that love with the world since 1997 and we hope you’ll pull up a cup and join us! If this sounds like the place you would love to work, see our latest job openings on our Careers Page!
If all you’re looking for is a gorgeous cup of coffee and no fuss, we strongly recommend the Bonavita BV1900TS. It’s the smallest machine among our top picks and, at $190, the cheapest. Even better, it ranked in the top three out of 10 during our taste tests. It’s also the simplest and most straightforward: one button you click to start brewing, and that’s it. You can’t program brew times; you can’t play around with water temperature; and it even lacks some convenient touches like a brew basket that attaches to the machine (when you’re done brewing, you have to place the brew basket on a plate or in the sink before it makes a total mess). But it’s by far the fastest machine out of our top picks, brewing up a full eight-cup pot in under six minutes. It’s a straightforward, high-end coffee maker that leaves little to complain about.

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.
