Domestic electrification simplified the operation of percolators by providing for a self-contained, electrically powered heating element that removed the need to use a stovetop burner. A critical element in the success of the electric coffee maker was the creation of safe and secure fuses and heating elements. In an article in House Furnishing Review, May 1915, Lewis Stephenson of Landers, Frary and Clark described a modular safety plug being used in his company's Universal appliances, and the advent of numerous patents and innovations in temperature control and circuit breakers provided for the success of many new percolator and vacuum models. While early percolators had utilized all-glass construction (prized for maintaining purity of flavor), most percolators made from the 1930s were constructed of metal, especially aluminum and nickel-plated copper.
Our top pick is the OXO On 12-Cup Coffee Brewing System. It’s a large machine – both in footprint and in capacity — but it earned the second-highest scores in our taste test, and is sleek both to look at and to operate. Convenient features like programmable auto-brewing, a removable water reservoir that doubles as a kettle, and a spigot that stops the brew mid-stream if you remove the carafe make this machine feel high tech without being high maintenance. For those who want to be a little more hands-on with the brewing process, its single-button dial also lets you adjust the water’s brewing temperature, giving you more access to experiment with extraction and flavor.
As with any appliance, newer models are constantly getting rolled out. The newer Nespresso VertuoPlus coffee machine became available since I got my original Pixie. But I'm so pleased with mine — from the important stuff (like how well it makes my coffee), to the superficial stuff (like how it looks) — that I can't think of a single reason why I should change what I've got going on right now.
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.
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.

“This little coffee maker is PERFECT! So easy and reliable. It works great for a household with little kitchen space and light coffee drinkers. It has upped my coffee intake because it’s so easy to make coffee now! Plus, to be able to have it waiting in the morning and encourage me to actually get out of bed on time is well worth the price of this little machine.”

The OXO is SCAA-certified, so we knew going in that it would heat water to the right temperature range and let coffee brew for the right amount of time. But what really sold us on the OXO was how its scrolling dial made even that customizable. Assuming you want to bring the extraction down a touch for lighter, subtler coffee, you can lower the water temperature with a twist of the dial. Likewise, if you want a slightly more robust aroma from your brew, you can increase the water’s temp the same way.

Coffeemakers or coffee machines are cooking appliances used to brew coffee. While there are many different types of coffeemakers using a number of different brewing principles, in the most common devices, coffee grounds are placed in a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot, a cooking pot in the kettle family. Cold water is poured into a separate chamber, which is then heated up to the boiling point, and directed into the funnel. This is also called automatic drip-brew.
‡Pre-Infusing: Pre-infusing is a technique where the dry coffee grounds are initially saturated with hot water, allowing a “bloom” of carbon dioxide to escape. This 45-second(ish) process puts hot water into contact with more surface area around each ground throughout the brewing process, as it’s no longer competing with the escaping gas bubbles. It can improve the quality of the final product, since this more uniform contact creates a more even extraction. It’s a feature that six of the 10 pots we tested incorporated into their designs — as well as all four of our top picks.
All the machines we tested came with either insulated carafes or glass pots with built-in warmers. Both have pros and cons. Glass pots are typically easier to clean because they tend to have wider mouths, and the lack of internal insulation means that glass pots will have a greater interior volume relative to its exterior volume — basically, it’s easier to get your hand or dish sponge into a glass pot. On the other hand, glass pots are more fragile and have to be heated from a base plate. In our tests, those base plates could even raise the temperature of the coffee, like with the CuisinArt, which can make coffee taste burnt.
CR’s take: If you’re an aficionado of fresh ground coffee, this Black+Decker is the brewer to buy. As the name suggests, the Mill & Brew goes that extra mile, grinding whole coffee beans just before brewing. As a result, the machine is capable of making a great pot of coffee. Made of plastic with stainless steel accents, this model is easy to use and to clean, earning a Very Good rating in our convenience tests. It allows you to adjust brew strength, and it’s programmable, so you can set it to grind and brew just before you wake up.
