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.
If you’re shopping for coffee at the grocery store, “check the roast date, rather than the ‘best by’ date,” says Awan. With mass market roasters, the “best by” date can obfuscate the window in which coffee beans are at their best: about 4 days after roasting, when some, but not all, of the carbon dioxide has escaped from the beans. (Too much carbon dioxide captured within beans tends to create uneven extraction, as the gas escapes — this is what pre-infusing tries to counter. Conversely, too little carbon dioxide in the bean can lead to a loss of flavor.)
“This little espresso maker is just awesome! It is fun to use and always makes a great cup of espresso. I’ve used it to make macchiatos, affogatos, and as a espresso shot to my coffee. The simplicity of this stovetop espresso maker is amazing. You won’t get as much crema as you would with an espresso machine but the aroma and taste are unmatched. I’ve had the three-cup model for a few months now, and I use it often. I’ve had no problems with it at all. After it use I just rinse it with warm water and let it air dry.”
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.
If you push the 54mm stainless steel portafilter into the hands-free grinding cradle, the grounds will go right into the filter. The grinder shuts off when it's done, too, so you don't have to worry about figuring out if you've got the right amount. Finally, the included 54mm tamper ensures that your grounds are evenly pressed, so you get the most out of your beans.
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.
Drip-style coffee makers already have a bit of a flavor handicap when compared with other brewing methods, like pour-over and French press, which give coffee drinkers ultimate control over every aspect of the brewing (and therefore extraction) process. This makes it even more important to select a high-quality coffee bean for your at-home drip coffee maker. To learn more, we spoke with Saadat Awan at Woodcat Coffee in Los Angeles.

The Baratza Encore is simplicity defined and our top coffee grinder. This burr grinder has a 40-setting grind size selector, an on-off switch for continuous grinding, and a push-button for manual control. That's it. Other grinders include complicated timers, built-in scales, strength adjustment sliders, and other doodads, but Baratza suggests that you don't need them—and they're right. Measure your beans using a separate scale, grind them fresh for each cup. That's the way to do it.
