The method for making coffee in a percolator had barely changed since its introduction in the early part of the 20th century. However, in 1970 General Foods Corporation introduced Max Pax, the first commercially available "ground coffee filter rings". The Max Pax filters were named so as to compliment General Foods' Maxwell House coffee brand. The Max Pax coffee filter rings were designed for use in percolators, and each ring contained a pre-measured amount of coffee grounds that were sealed in a self-contained paper filter. The sealed rings resembled the shape of a doughnut, and the small hole in the middle of the ring enabled the coffee filter ring to be placed in the metal percolator basket around the protruding convection (percolator) tube.
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.

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.
Once you start brewing, it makes a really, really good pot of coffee. Our taste test revealed the OXO On 12-Cup coffee was “dark and strong” and appealed to the more traditionalist coffee palates. The great flavor comes from the brewing process. The OXO machines have wide shower heads with multiple ports through which water streams, dispersing it evenly throughout the brew basket. Lots of other coffee makers spout water through just one hole, or through shower heads with a smaller radius, which can increase the chances of uneven extraction.
Dedicated to the best in all things brewing, Capresso presents the new Capresso Perk, a contemporary upgrade of the classic percolator. The Capresso Perk features elegant, durable stainless steel construction, with a view-through glass lid that showcases the percolating process. It brews 4 to 12 cups of piping, hot coffee in less than a minute per cup. Its automatic keep-warm function ensures that coffee is ready whenever you want it. Percolators are making a comeback, for entertaining, ease of...
One of the many issues with other coffee makers is that the brewing process is inconsistent, with temperature fluctuations that can potentially affect the acidity, aroma, and final flavor of your beverage. The OXO On Barista Brain Coffee Maker is fixed with an intelligent microprocessor that monitors ambient temperatures throughout the brewing process.
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.)
Water quality also plays a massive role in the way your coffee tastes. As we discovered in our review of the best water filters, water isn’t tasteless. Total dissolved solids (TDS) are what give “good tasting” water its sweetness — in fact, the SCAA recommends water with 150 milligrams per liter of TDS to brew coffee. (Want to check your water? A TDS reader is only about 15 bucks.)
Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.
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.
