Percolators began to be developed from the mid-nineteenth century. In the United States, James H. Mason of Massachusetts patented an early percolator design in 1865. An Illinois farmer named Hanson Goodrich is generally credited with patenting the modern percolator. Goodrich's patent was granted on August 16, 1889, and his patent description varies little from the stovetop percolators sold today. With the percolator design, water is heated in a boiling pot with a removable lid, until the heated water is forced through a metal tube into a brew basket containing coffee. The extracted liquid drains from the brew basket, where it drips back into the pot. This process is continually repeated during the brewing cycle until the liquid passing repeatedly through the grounds is sufficiently steeped. A clear sight chamber in the form of a transparent knob on the lid of the percolator enables the user to judge when the coffee has reached the proper color and strength.

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.

In our quest to find the best, we pitted 10 highly regarded coffee makers against each other. These are the machines that regularly make it on best-of lists, earn accolades, and/or are recommendations from the coffee experts we talked to over the course of this review. We aimed for multi-cup carafes — no single serves — and drip machines only. (We didn’t want to muddy the results with French press, pour-over, or espresso. Those are for other reviews.)

Prior to the introduction of pre-measured self-contained ground coffee filter rings, fresh coffee grounds were measured out in scoopfuls and placed into the metal percolator basket. This process enabled small amounts of coffee grounds to leak into the fresh coffee. Additionally, the process left wet grounds in the percolator basket, which were very tedious to clean. The benefit of the Max Pax coffee filter rings was two-fold: First, because the amount of coffee contained in the rings was pre-measured, it negated the need to measure each scoop and then place it in the metal percolator basket. Second, the filter paper was strong enough to hold all the coffee grounds within the sealed paper. After use, the coffee filter ring could be easily removed from the basket and discarded. This saved the consumer from the tedious task of cleaning out the remaining wet coffee grounds from the percolator basket.

A drip coffee system is far superior to an instant coffee maker. For some, the smoother, less intense taste and aroma of a drip coffee system is a lot more palatable than the bitter coffee that tends to be produced by a French press. Not only that, but a drip coffee system is versatile – you can ground up your coffee beans to use in your system, and you can also buy premade blends.
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.
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.)
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.
It can take a little while to get to know the ins and outs of a new coffee maker. In CR’s labs, each drip coffee maker we test brews roughly 65 cups by the time our engineers are through with it. And brewing is just one of many aspects we look at. We test for handling and convenience, too, so you can choose a model that helps you sail through morning madness.
