This testing was designed to highlight the difference in how each machine extracted its coffee grounds. Remember, extraction is tied to water temperature, how long the grounds had to steep, and how evenly that water is distributed in the brew basket. (Depending on how the machine distributes the water and the shape of the basket, any particular ground may or may not receive the same amount of time in contact with water — thus any individual grind may be over-extracted, under-extracted, or just right.) Properly extracted grounds would have a balance of notes and aromas, from slight hints of acid to a pleasant amount of bitterness.
Great for active, busy lifestyles, it’s Great for active, busy lifestyles, it’s the BLACK+DECKER Personal Coffeemaker. It brews single Servings of your favorite coffee directly into the 16-oz. Travel mug, which fits most car cup, holders. The permanent grounds filter is compatible with coffee grounds and pre-packaged soft pods, and it’s easy to rinse clean in the sink. The one-touch operation quickly delivers the morning coffee you need, with a compact design that’s perfect for small...
It’s not that cone filters won’t make a great cup of coffee — the OXO On 9-Cup still ranked fifth out of 10 in our taste test. But flat bottoms generally allow for the grounds to be more evenly extracted and increase the coffee’s flavor. (It’s no coincidence our other three recommendations have flat-bottom brew baskets). You may have to do a little more tweaking to get this coffee maker’s brew to the best it can be, and that’s the other reason we like the 12-cupper more. This smaller version doesn’t let you tinker with water temperature.

In later years, coffeemakers began to adopt more standardized forms commensurate with a large increase in the scale of production required to meet postwar consumer demand. Plastics and composite materials began to replace metal, particularly with the advent of newer electric drip coffeemakers in the 1970s. During the 1990s, consumer demand for more attractive appliances to complement expensive modern kitchens resulted in a new wave of redesigned coffeemakers in a wider range of available colors and styles.


The machine itself is large, but not as monstrous as some of the other grinders I tested. It's also very bottom-heavy, which makes it feel more durable than other machines and means it won't rattle all over your counter while grinding. The heavy-duty translucent plastic collection cup generates less static cling than the glossy clear plastic cups I tested, and the chute that connects the burrs to the cup collects less debris than other models. Cleaning is simple: Just remove the top burr and use the included wire brush to remove residual grounds.
For example, if your coffee tastes a bit salty or sour, the grounds are under-extracted, which can be remedied by a finer grind. But what if only some of your grounds are too coarse, and others are too fine – and maybe some are just right? Having uniform grind size throughout your brew basket makes it easier to isolate and adjust this variable in order to get the level of extraction you want. The only way to achieve that is with a burr grinder. Miller — as well as a handful of our other experts — recommends the Barazata Encore Coffee Grinder ($129).
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.
