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.
Mr. Coffee doesn’t ask for the 15- to 30-minute boiler warmup like some big-name brands, instead taking just five to 10 minutes. This is ideal both for your morning coffee routine and your quick after-dinner latte or late-night hot chocolate. The machine also boasts a simple milk-steaming method that requires less work than our other picks: Prep your espresso, pour your milk into the milk reservoir, and you can press a button and walk away. Your latte or cappuccino will be ready in less than a minute. The foam quality is on the lower end, but you can customize how much of it you want.
A refinement of the piston machine is the pump-driven machine, which was introduced in the Faema E61 in 1961, and has become the most popular design in commercial espresso bars. Instead of using manual force, a motor-driven pump provides the force necessary for espresso brewing. Espresso machines are made to accept water directly from a cold water line supply, common in commercial installations, or from a separate tank that must be filled with water by hand. The latter is more common with lower-volume commercial installations and domestic espresso machines. Due to the required high pumping pressure and precision flow control needed, the particular type of electric pumps typically used are known as solenoid-piston pumps. These pumps are classified as a positive displacement type (general category) of pump.
An evenly tamped shot requires the tamp to fit into its portafilter basket precisely. Each machine comes with its own tamp, so we were surprised to find that not all of them fit. Some were too small, leaving behind a crescent moon of untouched coffee. It’s possible to try and compress in sections, but you’ll run the risk of re-tamping some of the grounds and producing an unpalatable shot.
Its straightforward ethos is conceptualized in the simple design and operations of the machine. You can conveniently pour up to 44 ounces or 1.3 liters of water into the water tank, then add spoonfuls of your favorite coffee grounds to the basket, and finally flip the switch and sit back as you see the water slowly travel from the tank over to the shower head
Some machines use a single boiler kept at steaming temperature, but water for brewing is passed through a heat exchanger, taking some heat from the steam without rising to the same temperature. Although the water for brewing remains at a lower range than that required for steaming milk, it is still too hot for proper coffee extraction without first cooling; thus this type of machine requires a cooling flush of 4–6 seconds prior to the first espresso pull. Once the machine is dialed into the proper temperature, as many shots can be pulled as required without refreshing. However, if the user leaves the machine idle again for some period, the flushing process will need to be repeated. The HX variety is found in many mid-range machines and many users install thermometers to assist them is dialing in correct temperatures. There is some controversy as to the temperature stability of the brewing water, since it is indirectly converted from steaming temperature to brewing temperature, rather than kept at a brewing temperature.
Conceptually, MistoBox splits the difference between many other coffee subscriptions—and it's our best coffee subscription box because of it. The company doesn't roast its own beans, but instead sources them from top roasters all across America, who ship the fresh-roasted coffee direct to your door. It doesn't ask you to participate in blind tastings, and it doesn't give you a detailed quiz up front. It's all about balance.
Let’s circle back to that extra-long brew time. There are two factors that didn’t make it an automatic “no” for us. The first is that the OXO On 12-Cup is programmable. Like our experts say, grinding coffee in advance isn’t going to make the most perfect cup of coffee. But the fact that you can program the machine’s “wake-up time” to start brewing and have coffee ready when you are takes the sting out of the wait.
A grouphead (or group head) is the receiver for the removable portafilter (or group handle). A typical consumer espresso machine normally has only one grouphead, while popular professional machines, such as those used at commercial coffee shops, can contain anywhere from one to seven. During the process of extracting a shot of espresso, hot water is forced through the grouphead under pressure. The grouphead contains many holes (the shower) that attempt to distribute the pressurised water evenly over the surface of the grinds in the portafilter basket and thereby achieve an even cross sectional flow.
CR’s take: This Cuisinart drip coffee maker with a stainless steel finish and glass carafe earns an Excellent rating for brew performance. It’s programmable and features a water filter, a permanent coffee filter, cleaning mode, a cleaning indicator, and auto-shutoff. The machine also allows you to adjust the strength of your brew. For the money, this model offers style and features that are hard to beat. If you can live without the built-in grinder of the Cuisinart Burr Grind & Brew above, you can save yourself some money and still enjoy Cuisinart quality for a lot less.
