The Rocket’s espresso lever is an upgrade from the simple on/off button used by most of our models. By only moving the lever part way up, you can play around with pre-infusing your coffee grounds before pulling the shot. Pre-infusion can be fun to tinker with as you try to home in on what makes your perfect espresso. This gives the Rocket an additional level of customization not available on the other models we tested.
With its mid-century design and an exposed reservoir, you'll want to leave the Moccamaster out on the counter even when it’s not in use. But it doesn't just look great. Indeed, the pricey Moccamaster brews a complex and smooth pot of coffee that ranked highest in our taste test. This machine also fills a full pot quickly—a necessity for the morning rush.
“Last night was a perfect test of the single-cup concept. I had already programmed and prepped my 3 a.m. standard coffee brew, however, I still wanted a cup of coffee. I switched over to the single cup and brewed my cup, then switched back and pressed the program button to ensure it would still brew the main pot at 3 a.m. Worked like a charm!! Before, I would have had to brew the entire eight cups that were ready, toss out most of it, and set up my morning brew all over again.”
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.
Served in a variety of drinks, espressos are made by machines that send pressurized hot water through finely-ground coffee beans—thus, the quality of the drink is dictated in large part by the quality of machine that brews it. Historically, the best espresso has been brewed in coffee shops with industrial-grade equipment. Today, continued innovation in the at-home espresso brewing industry has led to the creation of high-quality machines that can contend with some of the best baristas out there.
A portafilter (or group handle) attaches to the grouphead of semi-automatic and piston-driven espresso machines, and carries a tamped puck of coffee grounds within its basket. It is usually made of brass for better heat retention, and is attached by a plastic or wooden handle. The portafilter forms a seal with the espresso machine's gasket, and directs high-pressure hot water through the coffee puck. After-market retailers also sell bottomless portafilters that minimize the espresso's contact with any metal. A bottomless portafilter is one tool baristas use to analyze the quality of the coffee grind and the evenness of the extraction and allows for a visual check of "channeling" or the condition in which water is able to pierce a hole in the espresso puck during the brew process leading to poor extraction. Often, baristas use knockboxes to store their spent espresso grounds after they have pulled a shot.
An early variant technique, called a balance siphon, was to have the two chambers arranged side-by-side on a sort of scale-like device, with a counterweight attached opposite the initial (or heating) chamber. Once the near-boiling water was forced from the heating chamber into the brewing one, the counterweight was activated, causing a spring-loaded snuffer to come down over the flame, thus turning "off" the heat, and allowing the cooled water to return to the original chamber. In this way, a sort of primitive 'automatic' brewing method was achieved.
The gist: The Cisno is the perfect way to enjoy good espresso on the go and takes the spot as Amazon's Choice for portable espresso makers with 4.5/5 stars. This little guy is small enough to fit in a cup holder, yet pumps at 15 bars of pressure, powered by a rechargeable lithium battery. All you need are Originaline Nespresso capsules and some water. The process is super simple: Insert the Nespresso capsule, pour water into the 50ml water cavity, push the one big button on the Cisno, and boom— automatically pump and enjoy you cup of espresso. Tryna stay fancy? You still have the option of using your own coffee grounds if you get reusable stainless steel capsules.
CR’s take: Like the model above, the Cuisinart Burr Grind & Brew takes whole coffee beans and grinds them fresh for each pot. It features programming, brew-strength control, a water filter, a permanent coffee filter, and auto-shutoff. This model earns a great rating for carafe handling. The stainless steel finish and glass carafe certainly elevate the experience of using it. Cuisinart brewers also received an Excellent rating for owner satisfaction. But the performance and finish come at a premium—this machine costs significantly more than the Black+Decker Mill & Brew.
