Tamp: To ensure the espresso is evenly packed, your machine comes with a tamp, which you’ll press into the basket against the grounds. This step is important: When you pull a shot, the water will go to the place of least resistance, avoiding densely packed areas. This denser espresso won’t be properly saturated, making it under-extracted and sour, while the looser espresso will be over-extracted and bitter.
"This machine has turned me into a bonafide coffee snob. While it took some time to tweak all of the essential dimensions (water temp, grind size, coffee amount, draw time, basket type, etc.), I now make the most delectable coffee on earth because of this gorgeous contraption. It's the first thing I think about when my eyes open in the morning. I've ditched all of the other coffee-making paraphernalia in my kitchen (french press, grinders, baskets, pour-over devices, and others . . .) because they pale (literally) in comparison to the gold that comes out of this happy faucet. If my apartment goes up in flames and I have to escape quickly down the fire escape, my espresso machine is coming with me."
The term dual boiler is used narrowly for machines with two separate boilers, and more broadly for what are more properly called dual heater (DH) machines,[citation needed] featuring a boiler for brewing and a separate thermoblock (TB) for heating brew water to steaming temperature – opposite to HX machines, where the boiler is at steaming temperature and is cooled to brewing temperature.

Flavorful, hot beverages are a cornerstone of the restaurant industry.

By following this buying guide, you can find the best hot beverage equipment to make sure your business is serving the drinks that'll turn one-time customers into regulars.

"Love the Flair. Bought about a month ago and have been dialing in my home roasted espresso routine. The crema production is unrivaled even with commercial machines costing 5x more. Any shot less than spectacular is due to user error or inadequate grinds/bean quality. Using this device has been a treat and I thoroughly enjoy the fun ritualistic aspect. There is something to be said for physically pressing out all those tasty flavors rather than letting a machine. Owning the flair puts you in full control of every single aspect of the shot and allows for pressure profiling which no device can do cost effectively. Highly recommend the signature chrome and it looks stunning as a permanent countertop staple. Just found out you can make espresso with room temperature water that produces some outstanding results."

The gist: This "all-in-one" machine includes pretty much everything you need to make quality espresso, minus the beans. It's Amazon's choice for "espresso and cappuccino maker combos" and has a rating of 4.1 stars. It comes with its own electric bean-grinder, a 1.25 liter removable water tank, a measuring spoon and tamper, a stainless steel filter with two basket options, a stainless steel milk frothing cup, and two 3.6-ounce espresso cups. The machine brews espresso with 15 bars of pressure and with the Thermoblock fast heating system, it's ready to use in 45 seconds. The two portafilter baskets allow you to pull either a single or double shot drink. 

The well-designed Braun BrewSense came closer to the gold standard for water brewing temperature than almost any other drip coffee maker in our testing, and delivered a rich, bold and hot cup of coffee. It has settings to program the coffee to brew ahead of time and you can adjust the brew strength and the temperature of the warming plate. Also available in black.
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.
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.

The Mr. Coffee Optimal Brew coffee maker System has a highly modular design, with its rectangular water reservoir easily sliding in and out of the chassis. For those who only want a cup of basic coffee, you will find that the Mr. Coffee Optimal Brew coffee maker System will do that very well – its "brew now" button is found on the front of the machine.
“This little espresso maker is just awesome! It is fun to use and always makes a great cup of espresso. I’ve used it to make macchiatos, affogatos, and as a espresso shot to my coffee. The simplicity of this stovetop espresso maker is amazing. You won’t get as much crema as you would with an espresso machine but the aroma and taste are unmatched. I’ve had the three-cup model for a few months now, and I use it often. I’ve had no problems with it at all. After it use I just rinse it with warm water and let it air dry.”
Because the coffee grounds remain in direct contact with the brewing water and the grounds are filtered from the water via a mesh instead of a paper filter, coffee brewed with the cafetiere captures more of the coffee's flavour and essential oils, which would become trapped in a traditional drip brew machine's paper filters.[3] As with drip-brewed coffee, cafetiere coffee can be brewed to any strength by adjusting the amount of ground coffee which is brewed. If the used grounds remain in the drink after brewing, French pressed coffee left to stand can become "bitter", though this is an effect that many users of cafetiere consider beneficial. For a 1⁄2-litre (0.11 imp gal; 0.13 US gal) cafetiere, the contents are considered spoiled, by some reports, after around 20 minutes.[4] Other approaches consider a brew period that may extend to hours as a method of superior production.

Throughout the latter part of the 20th century, a number of inventors patented various coffeemaker designs using an automated form of the drip brew method. Subsequent designs have featured changes in heating elements, spray head, and brew-basket design, as well as the addition of timers and clocks for automatic-start, water filtration, filter and carafe design, and even built-in coffee grinding mechanisms.

When it comes to features, our top pick’s little sister, the OXO On 9-Cup Coffee Maker, looks and feels much the same: a single-button dial, programmable start times — even the timer that lets you know how old the coffee is after it’s been brewed is identical. On this version, the water reservoir isn’t detachable, but it brews coffee significantly faster than the 12-cupper’s 14 minutes(!) and it’s $100 cheaper. It’s a great machine that didn’t earn our top spot simply because the coffee it makes didn’t perform quite as well as the other three top picks in our taste tests, and it doesn’t let you tinker with water temperature and extraction the way the larger machine does.
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.
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.
There’s also no way to adjust the temperature of the water on the Bonavita, or tinker with any of the other variables some of our other top picks gave access to. And that’s the other downside to this excellent machine: What you get is what you get, and if you do want to experiment with the flavor of your coffee, it will depend entirely on the beans you buy and the size you grind them to. Good thing the coffee it brews right out of the box is so dang good.
Like the OXO machines, it has only one button on its interface. Unlike the OXO machines, that button does only one thing: start the brewing process. If you hold it down until it blinks, you’ll activate the pre-infusion; otherwise a simple click gets it going. Brewing a full pot of eight cups took us about seven minutes, by far the fastest of any of our top picks — which is a good thing, considering you can’t program it to start brewing before you wake up.
CR’s take: The Cuisinart Coffee on Demand is a self-serve model. It stores 12 cups of brewed coffee in a reservoir and has a dispenser instead of a carafe. It makes sense in homes where people are drinking coffee at different times; it keeps coffee hot and ready, so family and guests can fill their own cups. This model is programmable and features a water filter and a cleaning indicator. The reservoir can be removed for washing. In our tests, the Coffee on Demand performs quite well, receiving a Very Good rating for convenience. At less than $100, it can be a terrific choice for entertaining.
