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.

Some machines come with all the accessories you need to make espresso, but others don't. Check to see if your machine includes any accessories before you buy them. You will need a grinder to have freshly ground espresso, a milk frother or a milk frothing pitcher if you like foamy milk for cappuccinos or lattes, and a tamper to press down the coffee grounds before you make espresso. We explain why you need each one and recommend which ones to buy below:


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.

If you're ready to pull the trigger on buying an espresso machine, be prepared to shell out a little cash. Espresso machines can be wildly expensive. Rightfully so. Pulling a perfect shot requires precision: the machine must maintain both precise temperature and stable pressure throughout the brewing process. Achieving this stability is difficult and requires complex machinery, which is why you can find machines for upwards of 6,000 dollars.

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.
CR’s take: Though this Bialetti lacks typical drip-machine features such as programming and brew-strength control, it more than compensates with a Very Good rating in our brew performance test and a crisp 8-minute brew time. If you’re the type who sometimes prefers a morning shot of espresso to a cup of joe, this twofer—drip machine beside espresso maker—may be for you. It features a built-in milk frother, a permanent coffee filter, and auto-shutoff. CR does not yet have enough survey data on Bialetti machines to rate them on reliability and satisfaction, but when we do, we’ll add that info to our ratings.
