Espresso Machine: Coffee
built 486 days ago
Espresso machines are definitely not cheap, but, compared to going to Starbuck's every day, it may not take long at all for a good machine to pay for itself. Spending $3 every weekday at the local coffee house translates to $750 over the course of a year. You could buy a great machine for that amount that will last for years to come.

A handpresso is a small handheld high-pressure espresso machine. It works by pumping air at very high pressure (16 bar) into an intermediate chamber. Hot water is then poured into a small reservoir, which can contain hot water for one cup of espresso coffee (45ml). Ground coffee is inserted on top of the water reservoir and a portafilter is screwed on the top of the water reservoir. The machine is now turned around and the pressure from the intermediate chamber is released into the water reservoir. The high pressure forces the water through the coffee pod and into the cup, which is positioned underneath the device.

Starting life in the late '80s, Coffeetech initially operated as an espresso machine engineering business based in London. Huge customer demand soon drove the company towards the sales of equipment, and to meet this requirement the company negotiated UK distribution rights for Nuova Simonelli, Saeco and ECM espresso machines. Initially selling only direct to caterers and coffee shops, Coffeetech’s national engineering support soon came to the attention of the coffee roasters and coffee supply trade and the company’s activities became more focused on wholesaling to the coffee trade. This side of its activities now accounts for 90% of the company’s business.

While technically not an espresso producing device, so-called stovetop espresso makers produce a dark coffee with an extraction ratio similar to that of a conventional espresso machine. The bottom chamber contains the water. The middle chamber is a filterbasket and sits within the bottom chamber holding the ground coffee. The top chamber, with a metal filter, screws onto the bottom chamber. When the pot is heated on a stove, the pressure from the steam in the bottom chamber forces the water through a tube into the filter-basket, through the ground coffee, the metal filter, and it then funnels into the top chamber where the coffee is then ready to serve. Stovetop espresso makers produce dark coffee, but they usually lack the necessary pressure which creates a foam emulsion known as crema.

[E]xperts agree that you shouldn't even consider an inexpensive "steam driven" espresso machine. Only pump espresso machines make real espresso, say experts. Steam-driven machines are incapable of brewing true espresso because water is forced through coffee grounds at only 1 to 3 bars of pressure, far less than the 9 bars of pressure recommended for espresso. What you end up with, according to most experts, is strong coffee rather than espresso. If you're just after strong coffee, you should instead consider a moka pot like the Bialetti Moka Express (*est. $20) or a French press coffee maker, both of which are far less expensive than even a cheap espresso machine.
