Why it's great: Bialetti is a trusted name brand in the motherland of espresso: Italy. According to their page, you can find a Bialetti product in nine out of ten households in Italy. Point being: they know a thing or two about a quality machine. The Bialetti Stovetop is really nothing fancy. No electronics, no buttons to push. Just fill the bottom chamber with water, fill the second chamber with ground coffee beans, put it on the stove, and wait for the coffee to start coming out the top. Boom. The coffee is fresh and the machine maintenance is basically nothing.
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.
The tall tower is fixed on a rectangular base, with a water tank that looks something akin to a trapezoid. The hard plastic funnel allows your favorite paper filters to fit inside of it. It is recommended that you use type 4 paper filters, however. You also have the option to use permanent gold filters if you want to move away from reoccurring costs.
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.
Domestic electrification simplified the operation of percolators by providing for a self-contained, electrically powered heating element that removed the need to use a stovetop burner. A critical element in the success of the electric coffee maker was the creation of safe and secure fuses and heating elements. In an article in House Furnishing Review, May 1915, Lewis Stephenson of Landers, Frary and Clark described a modular safety plug being used in his company's Universal appliances, and the advent of numerous patents and innovations in temperature control and circuit breakers provided for the success of many new percolator and vacuum models. While early percolators had utilized all-glass construction (prized for maintaining purity of flavor), most percolators made from the 1930s were constructed of metal, especially aluminum and nickel-plated copper.
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.
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.
