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.
For all the debate over whether the best coffee comes from a Chemex or a French press or an AeroPress (even Nespresso), sometimes you just want to turn on a machine and let it do the work. We asked ten coffee drinkers — food-industry professionals and just plain coffee snobs — what’s the coffee machine that’ll get you a simple at-home brew without all the fuss?
I have to say that I'm very happy that I waited for this one! The espresso is excellent, the drinks have all been hot (even when adding milk from the Aeroccino), the whole spinning process takes about 15 seconds (or less) to pour into the cup, and - most surprisingly - the new coffee-sized cartridges are AWESOME! They taste NOTHING like regular, ground grocery-store coffee-in-a-can. They are much more flavorful, much stronger, and seem fresher even than using whole coffee with a grinder (maybe it's from being sealed in the aluminum cartridges?)."
“We really love this machine because we love great coffee, but we don’t make frothy milk drinks. This machine produces very, very good coffee from scratch at the push of a button, automatically grinding the beans pumping through hot water, and dumping out the “puck” of coffee grounds into the internal bin. It’s a nice compact size, and fits easily on a counter under the cabinets.”

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.
