What is a Vacuum Coffee Maker and why does it make great coffee?

A Siphon, or vacuum coffee maker, is a “full immersion” brew system. That means instead of boiling the coffee it uses a constant heat source (the burner) to create an internal vacuum that moves the water from one chamber to the next.

One of the main advantages of a vacuum brewer is that the water never reaches boiling, which causes the coffee to lose some of its most subtle flavors. With a Siphon, once the burner is set the temperature remains constant for the entire brew-cycle. This full “immersion” method is ideal, as the coffee grounds are all immersed in the water for the same amount of time, with the same amount of heat, continuously.

The design boasts of two glass chambers, one filled with water and the second with grounds. Heating the lower chamber with the burner causes vapor pressure to increase.

Steam forces the water to rise into the upper chamber where the coffee grounds await. The water, now mixed with the grounds, is pulled back down through a filter into the lower chamber thanks to gravity (the “vacuum” effect) leaving you with tasty, perfectly brewed coffee when it’s finished. It’s delicious and it’s science!

siphon vs moka pot?

While a Moka Pot is a pretty cool device and does use pressure like a siphon, the Moka pot still utilizes boiling water to make its brew. Where a Moka has the ability to produce a strong espresso, the methods used in a siphon produce a remarkably cleaner coffee with just as much intensity. It really is all in the vacuum vs. boiling! You can clearly taste the difference.

a brief history of the Syphon coffee maker

Despite seeming like some newfangled hipster fad, siphon coffee makers – sometimes spelled ‘Syphon’ – have actually been around for some time. The concept dates back to the mid-1800s with the earliest known patent for a siphon-style coffee maker filed in Berlin in the 1830s.

Even then people agreed that boiling coffee diminished the flavor and several types of vacuum and vapor pressure machines were put into use.

The first commercially successful siphon brewer was designed and sold by French woman known as Madame Vassieux, popularizing this new method of coffee making during the late 1800s.

The method was more elegant and more theatrical; a satisfying spectacle for entertaining guests that was much more suitable for the time. And why shouldn’t we enjoy the same?

Go deeper: Other features to look for

You already know a lot about this magnificent gravity coffee maker. But here are a few interesting points.

Wondering what features to look for in a Siphon? When looking for the best best siphon coffee maker, here are a couple of interesting points when settling on your choice:

Electric Siphon Coffee Maker vs Stove-top

Choosing between a standalone electric Siphon or a stove-top is really a matter of preference and aesthetics. In terms of brew quality there isn’t much difference.

The Stove-top, as its name obviously implies, is designed to sit atop your stove, using its flame as the burner. These tend to be a bit more simple and less expensive than their flashier standalone counterparts. The standalone, on the other hand, has its own stand and built-in burner (using either gas or alcohol) that rests just below the bottom chamber where the water is kept. These tend to have bit more flair in their design but otherwise function just the same.

capacity & design

As with any coffee-maker, the brew amount you require is determined by your own particular needs. Vacuum coffee makers brew in various batch sizes, typically ranging from 3 to 8 cups per brew.

Who can deny the curious appeal of a siphon coffee maker? They’re exquisite, tastefully satisfying and make one stunning cup of coffee!
