Vacuum Coffee Makers – the most elegant, visual way to make a perfect cup of coffee.

Our very own Cona vacuum brewer. We love it, and the coffee it makes.

When one looks at a modern vacuum coffee maker, like the very elegant Cona coffee maker - pictured above - it is tempting to think that vacuum coffee making is a new technology.

Not so. Vacuum coffee makers were being used back in the eighteenth hundreds.

And during the nineteen hundreds the process was being refined by companies like Silex and Sunbeam.

But of one thing there is no doubt – a glass vacuum coffee maker, well designed, is elegant not only in its appearance, but also in how it works.

How vacuum coffee makers work...

Here’s the simple version.

- You put water in the lower chamber and ground coffee in the upper chamber.

- When heat is applied to the lower bowl, the water rises up a central stem and mixes with the ground coffee.

- When the heat is removed, and the pressure in the lower bowl falls, the hot water is sucked back down into the lower bowl, through a filter.

- You then serve the coffee from the lower chamber.

The whole process works through the rise and fall of air pressure within the chambers when heat is applied, and then removed. Hence the name – vacuum coffee maker.

Does a vacuum coffee maker make better coffee?

It certainly makes a very smooth cup of coffee, with very little sediment. And because of the simple laws of physics, it’s very hard to make a mistake while brewing this way. So you can be sure of a near perfect brew every time.

That said, the quality of the brew isn’t the only reason you might want to buy one of these beautiful devices.

Unlike chunky plastic drip brewers with all their buttons, LCD displays and memory chips, a vacuum coffee maker is just glass, with a small filter.

You can buy one with a built-in heating element, or place it on your stove or over an oil burner. 

No microchips. No plastic that is colored to look like metal. No gizmos or timers.

Just a beautifully designed, beautifully functional device in glass.

And to add to the pleasure even further, you can watch your coffee being brewed...from one glass chamber to another.

You'll see what I mean if you watch our video review of the Cona coffee maker.

So while you might want to hide your monstrosity of a plastic drip brewer on your counter...brewing coffee with a vacuum coffee maker adds a wonderful atmosphere when done over an oil burner on your breakfast table or dinner table.

It’s worth having one just for the simple pleasure of seeing it in action.

For entertaining, a brewer like the Bodum Santos Stovetop Glass Vacuum Coffee Maker is great.
