Vacuum Coffee Makers

Maybe you are not satisfied with the traditional coffee. Perhaps you look for that little point of distinction and pleasure that the elaborations of artisan coffee give you. Then, yours are the vacuum coffee machines. In other fields, they are also known as cona or siphon coffee machines.

These Cona or vacuum coffee makers provide you with a different way of preparing coffee, completely manual. The result is a potent drink, with much more defined and intense aromas than in the coffees elaborated by filtration. In a vacuum system, the water boils only at 70 ºC (much lower than usual temperature) and this causes the coffee to retain all its organoleptic properties.

Those who try them are forever in love with their incredible results. Let’s see them!

NOTE: The Chemex is not a vacuum coffee maker in strict terms, since it does not execute a vacuum process at any time). We have decided to include it here because this is the segment that most resembles it and the result of the coffee is similar.

What is a siphon coffee maker made of?

You may think that siphon coffee makers are made of glass, the truth is that borosilicate glass is usually used in their manufacture. The reason for using borosilicate is that it resists up to 3 times more the sudden changes in temperature that occur during the process of brewing coffee in a vacuum coffee maker.

Components of a vacuum coffee maker

A coffee made with a siphon coffee maker usually has two parts or borosilicate glass containers, one upper and one lower, joined by a small pipe of the same material. There is also a filter where the ground coffee is placed, which is situated in the upper container. Finally, it is necessary to have a stove or an alcohol burner (also available with an electric base) that generates heat in the lower part of the coffee maker.

For siphon coffee machines, it is recommended to use a fine coffee grinder.

Vacuum coffee makers: How they work

In the lower container, the water is served. Underneath it there is a stove that applies heat to the water. The water will reach the boiling point and then rise to the upper container, mixing with the coffee and creating our favourite drink through an infusion process. It doesn´t happen by filtering, as occurs in drip or espresso coffee machines.

When this boiling point happens, it is when the game “vacuum” comes in. Haven’t you wondered until now why vacuum coffee machines are called that? Since we have to screw and seal the upper and lower containers well to create the vacuum. When all the coffee has risen upwards, stir a little with a spoon or non-metallic element, and extinguish the fire.

And now comes the exciting thing!

When the fire is extinguished, the air in the lower container will begin to cool, and it will absorb the coffee above by the effect of the vacuum. So at the end the coffee will be ready to drink deposited in the lower part of our siphon coffee maker.

That one is another of the main differences between vacuum coffee makers and other types of coffee makers such as Italian ones, where the coffee is always on top.

The siphon coffee, or vacuum coffee is very appreciated for its cleanliness. It is a bitter coffee although quite soft, free of impurities and very rich in nuances and aromas because the coffee is never in contact with any metallic element.

Inconveniences and advantages of a siphon coffee maker

Siphon coffee machines have very definite pros and cons. They are very fragile instruments, which can break both during handling (cleaning and storage) and by explosion when the glass is overheated, and the fire is not extinguished in time.

On the other hand, the two containers are tough to clean because they have narrow openings. Besides, you have to be careful: if you are going to vacuum clean a coffee maker, it is advisable not to use soap or toxic cleaning products.

The advantages of vacuum coffee machines are undoubtedly the excellent quality of the coffee they produce, pure and aromatic like few others. It is an elaboration that has part of ritual, and that falls in love with the real coffee lovers. As they do not need electricity, they are usually used to elaborate the coffee directly on the table, in front of the diners.

Cona coffee maker: What are they and why are they called like that?

When you go looking for information or buying vacuum coffee machines, you can sometimes read mentions or references to the Cona coffee maker (Kona coffee maker). It’s because Cona is one of the best known and most genuine manufacturers of this type of device. It was also one of the first companies to market them on a large scale around the world.

Cona type coffee machines are usually more resistant and more exclusive than those of other manufacturers because this company is only dedicated to working on this particular type of coffee maker. They preserve the purity of the original coffee machine: they only use glass in the elaboration of the coffee makers, to maintain 100% the purity of the coffee.

What is a cona coffee maker?

It is merely a cona brand vacuum coffee maker, which is characterized by the fact that only glass is used in its construction. Other manufacturers’ vacuum coffeemakers sometimes have metal parts that can affect the final taste or aroma of the beverage.

In an authentic Cona coffee maker, during processing, the coffee is never in contact with any material or any component other than glass.

Knowing the cona coffee maker: origin

Vacuum coffee makers had been around since 1830, but a little later, in 1840, a Scottish engineer by the name of Robert Napier designed his vacuum coffee maker. He called it nothing less than The Napier Vacuum Machine. And it turns out that the Scottish design became much more popular than all the vacuum coffee makers that existed to this day.

Years passed, and the company that kept the designs and spirit of Napier’s original coffee maker intact was Cona LTD, well into the 20th century. By derivation of the name of this old cona coffee maker, in the end, all the cona brand vacuum coffee makers ended up being called cona coffee makers.

Cona is not a type of coffee maker, but a brand that has ended up lending its name to the product.

It could be summed up like this: all cona coffee machines are vacuum, but not all vacuum coffee machines are cona coffee machines.

Where can I buy a cona?

On the Internet, the most natural way to buy a cona coffee maker is on Amazon. No many coffee stores are specializing in authentic cona or vacuum coffee makers.

These authentic cona machines are mostly marketed or distributed on this online platform. If you want to buy a cona coffee machine for home, you have an easy option:

Buy a vacuum coffee maker in Amazon, not necessarily of the cona type but of any other brand.

Vacuum coffee maker: Generic Price

The price of a siphon coffee maker is higher than the average for other types of coffee makers. The majority of coffee siphons are around 100 $ / £ , but depending on their size and their year of launch, they can even reach about 200 $/ £.

There are siphon coffee machines with 2 cups, 3 cups, or up to 4 and 5 cups. The size of the glasses determines Their capacity.

The japanese siphon or japanese coffee maker

These coffeemakers are also known as Japanese siphon coffee makers. The reason is not that Japanese siphons were invented in Japan, as we might first think, as they originated in Germany (dating from the first third of the twentieth century).

The problem is that these coffee machines quickly fell into oblivion and nobody paid much attention to them for much of the 20th century. It was the Japanese baristas and gourmets who began to rescue and start using vacuum coffee machines again. For this reason, they adopted the name of Japanese siphon coffee maker in the popular imagination.

And for this reason, Hario’s coffee makers are an absolute reference in this method of preparation. This recognition is also influenced by the exceptional quality of its crystal, of course.
