A vacuum coffee maker uses a strong flavor and perfectly mixes water and coffee. It consists of two glass pots, with the bottom one filled with water and the top one with coffee grounds. The pots are sealed and heated, then left to mix for 3-4 minutes. The cooling process creates a vacuum, and the coffee can be served from the bottom pot. This process is considered superior to other brewing methods and has become popular again in recent years.
A vacuum coffee maker uses a process that cooks coffee with an extremely strong flavor. That said, the flavor and strength of coffee is usually determined by the amount of coffee you use. While many coffee makers destroy flavor by not mixing the components properly, a vacuum cleaner is said to mix water and coffee perfectly.
A vacuum coffee maker consists of two mixing units, usually made of glass: an upper pot and a lower one. The upper plate sits directly above the lower one and are sealed together with a cap. A filter and tube are attached to the top pot and the tube hangs between the two pots.
This type of coffee maker uses ground coffee, usually with a rough texture. Coffee grounds are added to the top cup. How much coffee you use depends on how strong your favorite flavor is. A rounded tablespoon of coffee per cup of water will usually suffice if you like your coffee extra strong.
Next, the bottom bowl is filled with water and placed on a heating element until it almost reaches boiling point. Then, the top pot can be placed on the bottom pot and sealed. The increase in pressure in the lower pot caused by boiling will cause the water to rise through the hanging pipe and flow into the upper pot and start the fermentation process.
The water and coffee should be left to mix for about three to four minutes. Preparation time depends on how much you like the taste of your coffee. If you’re new to using a vacuum coffee maker, experimenting with time scales should eventually produce the desired results.
Remove the percolator from the heating element and the cooling process will cause a vacuum in the bottom pot. The water will seep back into the bottom vessel. As the water percolates, most of the coffee grounds will be filtered out, although some may remain in the water.
You can now separate the two pots and the bottom pot can be used to serve the coffee. The biggest benefit to enjoy when using a vacuum coffee maker is that the temperature used is perfect for making the coffee. Unlike some other brewing processes, such as the drip technique, none of the coffee’s oils and flavors are lost.
The vacuum coffee maker is considered superior to many other coffee brewing processes. The famous Santos vacuum coffee maker, designed by Swedish designer Kass Kleeson, is a staple in almost every Scandinavian home. The explosion of coffee over the past decade has brought this almost forgotten process back into popularity.
