Product Information

Vacuum coffee brewers are part of the family of coffee makers which utilizes two separate chambers to produce vapor pressure and use it in a vacuum to produce a clear and delicious brew of coffee. These types of coffee makers have been used for over a century and were usually the main topic of conservations after meals due to their distinct appearance while coffee was brewed using these same vacuum pots. Take a look at some components of a vacuum coffee brewer in our article below.

A vacuum coffee brewer has four components:
1. The bottom container into which you pour the water
2. The top container into which you put the coffee grounds
3. The siphon tube that connects the top and bottom container
4. The filter, where the liquid and vapor pass through

The vacuum brew system works on the principle of the contraction and expansion of gas (the hot water vapor). Once the bottom container is heated, water vapor is created and that vapor works as a catalyst to push the water up the connection tube, through the filter to the top container. Once the water has been moved to the upper container, the water vapor escapes through the siphon tube. This escaping vapor works to stabilize the temperature of the water in the top chamber. It typically takes between two to four minutes for the process to get completed.

Once the heating process is complete, the water in the bottom container cools and contracts. This creates a vacuum and the suction pulls the liquid from the upper chamber to the lower chamber. Voila, the coffee is brewed!

Just like other coffee makers, vacuum pots come in different sizes ranging from pots that brew four ounces up to 48 ounces.

When vacuum pots were introduced they were heated up using a simple wick burner – those who hearken back to the original, still use wick-heated pots. Today’s vacuum coffee brewing pots can be used on the stove top or come with self-contained heating units with alcohol wick burners or butane burners.

Brewing coffee in a vacuum pot will take some trial and error to get your perfect cup, but they are a fascinating way to brew coffee! With more people opting to entertain at home and offer their guests a great cup of coffee following a home-cooked meal, a vacuum pot is as much a conversation piece as it is an appliance designed to brew an amazing cup of coffee. Your guests are sure to remember enjoying a cup brewed in a vacuum pot.
