What is Vacuum Coffee Maker
A vacuum coffee maker comes by many names. It is also known as a siphon coffee maker or vac pot.
It brews coffee using two containers, often made of glass. The coffee infusion is done using vapor pressure and gravity.
It seems like a weird mad scientist thing brewing coffee with a vac pot. But one thing’s for sure, anyone who has this thing for coffee will love the taste of freshly brewed Joe from a vacuum coffee maker.
Vacuum coffee maker has long been used since the 1800s. It is in the 1830s when the first vacuum coffee maker appeared and was invented by Loeff of Berlin.
Since then, the instrument was used in many parts of the world. But in 1840, a French woman named Marie Fanny Amelne Massot, also known as Madame Vassieux, patented the commercially successful vacuum coffee brewer.
The vacuum coffee brewer designed by Madame Vassiuex is made of two balloon-shaped glasses held together by a frame. Meanwhile, a Scottish inventor was also known as Napier, was also creating his version of the vacuum pot.
However, the Napier Coffee Pot has never patented. But in 1856, the Institution of Mechanical Engineers presented an award for Napier’s device.
The Napier Coffee Pot has a different design but works in the same principles as the vacuum pot by Madame Vassiuex. It’s in 1910 the two American sisters, Mrs. Ann Bridges and Mrs. Sutton, patented a device called Silex.
Silex is made of Pyrex, a glass manufactured by Corning Glass Works based in New York. The Silex vacuum brewer design is very much similar to the modern Hario Next siphon brewer.
Main Components of a Siphon Coffee Maker
- Upper Chamber – this contains the ground coffee, and it is where the steeping occurs.
- Lower Chamber – this is where the water is heated until enough pressure is produced for the gas-water mixture to go up through a tube connected to the upper chamber.
- Siphon Tube – the passageway connecting the upper and lower chamber.
- Filter – often made of steel or cloth, which filters ground coffee after the brewing process.
Heat is an essential component in the coffee siphon brewing process. Manufacturers use different types of heat sources for siphon coffee makers, depending on individual design.
- Wick Burner – It is the burner originally designed for the early siphon coffee makers. It uses kerosene or alcohol as fuel.
- Butane Burner – It uses butane gas and popularly used by most siphon coffee makers nowadays. Butane burner slowly heats the water, but it produces delicious coffee without the burnt taste.
- Electric Hot Plates – This heat source uses electricity to heat the siphon coffee brewing device. Modern vacuum coffee makers use this heat source for convenience and quick brewing.
- Stovetop (gas/electric) – Some siphon coffee makers are designed to work on stovetops using either gas or electric. Typically, siphon coffee makers that work with stovetops are those designed with a flat-bottomed lower chamber.
How Vacuum Coffee Makers Work
The weird-looking vacuum coffee maker is a fascinating contraption. Aren’t you curious about how this strange coffee maker works?
Let’s find out how.
Heating causes the water in the lower chamber to expand. This causes the vapor to go up to the upper glass chamber through the siphon tube and coffee filter.
Steeping the Ground Coffee
The condensation produced by the heating of water steeps the coffee ground in the upper glass chamber. This process extracts the coffee flavor.
After a few minutes of steeping the ground coffee, the heat is turned off. The cooling process starts.
As the lower glass chamber cools down, the difference between gravity and pressure creates a vacuum that sucks the coffee infusion quickly into the lower chamber.
The filter prevents the ground coffee inside the upper glass chamber to get sucked into the lower chamber.
Now the siphon coffee brewing process is done.
Frequently Asked Questions
Is vacuum coffee better?
Yes, vacuum coffee is better. Why?
There are several reasons why vacuum coffee is considered a better coffee.
First of all, a vacuum coffee maker produces delectable full-bodied cups of Joe. Since the 1800s, siphon coffee makers have been popular for producing exceptional coffee.
Another reason is you don’t have to spend so much on a vacuum coffee maker. For less than or a few hundred dollars, you can get a quality siphon coffee maker that produces great-tasting siphon coffee.
The process of using a vacuum brewer may be less straightforward. But the experience of coffee brewing like a laboratory experiment in a high school class brings you a different kind of excitement.
How does a vacuum coffee maker work?
The principle of brewing coffee using a vacuum is quite impressive. The heated water in the bottom chamber of the device creates pressure, thus pushing the water up to the upper chamber for steeping the ground coffee.
The contraption is removed from the heating source and cools down the glass chambers. The result is a difference in gravity and pressure that creates a vacuum.
The vacuum pulls down the steeped coffee passing through the filter and siphon tube, then back to the lower glass carafe. This finishes up the siphon brewing process.
What is siphon coffee?
Siphon coffee is the product of brewing using a siphon or vacuum coffee maker.
How to use a vacuum coffee maker?
The vacuum coffee maker is not so difficult to use. But it’s also not so straightforward.
Heating the Water
You put the desired amount of water in the bottom chamber. It is heated until water comes to a near boil.
Preparing the Coffee Grounds
While waiting for the water to heat up, an amount of ground coffee is put inside the upper chamber. The amount of ground coffee depends on how strong you want the brew.
Putting the Upper and Lower Chambers Together
As the upper and lower chambers are joined together, the heated water expands, and pressure builds up. This causes the hot water to come up through the siphon tube connected to the upper chamber.
Stirring the Coffee-Water Mixture
As the water goes up the upper chamber, the mixture of coffee and hot water is stirred for a maximum of one minute.
Finishing the Brewing Process
After stirring, the contraption is removed from the heat source. The brewing continues until the coffee infusion cools down.
Once the glass chambers cool down, the hot brew contracts and create a vacuum, the brew then is pulled down through the filter, then fills up the bottom glass carafe.
Now the siphon coffee is ready to serve and satisfy your cravings for a delicious cup of Joe.
