Vacuum Pot Coffee – The Art of Syphon Coffee Brewing
Spread the love

There is the art of making great coffee, and the art of the vacuum pot that makes delicious coffee with a process that’s a wonder to behold. Vacuum pot coffee has been around for a while, first making its appearance in the mid 1800s, but eventually it lost in popularity to simpler methods. The arrival and convenience of drip coffee machines pushed it further into the background, but the vacuum coffee brewer has made a comeback.

Also called syphon or siphon, this is one of the best coffee brewing methods around. Sure it does require a careful approach that can’t match the push-button convenience of drip coffee, but the unique taste of vacuum pot coffee is reward enough for the work that goes into preparing it.

Vacuum Pot Coffee Basics – Best Coffee Brewing Method

First thing you should know about brewing a vacuum pot is that it’s going to look like a rad chemistry experiment from the Victorian era. That should fit, considering the year of its invention was mid-19th century. It’s probably not the choice for your daily cup, but vacuum pot brewing is your friend for the odd occasion, especially when you have friends over.

A vacuum brewer has four basic components:

  • Bottom container
  • Top container
  • Siphon/Syphon
  • Filter

Of course, there is more to brewing siphon filter coffee than those four components. To brew a good cup, you will also need the following:

  • Coffee beans (obviously)
  • Grinder
  • A burner – preferably a butane burner
  • Thermometer
  • Timer
  • Flat stirrer

The Science Behind Vacuum Pot Coffee Brewing

As the name very well implies, the method relies on vacuum (suction) to create the excellent cup of coffee you love so much. Water is added to the bottom container, and the siphon and top container are fixed. Once it begins boiling, the water has nowhere to go except follow the siphon into the top container. Coffee grounds are added to the water in the top container, while the water in the lower container continues to boil.

Once heat is removed from the lower container, the vacuum left by the vapor and water travelling to the top container works with gravity and sucks in the water-coffee mixture from the top container, pushing it through the filter. The filter removes the grinds, and the lower container gets the coffee you want.

Step by Step To Creating a Perfect Vacuum Pot

Step 1 – Add Water

Add water to the bottom container. Most containers come with markings to indicate the number of cups they’re going to make, so take your pick. It might be a good idea to pre-heat the water you add. You will have to boil the water, and a stove might just move things along faster than starting with a burner.

Step 2 – Turn On Heat

Place the burner and set it on high. There’s a chance you got a wick-burner when you bought your vacuum pot brewer. Push that thing away and use a butane burner.

Step 3 – Prepare Filter and Top Container

Firmly place the filter in your top container. Loosely place the funnel inside the lower container, at an angle. Wait for the water to boil.

Step 4 – Measure and Grind Coffee

Measure and grind your coffee, preferably to medium coarseness.

Step 5 – Attach Top Assembly

Once the water begins to boil, attach the top container securely to the assembly. Soon enough, water will start flowing upwards into the top container and it will begin to fill. Some water will remain in the bottom container, you do not need to be concerned about that.

Step 6 – Measure Temperature and Add Coffee

Once the top is full, use your handy thermometer to take a temperature reading. Ideally, you want the water at 195-200 degrees Fahrenheit. Once you hit the right temperature, add coffee and give it a good stir with a flat stirrer so as to saturate all grounds. Start the timer.

Step 7 – Lower the Heat

Depending on your personal preference, though usually between 40 seconds to 1 minute, give the coffee a gentle stir to make sure everything is completely saturated. Now turn down the heat.

Step 8 – Turn the Heat Off

At about a minute and thirty seconds, turn the heat off. Now that there is no heat, the vacuum pot starts sucking all the water back, pushing the mix through the filter. Your coffee will start flowing down into the lower container/globe, and will be done in about another one or two minutes.

Enjoy the fruits of the effort you put into the best brewing method!

Don’t be Afraid to Experiment

Like any other preparation, vacuum pot brewing can be changed to suit your cooking instinct and taste. Feel free to adjust the amount of coffee, filter and even the brewing temperature.

Maintaining And Cleaning Your Vacuum Pot Brewer

Your vacuum pot uses some specialty equipment, and as such needs special care. You might want to buy cleaning supplies when you purchase your vacuum pot, as that will save you a lot of trouble looking for the right cleaning equipment. Depending on the model you are using, you might need to use a curved steel rod brush. You should avoid using steel wool on the glass components of your vacuum pot coffee maker.

Be extra careful when you scrub and clean the containers and various pieces as they can easily break. If you’re using cloth filters, rinse the filter thoroughly and place it in water. Store in your refrigerator.

When you start brewing your coffee, make sure the containers are completely dry. When you add water to the lower container, there is a good chance some of it will end up on the outer side as well. Clean and dry the outer surface well before you turn on the heat.

Your vacuum pot is a complex setup that rewards you with delicious coffee. Remember to be careful when brewing the coffee, and take good care of your vacuum pot brewer to increase its life and longevity.
