In the realm of coffee gear, a coffee siphon is both a novel experience and an excellent brewing tool.
It’s not as commonly used as an espresso machine or a drip filter - understandably so. We’ll get into the pros and cons of this brewing method later in the post.
First, let’s understand a bit about the siphon coffee maker.
Also called a vacuum pot, this brewer was invented in the 1830s in Germany by Leoff. It was then commercialised in the 1840s by Madame Vassieux in France. There was a time when it was used primarily in Europe and America before it was replaced by more convenient and quick options.
Later, the siphon brewer was rediscovered in Japan during the 20th century and still enjoys a fair share of the market.
How Does a Siphon Coffee Maker Work?
The siphon coffee maker looks like something straight out of a lab and the brewing has a ceremonial feel to it. That’s partially why it still receives praise from coffee enthusiasts.
This system typically has two glass chambers, one on top of the other, held together by a brass structure. It relies on vapour pressure to brew coffee.
To start using the vacuum pot, fill the bottom chamber with water and switch on the heat. This can be in the form of an alcohol or butane burner which is placed underneath the lower chamber.
Next, place the cloth filter in the top chamber and fix it onto the bottom chamber. It is important to make sure that the two chambers are secured firmly.
Gradually, you’ll notice that as the water starts to boil, the vapour forces the water up through the tube and into the top chamber. Now is the time to add the ground coffee to it.
Stir the grounds into the water gently so that it is evenly mixed and the extraction occurs properly.
Let this mixture brew for 60–90 seconds. The time can vary depending on the size of the siphon brewer and the volume of coffee you’re trying to make.
Here’s where it gets even more interesting. After the required brewing time is over, you have to remove the heat source. Inevitably, the lower chamber starts to cool, which creates a vacuum.
The brewed coffee then gets pulled down and you’ll find that the grounds remain on the filter in the top chamber.
You can detach the top portion and use the bottom chamber as a coffee pot to serve.
It is a delight to watch the science of this brewing method. The more you try, the more quickly you’ll discover what works best for you in terms of trying different roasts, tweaking the brewing duration, and bringing out the flavours you’re looking for in a cup.
Pros and Cons of Using a Siphon
The main pro of using a siphon brewer is that it gives you more control over the brewing process. You can customize the grind size and brew time as per your preferences.
This method also produces a clean cup with great clarity of flavour. It is visually appealing and makes you focus more on the act of brewing coffee. Therefore, it ultimately encourages mindfulness with regards to coffee consumption.
Although the setup in itself is a bit elaborate, it can be a durable option for the long run if you maintain it well. Since it’s not mechanised, you won’t need to be worried about maintaining different parts.
One of the many disadvantages of using a siphon coffee maker is that it’s not easy to get accustomed to. The brewing process in itself can be a little complex and it’ll probably take you several uses to figure out how to brew coffee correctly.
Moreover, this method will inevitably require you to spend some time and effort to clean the equipment. Most coffee consumers are deterred by this as they are in the habit of drinking coffee daily, and so having to clean the equipment frequently is not something they’re ready to sign up for.
You also need an external heat source, which adds to the number of elements you have to keep in mind. Consequently, this is not a portable or travel-friendly option.
Who Should Be Using the Coffee Siphon?
From the pros and cons listed above, you’ve probably got an idea as to whether the siphon brewer is right for you or not.
This brewing method is suitable for people who prefer a more slow, ritualised coffee experience. You have ample time and energy to devote towards learning a new gear, or don’t mind doing some trial and error.
Also, if you’re tired of regular coffee makers and want a setup that allows you more freedom to customize the brewing process, then the siphon coffee maker is for you.
