Chemex 101: Brewing Tips And More

Chemex is maybe one of the most fundamental and useful coffee makers in the world that inevitably makes everyone fascinated about it. It is not only a simple coffee brewer but also a delicious coffee maker. Just like other coffee makers, it has its own brewing style and therefore tips and tricks. What’s more, it has special coffee filters that can upgrade your coffee to the next level. Then let’s see what is Chemex and other things that a coffee lover needs to know about it.

What Is Chemex?

Chemex coffee maker is invented by Peter Schlumbohm in 1941. It is a manual pour-over style glass coffee brewer and it is manufactured first by the Chemex Corporation in Chicopee, Massachusetts.

In 1958, After 17 years of its production, it is accepted as “one of the best-designed products of modern times” by the designers at the Illinois Institute of Technology. What’s more, in New York City, it is included in the collection of the Museum of Modern Art.

Although Chemex sizes can change when it comes to its design, we can say it is a glass flask shaped like an hourglass and the handle of this hourglass is wrapped in wood with a leather tie. With its simple yet clever design and its usefulness, it is not surprising to see it in a museum.

Being one of the best coffee makers, Chemex brings out flavor from the coffee beans using the heat and slow saturation process. It also has some special filters to ensure that you don’t have some sediment leftovers in your coffee.

How Does Chemex Work?

Not surprising, it works similarly to other pour-over coffee makers but there is one exception. The Chemex filters are inserted into the brewing vessel itself. The slender design of the Chemex and the fact that it uses a dense filter slow down the flow of water.

You put the coffee grounds in the filter and pour the water slowly. The resulting coffee is contained in the bottom of the vessel and ready to be served. You may wait a little bit longer when brewing your coffee using Chemex because of the restricted flow but this longer time allows your coffee to be more tasteful.

What Makes Chemex Special?

As we mentioned above, it could be the best coffee maker in the world. But why? Let us explain.

Chemex brewing gives us a cup of coffee that tastes better than other coffee makers because of its unique filter and shape as well as its glass design. The fact that it is made of glass ensures that there are no additional flavors in your cup and you are tasting pure coffee. If you are in the pursuit of clean and pure coffee, you might love Chemex.

Another thing that makes this coffee brewer special is that it can create a smoother cup with less bitterness without losing the body. Chemex coffee is very bright and clear compared to other coffee makers so it might be the best choice if you want a clean cup of coffee.

What Size Chemex Should You Buy?

The classic Chemex pour-over comes in four sizes. 3-cup, 6-cup, 8-cup, and 10-cup model. The difference between the 6-cup, 8-cup, and 10-cup sizes is the size of the belly of the Chemex, that is, the bottom part. The 3-cup model is smaller but it has a cone (top part) with a different angle. This cone influences the way the water saturates so it affects the taste of your coffee a little bit.

In conclusion, if you want to brew single servings (10-15 ounces), you might find 6-cup the most useful. Most people use 6-cup and 8-cup models because they are enough to make coffee for 1-2 people or even more.

What About Chemex Filters?

Chemex coffee filters are one of the things that make Chemex unique. These filters are 20-30% thicker than ordinary coffee filters in order to filter out bitterness and oils from coffee grounds. Also, it is what makes your coffee super clear.

When it comes to using these filters, it might seem hard but it is easy. The folding part is actually easy. Just keep it folded and then open it up so you can get one layer on one side and three layers on the other. The three-layer part is the part where you put against the pour spout on the Chemex.

Which Chemex filter papers should you choose? Square vs circular filters? There is actually no difference between them but the little points on the square one can make it easy to lift up. So you might choose circular filters if you have to make a decision.
