Prepare the Filter

We’ve gathered all the necessary equipment for making great coffee with the Chemex coffeemaker – now it’s time to prepare the filter. Select a thick filter paper, as this will help provide an even extraction and keep finer particles out of your cup.

Place the filter in the Chemex and don’t forget to pre-wet it – why not give it a try? It takes only a few seconds, but helps ensure that your coffee has a balanced flavor. Pre-wetting also helps remove any potential paper taste from the brew.

Once you have chosen and pre-wet your filter, it’s time to move on to grinding those coffee beans!

Grind the Coffee Beans

Grind the Coffee Beans

Now it’s time to get those coffee beans pulverizing – let’s create some deliciousness! Pulverizing the beans is all about finding the right size and consistency for your preferred technique. There are a few different techniques to achieve this:

  • Burr grinders, which use two abrasive surfaces to grind the beans evenly
  • Blade grinders, which chop up the beans with a spinning blade
  • Hand grinders, which manually crush the beans between two burrs

When selecting your beans, consider choosing ones that are freshly roasted and of high quality. The type of bean you choose also affects how you should be grinding them. Darker roasts tend to require a finer grind whereas lighter roasts need coarser grounds.

It’s important to remember that freshness and quality can make all the difference in producing a great cup of coffee. Now we’ve got our grounds ready – let’s add them into our Chemex brewer!

Add the Coffee Grounds

To prepare your coffee maker of choice, add your perfect grind! The Chemex coffeemaker is ideal for pour-over extraction and comes in various sizes. The quantity of ground coffee you require is determined by the volume of water you intend to use.

A general rule of thumb is 2 tablespoons per 8 ounces, but always make sure to adjust according to your taste preference. Before adding the grounds, be sure that the filter is clean and free from any debris.

This will ensure that the flavor profile remains unaffected when making each cup of coffee. After adding the desired amount of ground coffee beans, it’s time move on to pouring hot water over them!

Pour Hot Water

We’re now going to move on to the next step in brewing a delicious cup of coffee with a chemex coffeemaker – pouring hot water.

First, you’ll need to ‘bloom’ your grounds by pouring a small amount of hot water over them and allowing them to steep for 30 seconds. This helps release the oils that give coffee its flavor and aroma.

Next, pour more hot water slowly around the edges of the grounds in concentric circles until all are saturated. Now stir the grounds gently for 10-15 seconds before finishing up with a final pour. Keep adding water until it reaches just below the top of the filter paper.


Before you start making, you’ll need to do a ‘bloom’ – otherwise known as pre-infusion. This step is essential for unlocking and releasing the full potential of your coffee grounds.

Starting off with fresh, hot water helps bring out the complexity of flavor in your coffee from the very beginning. To do this, add just enough water that it will saturate all of the grounds – just enough to make them look wet but not so much that they float on top of the water.

The amount should be about twice as much as your total brew size; for example, if you’re making 16oz total (2 cups), use 32oz of hot water to bloom first.

The ideal temperature for blooming is around 200°F (93°C). You can measure this with an instant read thermometer, but usually it’s best to err on the side of caution and wait until after steaming milk or boiling water before pouring over your grounds.

Moreover, ensure the particle size is large enough that none of them are too fine and clog the filter paper during blooming. A good reference point is somewhere between a French press particle size and drip particle size – slightly finer than what you would use for pour-over coffee but coarser than espresso particle size.

After this initial step has been completed successfully, now comes time for pouring!


Now that the bloom is complete, it’s time to start pouring. When it comes to pouring for a Chemex, we like to think of it as an art form. There are a few key points to consider when pouring:

  • Keep an eye on the levels – Make sure you’re keeping track of the level of liquid in your Chemex throughout the entire pour.
  • Adjust your water temperature – Try to keep a water temperature between 195-205°F (90-96˚C). Cold steeping will take longer and hot steeping can scorch your grounds, resulting in bitter flavors.
  • Create concentric circles – As you pour each round of water into your Chemex, try to create concentric circles within the coffee bed so that all grounds are evenly saturated.

Pouring is one of the most important steps when crafting delicious cups with your Chemex coffeemaker and getting it right takes practice and patience. Now that we’ve finished up with pouring, let’s move on to steeping—the next step in our guide!


After pouring, it’s time to steep the coffee to perfection! Making temperature and grind size are crucial when steeping your Chemex.

For the optimum flavor profile, aim for making temperature of 195-205°F (90-96°C) and a coarse grind size similar to that of Kosher salt. With these parameters set correctly, your grounds will steep evenly and slowly extract all of the delicious flavors from your beans.

Be sure to keep an eye on the clock as you don’t want any bitter notes from over extraction. Once it’s been adequately steeped, it’s time for stirring!


Using a wooden spoon or chopstick, gently stir the grounds twice to ensure an even extraction of flavor. The swirling motion you make is like a peaceful dance, creating beautiful aromas that will tantalize your taste buds.

It’s important to pay attention to dosing ratios and stirring technique; too little stirring can lead to uneven extraction which will affect the brew’s flavor, while too much stirring can cause over-extraction and impart bitter notes.

Moving onto our next step in this process – the final pour.

Final Pour

With a steady hand, your final pour will be the perfect conclusion to this magical coffee-making journey. The pouring process is an art form in and of itself—one where precision and time management are key to flavor extraction.

To achieve the ideal cup of coffee, you must ensure that all water is poured slowly and evenly over the grounds in concentric circles. Your last pour should also create a slight mound in the middle of your filter so that all grounds remain fully saturated throughout brewing.

Time management is essential when it comes to making Chemex coffee; as with most things, timing can make or break a brew. You want to aim for a total brew time between 4-5 minutes after you have finished your final pour.

Once satisfied with your craftsmanship, place the lid on top of the brewer and watch as each drop of hot water filters through into your carafe below. Enjoy!

Brew the coffee

Brew the coffee

The Chemex Coffeemaker is a device that allows you to brew coffee with a paper filter and a kettle. It was invented by Peter Schlumbohm in 1941 and is made of borosilicate glass with a wooden collar and a leather tie.

It can produce some of the best coffee you can make at home, with a clean and balanced flavor. To make coffee with the Chemex, you need to follow these steps:

  1. Boil water in a kettle and let it cool slightly to about 205°F.
  2. Grind your coffee beans to a medium-coarse consistency, about the size of kosher salt.
  3. Fold the Chemex filter and place it in the top of the brewer, with the thick side facing the spout.
  4. Rinse the filter with hot water to remove any paper taste and preheat the brewer. Discard the water.
  5. Add your ground coffee to the filter and shake it gently to level it.
  6. Start your timer and pour enough water to wet all the grounds, about twice the weight of the coffee. This is called the bloom, and it allows the coffee to release gases and expand.
  7. After 30 seconds, pour more water in a circular motion, starting from the center and moving outward. Avoid pouring on the edges of the filter or directly on the spout.
  8. Keep pouring water until you reach your desired amount of coffee, or until the timer reaches 4 minutes. The ideal ratio is about 60 grams of coffee per liter of water.
  9. When all the water has drained through the filter, remove it and discard the grounds.
  10. Enjoy your coffee without any sediment or bitterness.

The Chemex Coffeemaker has a unique shape that helps regulate the temperature and extraction of the coffee. The spout allows air to escape and prevents vacuum formation. The wooden collar protects your hands from the hot glass and adds a touch of elegance to your brew.
