Chemex Coffee Maker


The Chemex is perfect for you if you enjoy a clean and refreshing cup of coffee. This coffee maker has been around for over 70 years and is known for its unique paper filter that removes unwanted oils and sediments, resulting in a smooth and flavorful cup of coffee.

In this brewing guide, we'll show you how to make the perfect cup of coffee using a Chemex. We'll take you through each step of the process so you can get the results you want every time. So, grab your Chemex and let's get started!


    Before we start brewing, there are some things we need to prepare.
    • Have a kettle ready with at least 1000 ml of water, a scale and a grinder.
    • We will be setting our kettle for 96℃ degrees.


    Chemex Coffee Maker Step 1 Weigh out 25 grams of coffee and grind it on a medium-coarse setting.
    Chemex Coffee Maker Step 2 Rinse the filter with hot water. Chemex filters are 25% thicker than other options, so LOTS of water is needed. 
    Chemex Coffee Maker Step 3 After removing the water, place the ground coffee into the filter. 
    Chemex Coffee Maker Step 4 Add 75ml of water and let it bloom for 30 seconds. At 30 seconds, use a spoon to agitate the grounds for further saturation.
    Chemex Coffee Maker Step 5 We will slowly add water in a circular motion until the scale reads 400ml for a continuous pour. Your arm will tire, but the coffee will be worth it!
    Chemex Coffee Maker Step 6 Give it a gentle stir around the edges, making a half circle in each direction.
    Chemex Coffee Maker Step 7 When its done draining, you can discard the filter or compost it.
    Chemex Coffee Maker Step 8 Serve it up and enjoy!
