How to Brew Coffee with a Chemex: A Step-by-Step Guide

The Chemex is a classic pour-over brewer known for its elegant design and ability to produce a clean, bright cup of coffee. If you've ever wondered how to brew coffee with a Chemex, you're in the right place. This guide will walk you through each step, from choosing the right beans to pouring technique, so you can enjoy café-quality coffee at home.

Whether you're a beginner or looking to refine your pour-over skills, these Chemex brewing steps will help you extract the best flavors from your coffee. We'll also share tips on grind size, water temperature, and ratio, along with comparisons to other pour-over methods.

What You'll Need

Before you start, gather your equipment: a Chemex brewer, Chemex filters, a gooseneck kettle, a scale, a timer, and freshly roasted coffee beans. For the best results, use a burr grinder to achieve a consistent grind size. We recommend a medium-coarse grind, similar to sea salt, for Chemex brewing.

Water quality matters too. Use filtered water, and heat it to about 200°F (93°C) – just off the boil. If you don't have a thermometer, let the kettle sit for 30 seconds after boiling. This temperature range ensures optimal extraction without over-brewing.

• Chemex brewer and filters
• Gooseneck kettle for precise pouring
• Digital scale and timer
• Fresh coffee beans – try our Okoluu – Natural Sundried for a fruity, clean cup

Step-by-Step Brewing Instructions

Start by placing the filter in the Chemex, with the triple-fold side facing the spout. Rinse the filter with hot water to remove any paper taste and preheat the brewer. Discard the rinse water. Next, grind your coffee to a medium-coarse consistency. A good starting ratio is 1:15 – for every gram of coffee, use 15 grams of water. For a 6-cup Chemex, that's about 42 grams of coffee and 630 grams of water.

Add the ground coffee to the filter and gently tap to level it. Start your timer and pour a small amount of water (about twice the weight of the coffee) in a circular motion to saturate the grounds. This is called the bloom. Wait 30 seconds for the coffee to degas. Then, continue pouring in a slow, steady stream, moving outward from the center, until you've added all the water. Aim to finish pouring by 3-4 minutes. Let the water drain completely – the total brew time should be around 4-5 minutes.

• Use a 1:15 coffee-to-water ratio for a balanced cup
• Bloom for 30 seconds to release CO2 and improve extraction
• Pour in a spiral motion to ensure even saturation

Tips for the Perfect Chemex Cup

To get the most out of your Chemex, pay attention to your grind size. If your coffee tastes bitter, try a coarser grind; if it's sour, go finer. Adjusting your grind is the easiest way to dial in your brew. Also, make sure your water is at the right temperature – too hot can over-extract, too cool can under-extract.

The Chemex is known for its thick filters, which produce a very clean cup with no sediment. This also means it can handle a slightly finer grind than other pour-over methods. Experiment with different beans to find your favorite. Our Equilibrium blend offers a smooth, balanced profile, while Finca Santa Elena - Pacamara Honey provides a unique honey-processed sweetness.

• Keep a brewing journal to track your variables
• Preheat your mug or carafe to keep coffee hot longer
• Clean your Chemex thoroughly after each use

Chemex vs. Other Pour-Over Methods

The Chemex is often compared to other pour-over brewers like the V60 or Kalita Wave. The main difference lies in the filter thickness and shape. Chemex filters are thicker, resulting in a cleaner cup with less body, while V60 filters are thinner, allowing more oils and fines to pass through for a richer flavor. The Chemex's larger capacity makes it ideal for brewing multiple cups at once.

If you're looking for a more forgiving pour-over, the Kalita Wave's flat bottom and three-hole design provide a more even extraction. However, the Chemex's elegant design and ability to brew a large batch make it a favorite for entertaining. Whichever you choose, mastering pour-over techniques will elevate your coffee game.

• Chemex: clean, crisp, low body
• V60: complex, aromatic, higher body
• Kalita Wave: balanced, forgiving, medium body

Brewing with a Chemex is a rewarding ritual that produces a remarkably clean and flavorful cup. With these steps and tips, you'll be able to enjoy a perfect pour-over at home. Remember to experiment with different beans and grind settings to find your ideal brew. Happy brewing!
