Mastering the Art of Chemex Coffee Brewing: A Comprehensive Guide

The Chemex, a visually striking and aesthetically pleasing coffee maker, has captivated coffee enthusiasts for decades. Its distinctive carafe, elegant design, and ability to produce a clean, smooth cup of coffee have earned it a reputation as a symbol of refined coffee ritual. While the Chemex may appear intimidating at first glance, its brewing process is surprisingly straightforward, offering a satisfying combination of simplicity and elegance.

 

 

Essential Tools for Chemex Brewing

Before embarking on your Chemex brewing journey, ensure you have the following essential tools:

1. Chemex Carafe:

The iconic carafe, available in various sizes, serves as the vessel for brewing and serving your coffee.

2. Chemex Filters:

These specialized filters, made from unbleached paper, allow for even extraction and produce a clean, clear cup of coffee.

3. Grinder:

A consistent grind size is crucial for optimal brewing. Use a grinder that produces a medium-fine grind, similar to kosher salt.

4. Digital Scale:

Accurately measuring both coffee and water is essential for achieving the ideal flavour balance.

5. Hot Water Kettle:

Bring water to a boil and then let it cool slightly to around 96°C (205°F), the optimal temperature for Chemex brewing.

6. Timer:

Track the brewing time to ensure the coffee extracts properly.

7. Stir Stick:

Gentle stirring aids in even extraction.

 

 

Brewing Process: A Step-by-Step Guide

1. Preheat the Carafe:

Rinse the Chemex carafe with hot water to warm it and remove any papery taste.

2. Grind the Coffee:

Weigh 42 grams (6 tablespoons) of coffee beans and grind them to a medium-fine consistency.

3. Position the Filter:

Place a Chemex filter in the carafe and carefully pour hot water over it to rinse and remove any papery taste. Discard the rinse water.

4. Add Coffee:

Center the ground coffee in the filter and level it evenly.

5. Bloom Phase:

Start the timer and gently pour 60 grams of hot water over the coffee grounds. This initial "bloom" phase allows the coffee to expand and release carbon dioxide.

6. Pouring Stages:

After 30-45 seconds, gradually pour the remaining water in three stages, each time waiting for the water to drain almost completely before adding more.

7. Total Brew Time:

The total brewing time should be around 3.5-4.5 minutes.

8. Enjoy:

Carefully remove the filter with the used grounds and discard them. Pour the freshly brewed coffee into your favourite mug and savour the rich, flavorful cup.

 

 

Tips for Elevated Chemex Brewing

1. Choose Fresh Coffee:

Use freshly roasted and high-quality coffee beans for the best flavour.

2. Experiment with Grind Size:

Adjust the grind size slightly to fine-tune the extraction and bitterness balance.

3. Control Water Temperature:

Maintain the water temperature between 93-96°C (200-205°F) for optimal extraction.

4. Maintain a Consistent Pouring Technique:

Pour gently and evenly to avoid disturbing the coffee grounds.

5. Adjust Brew Time:

Adjust the brew time based on your preference for stronger or weaker coffee.

6. Clean and Dry the Carafe:

After each use, thoroughly clean the carafe to prevent any lingering flavours or odours.
