Learning how to make Chemex coffee is rewarding journey that elevates your coffee experience to new heights. The Chemex’ s thick paper filters remove even the finest particles and most of the oils, resulting in a cup that is crisp, clear, and full of nuanced flavors. Whether you are brewing for yourself or for two, this guide will walk you through every step, from the perfect ratio to the ideal grind size, ensuring you unlock the full potential of this beautiful brewer.
The Basics: Understanding the Chemex
Before diving into the brewing process, it is important to understand what makes the Chemex unique. The Chemex is a pour-over brewer made of non-porous borosilicate glass, which does not absorb odors or chemical residues. Its design allows for precise control over the brewing process, making it a favorite among coffee purists.
For those wondering about the Chemex coffee maker, it is available in several sizes, including the popular 3-cup, 6-cup, and 8-cup models. The 6-cup and 8-cup versions are the most common and are perfect for brewing multiple servings or sharing with a friend.
The Perfect Ratio: Chemex Coffee Ratio Chart
One of the most critical factors in brewing great Chemex coffee is the coffee-to-water ratio. Getting this right ensures that your coffee is neither too weak nor too strong. The Chemex coffee ratio chart is a helpful reference for achieving the perfect balance.
The standard ratio for Chemex is 1:15 to 1:17, meaning one part coffee to 15-17 parts water. For most people, a ratio of 1:16 is the sweet spot. Here is a quick reference:
- For 1 cup (8 oz / 240 ml): 15 grams of coffee to 240 ml of water
- For 2 cups (16 oz / 480 ml): 30 grams of coffee to 480 ml of water
- For 3 cups (24 oz / 720 ml): 45 grams of coffee to 720 ml of water
- For 4 cups (32 oz / 960 ml): 60 grams of coffee to 960 ml of water
This ratio is the foundation for a great cup. However, you can adjust it slightly based on your personal preference. If you prefer a stronger brew, use a ratio of 1:15; for a milder brew, use 1:17.
Mastering the Technique: How to Make Chemex Coffee for One
Brewing for one person can be tricky with a larger Chemex, but it is entirely possible with the right technique. Learning how to make chemex coffee for one ensures that you can enjoy a perfect single cup without wasting coffee or water.
Here is the step-by-step method for a single serving:
Ingredients:
- 22-25 grams of coffee beans (about 3 tablespoons)
- 350-400 ml of water (about 12-14 oz)
- Freshly boiled water (ideally 200°F / 93°C)
Instructions:
- Fold the Filter: Take a Chemex filter and fold it along the seams to create a cone shape. Place it in the top of the Chemex, with the three-layered side facing the spout.
- Rinse the Filter: Pour hot water over the filter to rinse away any paper taste and preheat the Chemex. Discard the rinse water.
- Add the Coffee: Grind your coffee beans to a medium-coarse consistency, similar to sea salt. Add the grounds to the filter and gently shake the Chemex to level the bed.
- Bloom: Pour just enough water (about twice the weight of the coffee) over the grounds to saturate them. Let it sit for 30-45 seconds. This allows the coffee to degas and release its flavors.
- Pour: Slowly pour the remaining water in a circular motion, starting from the center and moving outward. Try to maintain a steady, even flow. Aim to finish the pour within 2-3 minutes.
- Drain: Allow the water to drain completely through the filter. The total brew time should be about 3.5 to 4.5 minutes.
- Serve: Remove the filter, swirl the coffee gently, and pour into your favorite mug. Enjoy your perfectly brewed single cup.
Brewing for Two: How to Make Chemex Coffee for Two
Brewing for two is one of the most common uses for the Chemex, and it is a wonderful way to share the experience with a friend or loved one. Learning how to make chemex coffee for two allows you to double the recipe while maintaining the same quality.
For two cups, use 42-45 grams of coffee and 700-720 ml of water. This will yield about two 12-ounce cups. The brewing process is the same as for a single cup, but you will need to adjust the pour rate to accommodate the larger volume. A slower, more deliberate pour ensures even extraction. The total brew time for two cups is typically 4-5 minutes.
Grind Size: Chemex Coffee Grind
The grind size is crucial for Chemex brewing. The chemex coffee grind should be medium-coarse, similar to the texture of coarse sea salt or raw sugar. This grind size allows for a steady flow of water through the coffee bed, preventing over-extraction (which causes bitterness) or under-extraction (which causes sourness).
If your coffee is too fine, the water will drain too slowly, resulting in a bitter, over-extracted brew. If it is too coarse, the water will drain too quickly, resulting in a weak, under-extracted cup. Investing in a quality burr grinder is highly recommended for achieving a consistent grind size.
Brewing Without a Scale: How to Make Chemex Coffee Without Scale
A common question among beginners is how to make chemex coffee without scale. While a scale provides the most accurate measurements, it is entirely possible to brew a great cup without one.
Here is a rough guide:
- Use 2 tablespoons of whole coffee beans per 6 ounces of water.
- For a 12-ounce cup, use about 4 tablespoons.
- For a 6-cup Chemex (which holds about 48 ounces), use about 16 tablespoons of coffee.
Brewing Guide: How to Brew Chemex 6 Cup
For those who own the popular 6-cup model, learning how to brew chemex 6 cup is essential. The 6-cup Chemex is the most common size and is perfect for brewing 3-4 servings.
To brew a full 6-cup Chemex:
- Use 60-65 grams of coffee (about 8 tablespoons).
- Use 960-1000 ml of water (about 32-34 ounces).
- Follow the same blooming and pouring technique.
- Total brew time should be around 4-5 minutes.
The 6-cup model is versatile and can brew as little as 2 cups or as many as 5 cups, depending on your needs.
