The Chemex coffee maker has been a staple in the coffee world for decades, known for its unique hourglass shape and ability to produce a clean and balanced cup of coffee. However, achieving the perfect brew with a Chemex requires more than just a good coffee maker – it also requires a deep understanding of the golden ratio. In this article, we’ll delve into the world of Chemex coffee and explore the golden ratio, its importance, and how to use it to unlock the perfect brew.
What is the Golden Ratio?
The golden ratio, also known as the golden mean or phi, is a mathematical constant that has been observed in nature and art for centuries. It is an irrational number, approximately equal to 1.61803398875, and is believed to possess unique properties that make it aesthetically pleasing and harmonious. In the context of coffee, the golden ratio refers to the ideal ratio of coffee to water.
The Importance of the Golden Ratio in Coffee
The golden ratio is essential in coffee because it allows for the optimal extraction of flavors and oils from the coffee beans. When the ratio of coffee to water is too high or too low, the resulting brew can be unbalanced and lacking in flavor. A ratio that is too high can result in a bitter and over-extracted brew, while a ratio that is too low can result in a weak and under-extracted brew.
How to Calculate the Golden Ratio for Chemex Coffee
Calculating the golden ratio for Chemex coffee is relatively simple. The general rule of thumb is to use 1 gram of coffee for every 15-17 grams of water. This means that for a standard 6-cup Chemex, you would use approximately 30-40 grams of coffee. However, this ratio can be adjusted to suit your personal taste preferences.
| Coffee-to-Water Ratio | Chemex Size | Coffee Weight (grams) | Water Weight (grams) |
|---|---|---|---|
| 1:15 | 6-cup | 30 | 450 |
| 1:16 | 6-cup | 28 | 448 |
| 1:17 | 6-cup | 26 | 442 |
Factors that Affect the Golden Ratio
While the golden ratio provides a general guideline for brewing coffee, there are several factors that can affect the ideal ratio. These include:
Coffee Bean Origin and Type
Different coffee beans have unique flavor profiles and densities, which can affect the ideal coffee-to-water ratio. For example, African coffee beans tend to be more dense and require a slightly higher ratio, while South American coffee beans are often less dense and require a slightly lower ratio.
Grind Size and Distribution
The grind size and distribution of the coffee can also affect the ideal ratio. A burr grinder is recommended for Chemex coffee, as it produces a consistent grind size and distribution. A grind that is too fine can result in over-extraction, while a grind that is too coarse can result in under-extraction.
Water Temperature
The temperature of the water can also affect the ideal ratio. Water that is too hot can result in over-extraction, while water that is too cold can result in under-extraction. The ideal water temperature for brewing coffee is between 195°F and 205°F.
