Understanding the Chemex Brewing Method
Before delving into how to measure coffee for Chemex, let’s take a moment to appreciate what makes this brewing method unique.
A Brief History of Chemex
Chemex was invented in 1941 by Peter Schlumbohm, a German chemist. Its elegant design, made of glass, has made it a staple in both homes and specialty coffee shops. The Chemex employs a vacuum coffee maker method, using specially designed paper filters that are thicker than standard filters. This results in a cleaner cup of coffee with minimal bitter oils, enhancing the coffee’s natural flavor profiles.
Why Precision Matters
Measuring coffee correctly is crucial for several reasons:
- Flavor Balance: The right coffee-to-water ratio ensures that you achieve a balanced flavor profile, avoiding overly bitter or weak coffee.
- Consistency: By measuring your coffee, you can replicate successful brews and avoid trial-and-error, making your coffee experience predictable.
- Extraction Control: Different beans and roasts require different brewing times. A precise measurement helps control the extraction process.
Measuring Coffee for Chemex: The Basics
When it comes to measuring coffee for your Chemex, there are a few key factors to consider: the coffee-to-water ratio, the grind size, and the brewing time. Let’s break these down into manageable sections.
Coffee-to-Water Ratio
The coffee-to-water ratio is the cornerstone of a great brew. A common recommendation for Chemex is to use a ratio of 1:15 to 1:17. This means that for every gram of coffee, you should use 15 to 17 grams of water. Here’s how to choose the right ratio:
- 1:15 Ratio: If you prefer a stronger cup, use 1 part coffee to 15 parts water. This will yield a rich, concentrated flavor.
- 1:17 Ratio: For a more balanced cup, use 1 part coffee to 17 parts water. This ratio produces a smoother, lighter flavor.
Calculating Coffee Amounts
To find out how much coffee and water you need for your desired brew, use this simple formula:
- Total Water (grams) = Coffee Weight (grams) x Chosen Ratio
For instance, if you’re brewing 500 grams of water:
- Using a 1:15 ratio:
Coffee needed = 500 / 15 = approximately 33.3 grams of coffee - Using a 1:17 ratio:
Coffee needed = 500 / 17 = approximately 29.4 grams of coffee
Types of Coffee Grinds
The grind size is also an essential element in achieving the perfect brew with your Chemex. The Chemex typically requires a medium-coarse grind. Here’s a closer look at why the grind matters:
Why Medium-Coarse Grind?
- Water Flow: The medium-coarse grind size allows for sufficient water flow during the brewing process. If the grind is too fine, it may clog the filter and cause brewing issues.
- Extraction Rate: A medium-coarse grind strikes the right balance between allowing for an optimal extraction while preventing over-extraction which can lead to bitterness.
While experimenting, you can adjust your grind size slightly, but the medium-coarse should remain your baseline.
