Understanding Chemex
Chemex is a pour-over coffee maker that was invented in 1941 by a chemist named Peter Schlumbohm. It has a unique hourglass shape, made of non-porous borosilicate glass and wood, which makes it an attractive and functional piece of equipment for coffee enthusiasts.
The Chemex brewing process involves pouring hot water over coffee grounds placed in a cone-shaped filter. The water then flows through the filter and extracts the flavors and aromas of the coffee, producing a clean and crisp cup of coffee.
To get the best results from a Chemex, it is important to use the right grind size. The ideal grind size for Chemex coffee is medium-coarse, which is similar to sea salt. This particle size allows for balanced extraction of flavor by allowing hot water to move freely through the coffee bean grinds.
Using a too-fine grind size can result in over-extraction, which can make the coffee taste bitter. Conversely, a too-coarse grind size can result in under-extraction, which can make the coffee taste weak and watery. Therefore, it is essential to use the right grind size to achieve a perfect cup of coffee with Chemex.
What Is Coffee Grind
Grinding coffee beans is an essential step in the coffee brewing process. The coffee grind refers to the size of the coffee particles after they have been ground. The size of the coffee grind affects the flavor and strength of the coffee. In general, the finer the grind, the stronger the coffee will be.
Coffee grinders come in different types, including blade grinders and burr grinders. Blade grinders chop the coffee beans into small pieces, while burr grinders crush the beans between two burrs to produce a more consistent grind. Burr grinders are generally considered to be the better option for coffee brewing, as they produce a more uniform grind.
The coffee grind size is usually described using a scale that ranges from extra coarse to extra fine. The grind size is important because it affects the rate at which water flows through the coffee grounds during brewing. If the grind is too fine, water will flow through too slowly, resulting in over-extracted and bitter coffee. If the grind is too coarse, water will flow through too quickly, resulting in under-extracted and weak coffee.
In conclusion, the coffee grind is an important factor in determining the quality of your coffee. The grind size affects the strength and flavor of your coffee, so it is important to choose the right grind size for your brewing method. Burr grinders are generally considered to be the better option for coffee brewing, as they produce a more uniform grind.
Importance of Coffee Grind Size for Chemex
Choosing the right coffee grind size is crucial when brewing with a Chemex. The Chemex coffee maker is designed to extract the best flavors from coffee beans, and the grind size plays a significant role in achieving that goal.
The grind size affects the rate of extraction, which is the process of dissolving the coffee compounds in water. If the grind size is too fine, the water will extract too much from the coffee, resulting in a bitter and over-extracted brew. Conversely, if the grind size is too coarse, the water will not extract enough from the coffee, resulting in a weak and under-extracted brew.
To get the best results with a Chemex, you should aim for a medium-coarse grind size. This grind size has a texture like coarse sand and is similar to sea salt. It should feel gritty when rubbed between your fingers but be relatively large and easy to pick up.
Using the right grind size will help you achieve a balanced and flavorful cup of coffee. It will also ensure that the coffee is not over-extracted or under-extracted. The Chemex uses a coffee to water ratio of 1:16, which means that for every gram of coffee, you should use 16 grams of water.
To make coffee for two people, you will need 24 grams of medium-coarse ground coffee and 385 grams of water heated to a temperature of 195°- 205° F. Using a kitchen scale to measure the coffee and water will help you get the perfect ratio and ensure consistency in your brews.
In summary, the importance of choosing the right coffee grind size for Chemex cannot be overstated. It affects the rate of extraction, which in turn affects the flavor and strength of the coffee. By using a medium-coarse grind size and measuring the coffee and water accurately, you can achieve a balanced and flavorful cup of coffee every time.
