What does the process of coffee extraction involve?

The process of coffee extraction involves dissolving soluble compounds from coffee grounds in water. This process is critical as it is how the flavors, aromas, and other desirable compounds from the coffee beans are extracted to create the beverage we enjoy. When water comes into contact with the coffee grounds, it penetrates the cells and releases the oils, acids, and other soluble materials that contribute to the coffee's flavor profile.

The temperature of the water, the grind size of the coffee, and the extraction time all play essential roles in determining how successfully these compounds are extracted, ultimately affecting the taste and quality of the coffee. This method distinguishes coffee brewing from processes that do not involve water, and it emphasizes the importance of the chemical interaction between water and coffee during brewing.
