What Impact Do Under-Extraction and Over-Extraction Have on Coffee Flavor? Grinding Degree and Water-to-Coffee Ratio in Pour-Over Coffee
Extraction: The process of extracting something or obtaining an extract. In chemistry, extraction refers to obtaining valuable substances (flavors) from raw materials (coffee beans). In coffee extraction, hot water is most commonly used to extract flavors from coffee grounds. Over-extraction: Occurs when coffee grounds remain in contact with hot water for too long, resulting in excessive extraction of compounds.
