What is the process of "decaffeination"?

Decaffeination refers specifically to the process of removing caffeine from coffee beans. This method allows coffee lovers to enjoy the rich flavors and aromas of coffee without the stimulating effects of caffeine. Various techniques can be utilized for decaffeination, including solvent-based methods, water processes, and carbon dioxide methods, each aiming to extract caffeine while preserving the coffee's overall flavor profile as much as possible.

The other options do not accurately define decaffeination. Flavoring coffee without caffeine suggests an addition process rather than the removal of caffeine. Brewing coffee with cold water refers to cold brew techniques and is unrelated to caffeine removal. Fermenting coffee beans may affect their flavor but is not associated with the caffeine content. Thus, the correct definition of decaffeination is focused solely on the removal of caffeine from the beans.
