Decaf, short for decaffeinated coffee, is a type of coffee that has had most of its caffeine removed. The decaffeination process typically involves soaking the coffee beans in water or using solvents to extract caffeine while preserving the flavor. This allows people to enjoy the taste of coffee without the stimulating effects of caffeine. Many people choose decaf for various reasons, including sensitivity to caffeine, health concerns, or the desire to enjoy coffee later in the day without disrupting sleep. Decaf is available in various forms, including ground coffee, whole beans, and coffee pods.
