Decaf coffee is a type of coffee that has had most of its caffeine removed, making it a popular choice for those who want to enjoy the taste of coffee without the stimulating effects of caffeine. The decaffeination process typically involves using water, organic solvents, or carbon dioxide to extract caffeine from the coffee beans. Despite the reduction in caffeine, decaf coffee still retains many of the flavors and aromas associated with regular coffee. It is often enjoyed by individuals who are sensitive to caffeine or those who prefer to limit their caffeine intake for health reasons, such as insomnia or anxiety.
