You might have heard of decaffeinated coffee, which has become very popular, especially among caffeine-intolerant people.

Decaf coffee is manufactured by decaffeinating 100% Arabica coffee beans. This process helps remove 97% of the caffeine, so the beverage does not become caffeine-free. Decaf coffee will have around 3 mg of caffeine per cup, which is significantly less when compared to regular coffee.

You can use decaffeination methods like the swiss water process, carbon dioxide, methylene chloride, and ethyl acetate to remove caffeine.

The natural water process removes caffeine by soaking the coffee bean in water and filtering the extract using a carbon filter. This method will help retain most nutrients and remove around 99.9 % of caffeine.

According to the brand of decaf coffee and the decaffeination process, the caffeine content of the beverage will differ.
