Espresso shots have never tasted so good.
In the case of coffee, various methods can be used to produce a decaf coffee bean. The process is usually performed on unroasted (green) coffee beans, and starts with steaming of the beans.
When a chemical process is used (Coffee Bean Shop does not use a chemical process), they are then rinsed with a solvent that extracts the caffeine while leaving the other essential chemicals in the coffee beans. The process is repeated anywhere from 8 to 12 times until it meets either the international standard of having removed 97% of the caffeine in the beans or the EU standard of having the beans 99.9% caffeine-free by mass. Coffee contains over 400 chemicals important to the taste and aroma of the final drink: It is, therefore, challenging to remove only caffeine while leaving the other chemicals at their original concentrations.
