Decaf Coffee Blend
Decaffeination is the act of removing caffeine from coffee beans. The process is usually performed on unroasted (green) beans, and starts with steaming of the beans. 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. Coffee contains over 400 chemicals important to the taste and aroma of the final drink and it proves a challenge to remove only caffeine while leaving the other chemicals at their original concentrations.
Flavour and aroma are more often than not, impacted by this.
