Decaffeinated
For many people coffee is something to be enjoyed. However, not everyone can tolerate caffeine, which is responsible for its stimulatory effect. Every coffee bean contains between 0.8 and 4.0% caffeine. The residual caffeine contents of decaffeinated coffee must not exceed 0.1%. There are various ways of releasing the caffeine from the bean. We offer you raw coffee treated by two different processes of decaffeination:

Conventional
The beans are first pre-treated with water vapour. The caffeine is then physically extracted from the bean using an extracting agent. The extracting agent becomes loaded with caffeine to saturation point. The caffeine is then released from the agent, which can start the cycle again in order to absorb more caffeine. This cycle continues until there is virtually no caffeine left in the bean. Finally the bean is redried and can then be roasted as normal.
This is the most commonly used method worldwide.

Water-decaffeinated

The beans are treated with hot water until the caffeine and other constituents are released from them. The water is then filtered. Decaffeinated water is left behind with the soluble components of the coffee beans. The washed beans are then resaturated with this water and dried. This is a very costly process and is still only used rarely today.
