The Vancouver Indy Coffee Scene

Coffee with its original caffeine content removed. The decafeination (decaf) process involves immersing the un-roasted coffee beans in a solvent to remove the caffeine. The conventional process involves reusing the decaffeinating solvent again and again, thereby saturating the solvent with coffee flavours and preventing further transfer of flavour from the beans to the solvent. Commonly used solvents include water (see Swiss Water Process), benzene, ethyl acetate, methylene chloride (MC), and carbon dioxide (CO2).

The Swiss Water Process is by far the better process or decafeination, which results in a far better product then any other process delivers.
