This is a Grade 1 Mandheling Swiss Water Process decaf coffee from Sumatra. The Swiss Water® Process uses pure green coffee extract and proprietary carbon technology to remove caffeine from green coffee beans. Swiss Water® has specified the pore size of the carbon to match the caffeine molecule to ensure only the caffeine is trapped when the caffeine is captured from the green coffee extract. The Swiss Water® Process is certified organic and 100% chemical free. In addition, they are also certified Kosher by the Kosher Overseers Association.
