The methylene chloride (MC) process, also known as the KVW method, is a solvent-based decaffeination technique that gently removes caffeine while preserving flavor. Green coffee seeds are first soaked in hot water to extract caffeine and other soluble compounds. The seeds are separated, and methylene chloride is added to the water to bond with the caffeine molecules. After the caffeine-laden solvent is removed, the seeds are reintroduced to reabsorb their flavor compounds. This process creates a clean, crisp, and complex offering that you we love.
