Part 3: Direct Solvent Process
The biggest challenge in decaffeinating coffee is removing the caffeine without a loss in resulting flavor. It’s very easy to accidentally take out the oils, sugars, and proteins found in a coffee bean along with the caffeine, if one is only using water. The solvents target the caffeine, while leaving behind the flavor molecules which lead to a bold and distinct decaffeinated cup of coffee.
Part 2: Indirect Solvent Process
Some decaffeinating processes use a “decaffeinating agent” or “solvent” such as ethyl acetate, or methylene chloride at one stage in the decaffeinating process. (Don’t worry-- these agents are completely removed from the green coffee beans, and in some cases, they never even touch the beans themselves...
Washed coffees taste clean and vibrant. The most common method of processing coffee, the washed process provides the most opportunity for consistency and control. If you are looking for a pure coffee taste without added flavor notes from external “impurities”, the best coffee to drink is a wet-processed coffee.
