I was wondering how coffee is being decaffeinated.
How is this achieved? Are there different approaches? Since when is this practice?

Welcome to [coffee.se]. The other linked question has the answer; if your question is different (e.g., how to decaffeinate at home?) please feel free to ask another or edit this one and we can re-open. – hoc_age Dec 31 '16 at 20:14
