eli5 How exactly does one “de-caffeinate” coffee? Are they actually removing the chemical?
In: 548
The process is either chemical or by water, which is well explained above, but I will add that the longer a bean roasts, the more of the caffeinated oil seeps out, the less caffeinated it is! So light roasts have more caffeine than dark roasts! Fun little factoid not everyone knows. And yes the caffeine is captured and does go into sodas and other things.
