Nope! Decaf undergoes the Swiss Water decaffeination process, which doesn’t use any artificial chemicals at all, just water.
Sure it does, but not different as in bad, just different. Decaffeinating coffee is a difficult process, that puts the coffee bean through the ringer. There’s no way to decaffeinate coffee and have it taste exactly the same as it did while it was caffeinated. However, the processes that our roasters utilize help retain as much of the original flavor profile as possible!
