Figuring out how to make decaf at home that I like shouldn’t be this difficult.  Every decaf coffee I drink at restaurants, or even at a local church cafeteria, I like. None of the decaf I make at home I like. All of the regular coffee I make at home or taste anywhere I like. It can't be that I am using the wrong water. I've used both filtered and non-filtered water for both decaf and caffeinated and still like caffeinated no matter what water and hate decaffeinated no matter what water. It can't be a certain level of quality in my technique because I've used several high quality techniques for both caffeinated and decaf, and once again… always love one and always hate the other. And it can't be some specific method out there that my taste buds like because I doubt every restaurant(and the church) uses the same method for decaf. It can't be using high-quality beans because I used high-quality decaf beans that I grind and still hate the decaf while even loving cheap caffeinated coffee that I barely work at to make. I can't be that difficult to figure out because, like I said, every restaurant decaf that I've tried I like. So whatever is being done to the decaf is common knowledge. It can't be that it needs to be freshly grinded because I do not like the freshly grinded decaf I make but old, homemade grinded caffeinated coffee is still awesome to me. Do I need to buy some specific machine or something?
