Query: Really good process

My wife suggested this, and it is great. The coffee is less acidic, and therefore easier on the stomach. It is very smooth,and we do not want to be without it now. We use organic coffee beans, and leave it in the maker for 24 hrs,which makes it higher in caffeine and richer, but not bitter in any way.It comes out just right if the beans are ground coarse,but not the coarsest. (I highly recommend the commercial grinder at your health food store or local coffee house that sells fresh beans.Do NOT use robusto coffee beans, you will not like it, use the Arabica.Starbucks uses a good deal of robusto, and for our taste, it is just too bitter)Follow the directions,you can't go wrong.
