I use the Melita single cup method. My sister got me the plastic Melita cone that you set on your favorite cup. I do not use their special cone filters due to price and varying quality. I found the Mr. Coffee type filters work just fine and I can buy them in larger quantity way cheap.
I grind my own beans with a simply blade type bean grinder...again cheap. I have learned to grind for drip coffee by trial and error.A half second over or under grind makes a difference in the flavor. I am not real picky but the right size coffee particle makes a rockin cup of joe.
I buy whole beans that I can see. I like a nice light brown medium roast.I care that the beans are fresh and not greasy in appearance. I have found a (again cheap) blend that they sell
a lot of tends be more freshly roasted and is around seven dollars a pound. I have spent way more on exotic beans and so on and the plain truth is for me I am having a quality flavor that rivals most of them.
Also the single cup method cuts down on the brewing acidity that somehow I don't know why happens with the Mr. Coffee system.
