The reactions this post is getting are kind of odd. A typical home coffee brewing setup is going to offer you just a couple of variables --- a set-it-and-forget-it grind size, water temperature, and the dose of grounds you use for whatever amount of coffee you brew.
It is not especially weird or "gourmet" to be interested in what the right values are for each of those variables. You figure out the right grind size and dial it into your grinder; you figure out the right temperature and hit that button on your kettle; you figure out the right dose and either weigh or scoop-measure that much grounds. Mostly what I'm describing is the simple act of brewing a cup of coffee.
