"French press lends to a tepid 'muddy' cup"
It's tepid if you wait too long to drink it..
It's muddy if you grind too fine..........
You've actually brought up some very good points here since a lot of us love FP coffee. The "book" calls for at least 4 minutes of steeping which sometimes can cause the heated water to start cooling off too soon. I use a kettle that heats the water til it boils.... not sure what temp it is but it's hot enough. What we don't want to have happen is that the water is so hot it actually ruins the taste of the coffee and water can be heated to around 212 degrees before it turns into steam. I like hot but that's just ridiculously hot to even think that coffee at 200 degrees is going to be tasty.
4 minutes is not going to let your coffee become tepid and as far as it being "muddy" that only happens if your grind is set too fine. A good FP will keep your grinds minimal and your filter needs to be very fine...I actually have a filter I put over my cup and pour my FP coffee through and there is just the slightest bit of residue left.
The "fine art" of FP'ing is just experience and time to know how to make the perfect cup for you....stir the course grinds with a wood stick and let it mingle and then put the filter over it and let steep for a good 4 minutes and voila'....you have yourself the best tasting coffee. Your own tastes will guide you as far as how much course grounds to use.
