Grind matters! I buy the House Blend at Olympic Roasters locally and always ask to have it ground for a cone filter. Three slightly heaping scoops makes for a just right pot of coffee. The other day the gal didn't set the grinder correctly, and I brought home coffee that is more coarsely ground. And it came out very weak. Ick! Had to increase to four scoops and still not strong enough. So this morning I used five slightly heaping scoops; it should be ready in a moment. Of course this way I will use up the coffee faster and have to buy more, so I guess it is good for business, but kinda' expensive for me.
