Didn't see anyone talking about using salt with their coffee grounds. I was turned on to this a few years ago and have been using it ever since.
Just put a pinch of Kosher salt in with your coffee grounds prior to brewing, regardless of the method. It will cut the bitterness, and it really brings out the flavor of the beans. Remember though, if you can taste the salt you put too much in.
Yeah, I saw that episode of Modern Family too. Works in cutting the bitterness of poor quality coffee, but also blocks the appreciation of the coffee flavor a little. Not what I am after in a high quality cup.
