I'm surprised nobody has mentioned anything about "cold brewed" coffee.
Wow, that is yummy coffee . . . . not a trace of bitterness, tastes more like hot chochlate rather than coffee, I use only a fraction of the sugar in coffee when I cold-brew it compared to when I hot-brew it. Unfortunately, it takes 2-3 times more grind for the same amount of beverage, so it's much more expensive to do this way. And a little messier as well.

That may be because you are the only person in the world who does that:)
I heard that is GREAT for people that are sensitive to the acid in normally brewed coffee. I have yet to try it.
