No flavor unless you use a LOT! The main purpose is to reduce the pH of the water in the mash. Secondarily, it can be used to adjust the pH and mineral content of the boil to accentuate hopiness.

It accentuates bitterness more than hopiness to me, atleast by my definition. Hopiness to me means flavor and aroma and not necessarily bitterness. I was using gypsum in some of my lighter ales (creamale, kolsch, etc.) to reduce the pH of my mash and was getting nailed in competitions for having a lingering bitterness. I switched to CaCl to lower the pH and the bitterness pretty much disapeared.

Thanks for keeping me honest, Pacman. I agree, I should have said bitterness.
