Oversparging, having the pH creep up too high when sparging and having a mash pH too high to begin with can all extract tannins from the grain husks that can give you a grainy flavor. I have had this problem before when using pilsener malts there are 2 ways to fix it at this point:
1. Fine it with PVPP
2. Let it sit another couple weeks at cold temperature, those tannins will eventually settle out.
If that fails, THEN you can dump it, but when in doubt wait a couple weeks.
