I made what was supposed to be a Blind Pig clone, but ended up fermenting in the low 50's due to a cold snap, and we didn't account for the ibu loss due to hop bags... so we ended up with something closer to a Cal Common. Boiled up an ounce or so of EKG in a few quarts of water for 20 min and added straight back to the fermenter, definitely added the hop flavor and aroma that we were looking for, haven't noticed any off-flavors as of yet, though unless you add a little dme or sugar, yeah, you'll be diluting your wort a bit. But I would absolutely say this is a nice way to add some fresh hop flavor to an aged brew.
