John Freeborg asks about acidifying sparge water.

According to Dr. Lewis at UC Davis, water is not a good buffer, ie. water's
ability to alter pH is very weak. In a contest between a mash of 5.0 - 5.5 and
sufficient sparge water at 6.5 - 7.5 the mash will win. Only if your local
water is on the alkaline side should you worry about modifying the pH prior to
sparge. Lewis says that there is no harm in adding lactic acid to sparge water,
especially if it makes you feel better about your beer, however the benefit is
psychological only.
