noun Just like many other aspects of homebrewing, disease pH can be as simple or complex as you want to make it. For those who are having chest pains caused by flashbacks to high school chemistry and perhaps wishing you paid more attention, don’t worry. I didn’t pay attention either. Without getting into too much detail, pH is a 14-point scale that measures the acidity of liquids, specifically the level of hydrogen ions (H+) contained in the liquid. On a pH scale, 7 is neutral (neither an acid or a base). Anything less than 7 is an acid (think lemon juice) and anything more is a base (think baking soda). Like water hardness, pH is a much bigger concern to all-grain brewers versus extract brewers. This is assuming the water used for the extract brew has been deemed suitable for human beings to drink by a competent laboratory. Almost all tap water is fine.
