The Principles of pH

FREE

What (exactly) is pH and what can – or should – a homebrewer do about it? You may not know much about it (and depending on your water and the beers you brew, you may not need to), but pH affects many major aspects of beer character. Learn the simple steps to manage pH in your homebrews.
