* '''Salt additives''' - Brewers may use brewing salts that contain potassium, not to increase the potassium level, but rather to increase the anionic component (e.g. using [[potassium chloride]] to increase the [[chloride]] level). | * '''Salt additives''' - Brewers may use brewing salts that contain potassium, not to increase the potassium level, but rather to increase the anionic component (e.g. using [[potassium chloride]] to increase the [[chloride]] level). | ||
