Beer, is a very complex beverage that contains about 800 organic compounds, although many of these are present in such low amounts that they may have a negligible influence on taste and smell perception.^[1] Most of these compounds were either present in the raw materials (malt, hops and water), or they are by-products of yeast metabolism during the fermentation.

The role of inorganic ion is complicated by numerous factors including interactions between the ratio of the various ions, the multiple ionic species that may be present, the pH of the wort, the effects of chelation or binding on bioavailability, the sugar profile and concentration of the wort, etc.^[2] When presenting recommendations, it's not as simple as saying "you need ___ amount of ___ ion in order to achieve ___ effect."
