Metal components in wine can originate in grapes or the machinery used to make wine. A high iron content can cause clouding due to a lack of solubilization, thus affecting the color and clarity of the wines.

Any iron in the sample reacts with 3-(2-pyridyl)-5,6-bis (4-phenylsulfonic)-1,2,4-triazine (ferrozine) sodium salt in acidic medium and in the presence of a reducing agent. The color increase is directly proportional to the iron concentration of the sample.
