The influence of the winemaking process on the elemental composition of the Marselan red wine.

Background: The elemental profile of the Marselan wine cycle was studied with a single ion-beam technique, namely particle-induced X-ray emission (PIXE). Samples were collected from all of the major stages involved in the wine cycle, including soil, vine plant, grape, and different stages of wine processing.

Results: The results show the influence of field practices on the elemental composition of leaves, branches, grapes, and soil.
