Simple and inexpensive methodologies for quantifying the total Cu concentration as well as various Cu fractions in wine have been recently developed, including the application of colorimetric analysis, and/or diatomaceous earth depth filtration. Compared to other conventional Cu analysis methods, the proposed approaches are more suitable for winery laboratories for reliable and affordable quantification of total Cu and its fractions during wine production.
