Wine is a globally traded beverage, and so anything which could adversely affect the quality or the safety of wines has the potential to affect a huge number of people with significant economic consequences. Through effective proficiency testing measures and complementary quality procedures, the quality of the laboratory analysis can be underpinned and help prevent sub-standard product being released to the market
Toxic heavy metals, such as Cadmium, Copper, Lead and Iron are often found in wine, either as a natural contaminant or as a result of contamination from production practices. This uptake of heavy metals is of particularly high risk within wine due to the length of time taken for the grapes to grow and ripen. This, combined with the use of some heavy metal based plant protection products, such as Bordeaux mixture (copper sulphate solution) to control mildew, increases the importance of accurate testing to detect and quantify these potential contaminants within wines.
Fapas proficiency tests can help to highlight potential deficiencies within your testing process, such as bias, possibly due to poor instrument calibration for example. By using real matrices your proficiency test results are comparable to your routine analysis and as such can provide direct improvements from which to safeguard your high-quality testing practices.
