Uncertainty of analytical results in oenology laboratories

Abstract

The analytical results (measurements/determinations) concerning the parameters of wine chemical composition and must and wine-based products have shown some uncertainty or doubt. The oenology laboratories must determine the uncertainty of analytical results for each measured parameter, according to the used analysis method, for checking trueness and certainty of the method. In this scientific paper, the authors have shown the uncertainty calculation methodology and the interpretation of uncertainty values according to the analytical results.
