Critical assessment of chemometric models employed for varietal authentication of wine based on UHPLC-HRMS data

The use of metabolic fingerprinting combined with advanced chemometric tools for wine authentication has increased in recent years. Although numerous studies, showing different authentication strategies, have been published, rarely any attention has been paid to the stability of used classification models over a longer time period.

This study presents a reliable and robust metabolic fingerprinting-based multiclass strategy for varietal authentication of wine.
