Check-all-that apply (cata), rate-all-that apply (rata) and napping® as tools for discriminating reductive off-odors in wines
Résumé
Reductive off-odors are amongst the most frequently off-odors found in wines. This defect is caused by Volatile Sulfur Compounds (VSCs). It is not infrequent that VSCs appear during bottle aging most likely if the closure is quite hermetic (1). Therefore, it is paramount to dispose of rapid sensory methods to discriminate among samples with reduction off-odors.
