Continuous-Range States and Observationselping to describe the wine aroma profile (fruity, floral, green/fresh, sweet, spicy, fatty, and other odors). The total intensities for every aromatic series can be calculated as the sum of the OAV of each compound assigned to this series.

Markov Chains in Brownian Motionrsions or open software and web-based platforms (Topspin, Chenomx, and Colmar). Additionally, a simple protocol for 1D .H NMR was included as a starting point and beginner guide to NMR analysis of wine.

Continuous-Range States and Observationsethodologies to apply in the wine industry is still challenging. Thus, the most used HPLC derivatisation methods to determine biogenic amines are presented, but also a simple dispersive solid-phase extraction clean-up/concentration method for selective and sensitive quantitation of biogenic amines in wines using benzoyl chloride derivatisation.
