Abstract (EN): 1,3-Dimethoxybenzene was identified by GC-O, GC-MS and Kovats indices (polar Supel-cowax, 1709; non-polar Rtx-5MS, 1158) as a new volatile component of port wine. Sensory evaluation described this compound as having a sweet medicinal odour with hazelnut, resinous and woody notes. Respective threshold limits in model wine and port wine were 21 and 47 mug l(-1). Quantitative analysis by GC-MS, using a selected characteristic ion (m/z 138), indicated that young port wines from the 1998 vintage contained up to 3 mug l(-1) whereas ports from the 1999 vintage contained up to 20 mug l(-1).
