Abstract
This work proposes one method of quantifying the principal volatile compounds in oak wood using the direct thermal desorption (DTD) technique coupled with GC/MS. These compounds have a particular sensory importance in wines aged in oak wood barrels: furfural, trans and cis-b-methyl-g-octalactones, eugenol, vanillin and syringaldehyde. The described method requires practically no sample handling and is precise and sensitive.


Key words: direct thermal desorption / volatile compounds / oak wood / wine ageing.
