In this study, fourteen samples of Galician Orujo spirit (seven from industrial and seven from homemade sources) were analysed by gas chromatography in order to determine their content in major volatile compounds, methanol, higher alcohols, aldehydes and esters. The main objective of this study was the establishment of the differences existing in the volatile composition of both groups of spirits, to identify the compounds whose presence is due, fundamentally, to the production process, either with reference to the raw material itself or to the latter distillation phase. The variance analysis of the results obtained indicates that, for most of the compounds, there are no significant differences (p
