摘要：

The Txakoli is a wine from the north of Spain with acid characteristics and medium ethanol content. We report the comparative results obtained from red Txakoli elaborated with different grape varieties. We have used chromatographic methods for the characterization of this wine. The volatile compounds were analyzed by means of gas chromatography and the organic acid content was determined by a newly validated liquid chromatographic procedure. The aim of this study is to characterize the red Txakoli and to know the major differences between Hondarrabi Beltza grape variety and the other varieties, Hondarrabi Beltza grape variety is the one which was awarded the Generic Label. The major differences observed in the samples obtained from Hondarrabi Beltza variety are their higher contents in ethanol, propanol, ethyl acetate and tartaric and malic acids.
