Wine Waste Compost Addition to a Vineyard of Chelva Grape of Central Spain: Effect on Wine Volatile Compounds
The use of winemaking waste compost as an alternative fertilization treatment for vines of the Chelva grape variety was researched. Three different organic amendments (1 kg/m, 2 kg/m, and 3 kg/m) of winemaking waste compost were applied, and a no-applied-amendments condition served as the control. T...

| Summary: | The use of winemaking waste compost as an alternative fertilization treatment for vines of the Chelva grape variety was researched. Three different organic amendments (1 kg/m, 2 kg/m, and 3 kg/m) of winemaking waste compost were applied, and a no-applied-amendments condition served as the control. The wines were elaborated according to a traditional white winemaking process. The solid phase extraction (SPE) technique and gas chromatography coupled to mass spectrometry (GC-MS) techniques were, respectively, used for the isolation of wine volatile compounds and their identification and quantification. A total of 81 aroma compounds were identified and quantified in Chelva wines, independently of the fertilization treatment used. The results bring to light that the application of organic amendments from winemaking waste compost during vine cultivation produced changes in the concentration of wine volatile compounds, especially for the varietal aroma compounds. These results show that the use of wine-distillery compost as a vine fertilization treatment is a viable alternative to traditional fertilization methods, particularly when the fertilization dose is 2 Kg/linear meter. |
