Experimental design for wine analysis. A total of 26 experimental wines were made by using 22 grape varieties. For each experimental wine, two fermentation replicates were prepared (A and B), giving a total of 52 experimental wines. Wine samples were analyzed by FT-IR (wine as-is) and 1H-NMR spectroscopy (wine as-is and dried wines). Samples for NMR and IR analysis were prepared in duplicates (R1 and R2).
