Wine characteristics: astringency (tasting and tests), classical parameters, polyphenols (focused on tannins), oligosaccharides and polysaccharides

The aim was to find a fast method to estimate red wines astringencies. The datasets contains the following parameters measured for 21 wines: astringencies assessed by sensory analysis or by specific tests such as BSA and MC; classical wine analysis; polyphenols analysis focused on tannins; oligosaccharides; polysaccharides (RGII, mannoproteins, polysaccharides rich in arabinose and galactose); and the absorbances at two wavelengths: 230 and 280 nm.
