EXTRACTION AND RETENTION OF TANNINS IN RED HYBRID WINE PRODUCTION
tannin extraction in common red wine processing methods and retention post-fermentation a series of hybrid grape fermentations were performed In 2011 the phenolic profiles of must and wine from Maréchal Foch Corot noir Marquette were characterized via and solid-phase extraction (SPE) and highperformance liquid chromatography (HPLC) to |
Why are tannins extracted from grape seeds faster than ethanol?
Ethanol produced by yeasts during alcoholic fermentation from grape sugars lead to a reorganization and solubilization of the grape seed lipids, which favor the extraction of tannins from seeds. This latter extraction takes more time and is slower than the extraction of tannins from skins due to the physical structure of seeds [ 65 ].
Does red wine astringency affect tannin concentration?
The astringency/drying perception of red wine is strongly and positively correlated with the tannin concentration [ 5, 6 ]. Condensed tannins are oligomer and polymer of flavan-3-ols, which are extracted from grape skins and seeds during alcoholic fermentation and extended maceration in red wine making [ 7 ].
What factors contribute to tannin extraction & retention?
Some chemical and physical factors contribute to the extraction of tannins, including pH, ethanol concentration, and temperature. Researchers have also examined the physical or chemical removal of CWM and proteins, in order to enhance tannin extraction and retention in both V. vinifera and hybrid cultivars.
