Polyphenols in Wine Sensory Properties
Research Guide
What is Polyphenols in Wine Sensory Properties?
Polyphenols in wine sensory properties study the extraction, oxidation, copigmentation, and sensory impacts of anthocyanins, tannins, and flavonols from grapes during fermentation to finished wine.
Anthocyanins contribute to red wine color stability through copigmentation mechanisms (Cheynier et al., 2006, 494 citations). Tannins influence astringency and mouthfeel via protein interactions (Sacchi et al., 2005, 537 citations). Winemaking techniques directly affect phenolic extraction and sensory profiles (Styger et al., 2011, 565 citations). Over 20 papers from 2005-2021 address these processes.
Why It Matters
Polyphenol management during fermentation controls wine color stability, astringency, and aging potential, directly impacting commercial quality (Cheynier et al., 2006). Sacchi et al. (2005) show techniques like maceration time increase tannin extraction for balanced mouthfeel in red wines. Gutiérrez-Escobar et al. (2021) link higher polyphenol content to enhanced sensory scores and market value. These factors guide vineyard practices and winemaking to meet consumer preferences for stable, flavorful wines.
Key Research Challenges
Predicting Oxidation Effects
Polyphenol oxidation during fermentation alters color and aroma unpredictably. Cheynier et al. (2006) detail anthocyanin-tannin reactions forming stable pigments but note variable outcomes. Environmental factors complicate modeling (Teixeira et al., 2013).
Quantifying Astringency Mechanisms
Tannin-protein interactions cause variable astringency perceptions. Sacchi et al. (2005) review extraction methods but highlight measurement inconsistencies. Styger et al. (2011) emphasize sensory synergies needing better metrics.
Climate Impact on Extraction
Drought alters berry phenolics, affecting sensory properties. Teixeira et al. (2013, 422 citations) and Savoi et al. (2016) show modulated phenylpropanoid pathways reduce anthocyanins. Adaptation strategies remain underdeveloped.
