To review current knowledge on the molecular mechanisms and wine matrix factors that govern red wine astringency perception beyond traditional tannin–protein interactions.
Narrative review synthesizing evidence on the biochemical pathways, oral physiological mechanisms, and sensory sub-qualities of red wine astringency.
Evaluated the modulating effects of non-tannin wine matrix constituents, including anthocyanins, grape polysaccharides, and mannoproteins, on tannin-protein binding and stability.
Identified three distinct mechanisms and two integrated conceptual models that explain astringent tactile mouthfeel, including oral drying, roughening, shrinking, and puckering.
Demonstrated that interactions between tannins, salivary proteins, anthocyanins, polysaccharides, and mannoproteins significantly modulate the stability and conformation of protein complexes, altering sensory sub-qualities.
