This study characterized the peptidomicprofile of sparkling wines after <em>in vitro</em> gastrointestinaldigestion, focusing on molecular composition, structural features,and statistically supported functional predictions. A total of 6,463unique peptides were identified, with 1,662 shared among samples,indicating a highly conserved digestion-derived peptide profile. Theidentified peptide profile was dominated by short sequences (5–15residues), consistent with extensive proteolysis. Amino acid distributionrevealed a recurring compositional pattern enriched in glycine andproline, while the exclusive occurrence of arginine and lysine atthe C-terminus reflected the specificity of enzymatic cleavage duringdigestion. Multivariate modeling (α = 0.05) showed that peptidelength, isoelectric point, aliphatic index, and Boman index significantlyexplained hydrophobicity (GRAVY) variability (R<sup>2</sup> = 0.769),supporting the existence of a structurally organized peptide populationrather than random degradation products. Computational screening indicateda high frequency of predicted functional motifs, including subsetsassociated with antiangiogenic, anti-inflammatory, and quorum sensingmodulation probabilities. The evaluated sparkling wines convergedtoward a similar digestion-derived molecular profile, suggesting thatcommon protein sources and proteolytic mechanisms may govern peptideformation under the experimental conditions employed. This apparentconvergence should be interpreted cautiously, as confirmation willrequire a larger number of samples encompassing a broader diversityof sparkling wine production methods.
