Description

Bruna Paviani and co-authors profile the chemistry of grape pomace, the skins and seeds left after winemaking, from four California varieties in 2026. White wine pomaces from Chardonnay and Sauvignon Blanc held more leftover sugar and wider sugar chain diversity than red pomaces from Pinot Noir and Merlot. Advanced mass spectrometry identified thirty-nine oligosaccharides, built mainly from six carbon and five carbon sugars.

Two flavanol compounds, catechin and its mirror form epicatechin, made up to half of measured phenolics in Chardonnay pomace and about 45 percent in Pinot Noir. Glucose and fructose dominated the sugar building blocks. The molecular map supports turning this winery residue into valuable ingredients.
