Description
Guzmán Favre and five co-authors develop a sharper method to measure small flavanol compounds in grapes and wines, in a research paper from 2025. These compounds hint at whether tannins came from grape skins or seeds, and at the style of a wine. Standard tests are thrown off by larger tannin molecules.
Their two-step method first removes the large molecules, then measures what remains with a sensitive, specific reagent. A new index expresses the small share relative to the removable tannins. The method proved linear, precise, and accurate in validation. It separated two grape varieties and showed clear differences between skins, seeds, and soaking methods.
