In this research dataset, we summarize for the first time volatile organic compounds (VOCs) emitted in vivo from ripening wine grapes. We studied four cold-hardy cultivars grown in the Midwestern U.S.St. Croix, Frontenac, Marquette, and La Crescent. These cultivars have gained popularity among local growers and winemakers, but still very little is known about their performance compared with

Gold nanoprism/Tollens’ reagent complex as plasmonic

Headspace (HS)-SDME is an appropriate approach for enrichment of volatile compounds since they can be extracted from the sample headspace without any contact between the solvent droplet and the sample [27,28]. Hence, the potential interferences presented by a complex matrix can be fully eliminated.
