Research Project: Grape Smoke Exposure Effects: Determining the Compounds that Cause Smoke Impacts in Wine

Location: Horticultural Crops Research

Project Number: 2072-21000-055-005-G
Project Type: Grant

Start Date: Aug 1, 2019
End Date: Oct 31, 2022

Objective:
1. Expose Pinot noir and Chardonnay grapes to isotopically labeled smoke from different smoke sources and make wine. 2. Determine smoke-derived compounds in Pinot noir and Chardonnay grapes and wine that result from smoke exposure from different fire sources.

Approach:
In order to track exactly what comes from smoke and what is found in grapes and wine we propose to expose grapes to smoke that contains diagnostically recognizable reporter groups. This smoke will be generated from barley and will be exposed in specially designed chambers. Grape samples and wines made from grapes exposed to smoke from isotopically labeled barley will be analyzed using nuclear magnetic resonance (NMR) and gas chromatography–mass spectrometry (GCMS).
