Abstract

This study investigates the influence of 1,1,6-Trimethyl-1,2-Dihydronaphthalene (TDN) on the sensory perception of Chardonnay, focusing on whether TDN alone can lead to a misidentification of Chardonnay as Riesling. By exploring the distinctive olfactory contribution of TDN, typically identified in aged Riesling wines, this research examines its effect when introduced into Chardonnay. Using an automated system, sniff olfactometer which can deliver precise dosages of TDN to the headspace of wine samples with controlled timing. This setup allows for precise measurement of recognition probabilities and dose-response relationships, enhancing our understanding of how TDN's presence influences the perceived organoleptic profile of Chardonnay compared to Riesling under similar vintner and vintage conditions.
