1,1,6-Trimethyl-1,2-dihydronaphthalene (TDN) is an aroma compound present in wine,[1] particularly aged Rieslings.[2][3] Chemically, it is classified as a 13C-norisoprenoid, as it has thirteen carbon atoms, and is derived from an isoprenoid by the loss of methylene groups.[4]

In wines, TDN is generally considered to contribute to a desirable aroma in low concentrations, but an undesirable aroma in higher concentrations.[5] The aroma is commonly described as a petrol note or by the French term goût de pétrole.[6]

TDN is believed to be a degradation product of β-carotene and lutein.[4] TDN can also by synthesized in the laboratory from either of the ionones, α-ionone or β-ionone.[1]
