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]
