While well-accepted when in balance with other aged characteristics for their contribution to complexity, such aromas are considered undesirable in young Riesling wines. This following article highlights possible targets in the grapegrowing and winemaking process to tackle the problem of excessive petrol aroma by reducing the potential of 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN) - the marker molecule associated with this aromatic expression.Read less <
