1,1,6-Trimethyl-1,2-dihydronaphthalene (TDN) is an aroma compound responsible for the kerosene/petrol notes in Riesling wines. In the current article, three sensory thresholds for TDN were determined in young Riesling wine: (about 4 µg/L), (10-12 µg/L), and (71-82 µg/L). It was demonstrated that an elevated content of free SO in wine may have a certain masking effect on the TDN aroma perception. In addition, the influence of wine serving temperature on the recognition of kerosene/petrol notes was studied. It was found, that a lower wine serving temperature (about 11 °C) facilitated identification of the TDN aroma compared to the same wine samples at room temperature.
1,1,6-三甲基-1,2-二氢萘（TDN）是一种香气化合物，赋予雷司令葡萄酒煤油/汽油味。在本文中，测定了年轻雷司令葡萄酒中TDN的三个感官阈值：（约4微克/升）、（10 - 12微克/升）和（71 - 82微克/升）。结果表明，葡萄酒中游离二氧化硫含量升高可能对TDN香气感知有一定的掩盖作用。此外，研究了葡萄酒侍酒温度对煤油/汽油味识别的影响。结果发现，与室温下的相同葡萄酒样品相比，较低的侍酒温度（约11℃）有助于识别TDN香气。
