Resources Stacked Sulfur compounds cause "off odors" in wine, so winemakers want to know the odor threshold - the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine (ug/L). The untrained noses of consumers may be less sensitive, however. The DMS odor thresholds for 10 untrained students are given. DMS odor thresholds 30 30 42 35 22 33 31 29 19 23 Click to download the data in your preferred format.
