Apr 07, 2020· Statistics Q&A Library 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.
