Wine experts, oenologists, have determined the odor threshold, the lowest concentration of a compound that the human nose can detect. For example, the odor threshold for dimethyl sulfide (DMS) is given in the oenology literature as 25 micrograms per liter of wine. Untrained noses may be less sensitive, however. You suspect that the mean odor threshold for beginning students is higher than the published threshold Χ=25.
