Another study found that the perception threshold of 3-mercapto-3-methylbutan-1-ol is 1500 ng/L. [15] This study found that MMB had a "catty" odor, had an orthonasal odor threshold of 2 μg/L in water, and was found in concentrations from 150-1500 μg/kg in coffee. The synthesis of MMB in wine is brought on by the fermentation process.
