Ethyl 4-methylvalerate, also known as Ethyl 4-methylpentanoate, is an ester described to have a strong pleasant smell that has been identified in wine and Bavarian pilsner beer. Like other similar alkyl esters, Ethyl 4-methylvalerate is a volatile compound with a fruity smell, and is described to contribute to the powerful fruity and exotic aroma of Capsicum chinense chili pepper which was used as a control in the study of the pungent compounds responsible for the heat and aroma of the Ajies and rocotos Andean chili peppers.
