Three p-menthane lactones and menthofuran were identified for the first time in wine.
The concentrations measured in red wine for all the compounds studied were in ng/L.
These lactones contributed actively to freshness, coconut, vanilla, and mint odors.
An enhancing effect of freshness and mint note was perceived when these lactones were blended together.
Blending together these lactones significantly enhanced freshness and mint aroma.
