RT Journal Article SR Electronic T1 Identification of 4-Hydroxy-3-Methyloctanoic Acid Gamma-Lactone [5-Butyl-4-Methyldihydro-2-(3H)-Furanone] as a Volatile Component of Oak-Wood-Aged Wines of Vitis Vinifera Var. `Cabernet Sauvignon' JF American Journal of Enology and Viticulture JO Am J Enol Vitic.

Muller YR 1972 UL http://www.ajevonline.org/content/23/3/103.abstract AB A trans isomer of 4-hydroxy-3-methyloctanoic acid gamma-lactone (II A or II B) was positively identified as a component of Cabernet Sauvignon wines by gas chromatographic retention times, infrared spectra, mass spectra, and nuclear magnetic resonance spectra. The lactone is most likely extracted from the oak wood of the container during ageing.
