TI - 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' AID - 10.5344/ajev.1972.23.3.103 DP - 1972 Jan 01 TA - American Journal of Enology and Viticulture PG - 103--105 VI - 23 IP - 3 4099 - http://www.ajevonline.org/content/23/3/103.short 4100 - http://www.ajevonline.org/content/23/3/103.full SO - Am J Enol Vitic.1972 Jan 01; 23 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.
