Accumulation of volatile oak compounds in a model wine stored in American and Limousin oak barrels
Australian Journal of Grape and Wine Research, 1998 Changes in concentration of oak-derived volatile compounds extracted into a model wine stored in four American and four Limousin oak barrels were measured over a 93-week period. The accumulation curves for cis- and trans-oak lactone and eugenol were asymptotic and virtually identical in shape. Guaiacol was extracted more rapidly in the first six weeks,

Irreversible impacts of heat on the emissions of monoterpenes, sesquiterpenes, phenolic BVOC and green leaf volatiles from several tree species [PDF]
Biogeosciences, 2012 Climate change will induce extended heat waves to parts of the vegetation more frequently. High temperatures may act as stress (thermal stress) on plants changing emissions of biogenic volatile organic compounds (BVOCs).

The impact of ultrasound, micro-oxygenation and oak wood type on the phenolic and volatile composition of a Tempranillo red wine [PDF]
, 2022 The accelerated ageing of a Tempranillo red wine has been studied at pilot scale through the combined application of ultrasound, micro-oxygenation and different oak wood type chips (American, French and Spanish).

Monoterpene and sesquiterpene emissions from Quercus coccifera exhibit interacting responses to light and temperature [PDF]
Biogeosciences, 2011 Light and temperature are known to be the most important environmental factors controlling biogenic volatile organic compound (BVOC) emissions from plants, but little is known about their interdependencies especially for BVOCs other than isoprene.

ANALYSIS OF VOLATILE COMPOUNDS IN DIFFERENT TYPES OF OAK BARREL USED IN THE AGING OF RUM
Revista CENIC Ciencias Químicas, 2021 It is well - known that during aging, several compounds are extracted from the oak barrels that have a positive influence on the sensory characteristics of the rum. The sensory improvement is the re sult of many transformations that take place among
