TL;DR: The chemical composition of aguardente - Brazilian sugar cane alcoholic drink - under aging during in 20 L oak casks was evaluated for 390 days as mentioned in this paper, which showed higher concentrations of volatile acidity, esters, aldehydes, furfural, higher alcohols, congeners, dry extract, and tannin.
Abstract: The chemical composition of aguardente - Brazilian sugar cane alcoholic drink - under aging during in 20 L oak casks was evaluated for 390 days. Aging sugar cane aguardente in wood casks improves the sensorial quality of the distillate. The concentrations of ethanol, volatile acidity, esters, aldehydes, furfural, higher alcohols (n-propylic, isobutylic and isoamylics), methanol, copper, dry extract, tannins, and color of the aged sugar cane aguardente were analysed at 0, 76, 147, 228, 314, and 390 days of storage. After 390 days of aging the sugar cane aguardente presented higher concentrations of volatile acidity, esters, aldehydes, furfural, higher alcohols, congeners, dry extract, and tannin. Its color became golden. The concentrations of ethanol and methanol did not change and the copper content decreased slightly. The aging of the sugar cane aguardente in oak casks for 390 days changed the chemical composition of the distillate. However, the aged sugar cane aguardente met the quality standards established by Brazilian laws.

TL;DR: The Brazilian woods, similar to oak, were jequitibá rosa and cerejeira, which presented the highest contents of some maturation-related compounds, such as vanillin, vanilic acid, syringaldehyde and sinapaldehyde.

TL;DR: This novel approach may reduce current limitations that exist with traditional methods of detecting fermentation by-product congeners, which restrict the use of alcohol congener analysis internationally and for other medico-legal scenarios.
Abstract: For many decades traditional alcohol congener analysis has provided the concentrations of fermentation by-product congeners found in blood, to ascertain if the claims of an individual regarding the alcoholic beverage(s) they have consumed were feasible, assisting in cases where after-drinking is involved. However, this technique does not provide information on the exact alcoholic beverage(s) consumed. More recently, ingredient biomarker congeners specific to certain alcoholic beverages have been detected in blood, making it possible to identify the particular alcoholic beverage consumed and therefore the source of alcohol (albeit only for a limited number of beverages). This novel approach may reduce current limitations that exist with traditional methods of detecting fermentation by-product congeners, which restrict the use of alcohol congener analysis internationally and for other medico-legal scenarios. This review examines the forensic application of alcohol congener analysis in determining the source of alcohol and other techniques.

TL;DR: In this paper, the chemical composition of Brazilian sugar cane spirits and cachacas and compare it to the identity and quality standards established by national legislation was determined and the results indicate that producers still face challenges in adopting best practices to produce these beverages in order to guarantee their quality and standardization.

TL;DR: In this article, the authors evaluated some aspects of the chemical composition and sensorial acceptance of sugar cane spirit aged for 3 years in casks of different types of wood (peanut wood, araruva or striped wood, red cabreuva, oak, cherrywood, Brazilian gold wood, purple tabebuia, cariniana legalis, and pear tree).
Abstract: This study evaluated some aspects of the chemical composition and sensorial acceptance of sugar cane spirit aged for 3 years in casks of different types of wood (peanut wood, araruva or striped wood, red cabreuva, oak, cherrywood, Brazilian gold wood, purple tabebuia, cariniana legalis, and pear tree). The simple alcoholic distillate which originated the sugar cane spirit was produced at the Distillery of ESALQ/USP. After aging, the sugar cane spirits were analyzed in terms of ethanol concentrations o, volatile acidity, furfural, aldehydes, esters, higher alcohols, methanol, copper, total phenolic compounds, color, and sensorial acceptance. Regardless the type of wood the casks were made of, the aged sugar cane spirits became darker and presented higher concentrations of volatile acidity, furfural, esters, higher alcohols, congeners, and total phenolic compounds than the simple alcoholic distillate. On the other hand, the aged sugar cane spirits presented lower concentrations of aldehydes, methanol, and copper than the simple alcoholic distillate. The statistical analysis, considering the global physicochemical composition of the sugar cane spirits aged in the casks made of different types of wood, showed similarities among the sugar cane spirits aged in the casks of peanut wood, araruva or striped wood, and cariniana legalis. It also indicates similarities among the sugar cane spirits aged in the casks of red cabreuva and pear tree and among the sugar cane spirits aged in the casks of oak, cherrywood, Brazilian gold wood, and purple tabebuia. The sugar cane spirits aged in the casks of the different types of wood were in accordance with the composition and quality standards established by the Brazilian laws. The sugar cane spirit aged in oak presented the best sensorial acceptance. Among the Brazilian woods, purple tabebuia, peanut wood, red cabreuva, cherrywood and pear tree were those that produced sugar cane spirits with better sensorial qualities.

TL;DR: The effects and time required for maturation are highly variable and are influenced by a wide range of factors, particularly the type of barrel used as discussed by the authors, and there has been increasing interest in methods of predicting, controlling and simulating the effects of maturation.
Abstract: A wide range of distilled beverages, including whisky and cognac, continue to be matured for many years in oak barrels. During maturation a range of physical and chemical interactions take place between the barrel, the surrounding atmosphere and the maturing spirit which transform both the flavour and composition of the drink. The effects and time required for maturation are highly variable and are influenced by a wide range of factors, particularly the type of barrel used. As our understanding of the process has improved there has been increasing interest in methods of predicting, controlling and simulating the effects of maturation.

TL;DR: This paper showed that the formation of acetaldehyde, acetic acid, and ethyl acetate originates in the distillate, while ethanol lignin, aromatic aldehydes, sugars and some acetic acids are reaction products of the distillation and wood components.
Abstract: Studies of the chemical mechanisms involved in the maturation of whiskey showed that the formation of acetaldehyde, acetic acid, and ethyl acetate originates in the distillate, while ethanol lignin, aromatic aldehydes, sugars and some acetic acid are reaction products of the distillate and wood components. Storage conditions affect these reactions. For example, barrel wood is more reactive when a barrel is charred, causing a higher congener level in the product of the first filling than that of a comparable filling in an uncharred barrel. As the barrel is reused, the product congener level approaches that of the uncharred barrel. The effect of recharring the barrels on congener formation is also discussed. The entry proof also affects the levels of congeners present in the final product. As the entry proof increases, those congeners that originate from barrel components decrease. Warehouse temperatures are directly related to the rate these congeners are formed. The implication of these relationships on the maturation of whiskey is discussed.
