The interplay of bottle storage and wood ageing technology: Volatile and sensor...
Caldeira, Ilda; Anjos, O.; Vitória, Cláudia; Alves, Sheila Oliveira; Fernandes, Tiago A.; Canas, Sara; Catarino, SofiaWine spirits are typically aged in wooden barrels. Recently, alternative ageing technologies, such as those using wood fragments in wine spirits stored in stainless steel tanks, have been investigated. However, a signifcant lack of information regarding the potential evolution of these beverages after bottling still remains. This study assessed the 12-month evolu tion of aroma in bottled wine spirits aged with ...
Enhancing strawberry tree fruit spirit: effects of oak wood ageing
Anjos, O.; Antunes, Carlos Alberto Simões; Pedro, Soraia; Alves, Sheila Oliveira; Canas, Sara; Caldeira, IldaThe present study focuses on the impact of wood ageing on strawberry tree fruit spirit, a high quality beverage in Mediterranean regions, particularly Portugal. It explores the chemical and sensory changes resulting from ageing the spirit for two periods of time with oak wood of varying toasting levels. Analysis included acidity, colour, pH, dry extract, volatile compounds (methanol, acetaldehyde, ethyl acetate...
Characterisation of low molecular weight compounds of strawberry tree (Arbutus ...
Anjos, O.; Antunes, Carlos Alberto Lopes; Alves, Sheila Oliveira; Canas, Sara; Caldeira, IldaThere is a trend towards the commercialisation of strawberry tree fruit spirit (AUS) with wood ageing, motivated by its favourable sensory characteristics. Additionally, further studies are necessary to elucidate the optimal conditions regarding ageing time and toasting level. This study evaluated the changes in colour and low molecular weight compounds (LMWC) of AUS aged for three and six months using oak wood...

Influence of the storage in bottle on the antioxidant activities and related ch...
Alves, Sheila Oliveira; Lourenço, Sílvia; Anjos, O.; Fernandes, Tiago A.; Caldeira, Ilda; Catarino, Sofia; Canas, SaraDifferent ageing technology of wine spirits (WSs) has been investigated, but little has been published on the chemical evolution of aged WS during storage in bottle. The purpose of this study was to examine how 12 months of storage in bottle affected the evolution of antioxidantactivity (DPPH, FRAP and ABTS assays), total phenolic index (TPI) and low molecular weight (LMW)compounds content of the WSs aged throu...
Natural blending as a novel technology for the production process of aged wine ...
Lourenço, Sílvia; Anjos, O.; Caldeira, Ilda; Alves, Sheila Oliveira; Santos, Nádia; Canas, SaraThe blending of wine spirits (WSs) produced in different ageing conditions is a key operation to impart specific features, enhance complexity, increase the final product’s quality and ensure brand consistency over the years, but requires time, labour and experienced blenders. This work aimed to develop a novel technology, natural blending, towards innovation and a more sustainable production process, adding val...
Application of near-infrared spectroscopy to characterize volatile phenols and ...
Anjos, O.; Caldeira, Ilda; Fernandes, Tiago A.; Pedro, Soraia; Vitória, Cláudia; Alves, Sheila Oliveira; Catarino, Sofia; Canas, SaraVolatile phenols are low molecular weight aromatic alcohols, with particular importance in wine spirits aged with wood due to their strong influence on sensory profile.

Alves, Sheila Oliveira; Lourenço, Sílvia; Fernandes, Tiago A.; Anjos, Ofélia; Caldeira, Ilda; Catarino, Sofia; Canas, SaraThe traditional ageing technology (TAT) has always been associated with oak barrels ageing and involves staging the wine distillate (WD) in wooden barrels with a continuous innate diffusion of oxygen through the wood and space between staves, under which the beverage spirit undergoes positive changes that contribute to the enhancement of its chemical composition and sensory properties.
Changes of the physicochemical characteristics of aged wine spirits during the ...
Lourenço, Sílvia; Soares, Amélia; Mota, Deolinda; Anjos, O.; Caldeira, Ilda; Alves, Sheila Oliveira; Canas, SaraThe wine spirit (WS) is a specific beverage obtained by the distillation of wine. Initially, the wine distillate is essentially made up of ethanol and water, and its physicochemical characteristics mainly result from the wine and distillation system used. During the ageing process, the distillate contacts with the wood and, with the mediation of oxygen, organic compounds are extracted from the wood and undergo ...
