Phenolic compounds of wine spirits resulting from different ageing technologies: behaviour during the storage in bottle


Phenolic compounds are released from the wood into the wine spirit (WS) during the ageing process, and are of utmost importance to the colour, flavour, taste and the overall quality acquired by this spirit drink.1 Their concentrations in the WS and the related effects mainly depend on the kind of wood (oaks vs chestnut), toasting level and ageing technology (traditional using wooden barrels vs alternative).1,2,3

Recent research conducted by our team has been focused on alternative technology towards sustainable ageing of WS resorting to wooden staves combined with micro-oxygenation (MOX).2,3 In the Project CENTRO-04-3928-FEDER-000001, the same wine distillate was aged for 18 months in 1000 L stainless steel tanks with wood staves inside (Limousin oak or chestnut) and MOX (flow rate 2 mL/L/month), and in 250 L barrels made of the same kinds of wood, in duplicate. Despite the promising results achieved, showing faster ageing and the production of high quality aged WSs resulting from the alternative technology compared to those resulting from the traditional one, it is imperative to assess their quality during the storage in bottle to fully validate the new technology. Therefore, the second phase of the investigation is currently made under the Project CENTRO-04-3928-FEDER-000028, studying the chemistry underlying the storage in bottle in order to understand if the features imparted by the ageing technology are retained or if they do not persist. The present work is focused on the behaviour of phenolic compounds of the aged WSs during this stage. For this purpose, the eight aged WSs (from the four modalities: chestnut barrels, Limousin oak barrels, stainless steel tanks with chestnut wood staves and MOX, and stainless steel tanks with Limousin oak wood staves and MOX) were bottled on the same day in 750 mL amber glass bottles (two bottles per modality). The cork stopper and the bottleneck were sealed with parafilm to prevent evaporation. The bottles were stored in the cellar of INIAV-Dois Portos. Sampling was carried out in the beginning and after 12 months of storage, and the phenolic compounds (gallic, syringic, ferulic and ellagic acids, vanillin, syringaldehyde, coniferaldehyde, sinapaldehyde, umbelliferone and scopoletin) were analysed by a HPLC method developed and validated in our laboratory.4

The ANOVA results revealed that most of the compounds’ contents did not change significantly after 12 months of storage in bottle. In addition, the phenolic differences between the WSs resulting from the four ageing modalities remained, except for ferulic acid. Therefore, in these experimental conditions, this stage allowed preserving the phenolic composition imparted to the WS by the alternative ageing technology.

Novel analytical technologies for wine fingerprinting in and beyond the laboratory

For characterization, sensory designing and authentication rapid analytical technologies have become available. Some, like Proton Transfer Reaction Mass Spectrometry allow a rapid spectrum of the volatile compounds of wines. Combined with chemometrics wines can be characterized. The same approach can be used to calculate the results of virtual mixtures and allow formulation of constant quality blends. Other new techniques and portable devices based on spectroscopy allow measurements on production sites and in grocery stores, even for the smart consumer. We will present some examples of the application of these techniques for authentication of wines, both in the laboratory and on site.

Dialing in grapevine water stress indicators to better reflect holistic stress responses

Current remote sensing strategies rely heavily on reflectance data and energy balance modelling using thermal imagery to estimate crop water use and stress. These approaches show great promise for driving precision management decisions, but still require work to better understand how detected changes relate to meaningful physiological changes. Under water stress, grapevines exhibit a range of responses involving both biological and physical changes within leaves and canopies.

Analysis of volatile composition of interaction between the pathogen E. necator and two grapevine varieties

Volatile organic compounds (VOCs) are emitted by nearly all plant organs of the plants, including leaves. They play a key role in the communication with other organisms, therefore they are involved in plant defence against phytopathogens. In this study VOCs from grapevine leaves of two varieties of Vitis vinifera infected by Erysiphe necator were analysed. The varieties were selected based on their susceptibility to pathogen, Kishmish Vatkana has the Ren1 resistance gene and Zamarrica showed high susceptibility in previous trials.
