Methods to assess the authenticity and traceability of wines have been extensively studied as enhancers of food quality, allowing producers to obtain market recognition and premium prices. Among analytical techniques, the volatilome profile attained by gas chromatography coupled with mass spectrometry is acquiring more and more attention by the scientific community, together with the use of chemometrics

The volatilome profile of three varieties of blanc wines from the Collio area (namely Ribolla Gialla, Malvasia and Friulano) between Italy and Slovenia, was determined by head space-solid phase micro extraction-gas chromatography-mass spectrometry, enhancing the carbonyl compounds identification with O-(2, 3, 4, 5, 6-pentafluorobenzyl)-hydroxylamine with the aim of identifying the autochthonous Friulano variety.

A two-step chemometric approach based on an unsupervised technique (PCA) followed by a supervised one (PLS-DA) allowed to identify possible markers for discriminating the Friulano Collio variety from the others, in particular two chemical classes were identified by PCA (ketones and long chain esters). PLS-DA showed 87% accuracy in classification. A correct classification (i.e. non-Friulano Collio) of a group of wines obtained from the same grape variety but produced in an extra-Collio area was obtained as well. The results confirmed the benefits of using a derivatization step prior to volatile organic compounds analysis.

Among methods to assess the authenticity and traceability of wines, volatilome profile of wines determined by head space-solid phase micro extraction-gas chromatography-mass spectrometry, enhanced by the carbonyl compound identifications with O-(2, 3, 4, 5, 6-pentafluorobenzyl)-hydroxylamine, may have a key role in conjunction with chemometrics and, in particular with principal component analysis and partial least square discriminant analysis.

Among methods to assess the authenticity and traceability of Friulano wine, volatilome profile of wines determined by head space-solid phase micro extraction-gas chromatography-mass spectrometry, enhanced by the carbonyl compound identifications with O-(2, 3, 4, 5, 6-Pentafluorobenzyl)Hydroxylamine hydrochloride, may have a key role in conjunction with chemometrics.

Few works investigated both wine traceability with a volatilome enhancer and chemometrics of the Friulano wine variety obtaining such an improvement in this wine variety discrimination.

This paper aims to investigate the wine consumption among young people belonging to the so-called millennial generation

This study uses a questionnaire and a choice experiment (CE) with a multinomial logit model (MNL), implementing a random parameter logit model (RPL), to investigate the attitudes of millennials towards wine consumption, their purchasing behaviours and their willingness to pay for attributes of the products; in particular regarding the follwing: region of origin, “winescape”, certification, carbon footprint claim and price.

Millennials appear to drink wine less frequently; they consume it more often in social on-premise settings, having a slightly higher willingness to pay and preferring carbon-neutral brands when choosing wine.

The limitation of this research was the analysis of a simulated situation where consumers declared their intention to purchase and not the effective purchase behaviour in the market.Further research should investigate wider millennials groups, also using the new media communication tools that characterise the communication behaviour of Generation Y. In this way, it would be possible to interview a millennial group at the national or international level.

The research identifies some characteristics of millennials’ habits that can take into account the strategies of wine companies in order to develop a constructive relationship with Generation Y in Italy.

This research contributes to knowledge regarding the wine consumption habits of Italian millennials.

This paper applies discrete choice models to consumption situations in order to analyse millennials' preference and their willingness to pay for some innovative attributes of wine, in particular the carbon footprint.
