It must be additionally be stressed that some studies28 suggest that most wine consumers do not understand the scope and consequences of nutritional information; for example, perhaps due to unfamiliarity, they find it difficult to relate the energy value of wine per 100 ml to the amount of calories taken in through normal consumption, not least because of the variety of sizes of glasses and goblets, which can be misleading (a good-sized goblet, filled half full, can hold 250-300 ml). In my opinion, however, the problem lies precisely in the risk of incorrect assessment of the information provided. In general, the greatest sensitivity to nutritional information belongs to the younger segment, which is more oriented towards assessing the risks of consuming high-calorie foods29 . In the case of wine, however, the energy content is essentially linked to two factors: the alcohol content, and the possible presence of residual sugar. This means, for example, that it is dry wines with low alcohol content that appear more 'virtuous', although they also often have low quality. To give a trivial example, Amarone, considered among the best wines in the world, will certainly have more calories than a wine sold in bric at the supermarket; consequently, there is a risk that the latter type, which is certainly poorer from an organoleptic (and cultural) point of view, will be preferred to the former. If we then relate this to the market segmentation typical of wine, the result will be to steer the less experienced public towards the consumption of lowquality wines, while it is presumable to think that nutritional information will have no significant effect on experienced consumers, who are unlikely to give up product quality for fear of consuming too many calories. data related to the suggested maximum glass size for consumption.

Insights on consumers' preferences for nutritional information on wine labelling, in Nutrients, 2018, 10.11: 1667, suggest instead that consumers prefer a full indication of nutritional elements. 28 E.
