Organic wines are increasingly produced and appreciated. Since organic production is more costly, a crucial question is whether they benefit from a price premium. We estimate hedonic price functions for Piedmont organic and conventional wines. We use data on the production side in addition to variables of interest for consumers. Our results show that, along with characteristics of interest to consumers, some farm and producer characteristics not directly relevant for consumers do significantly affect wine prices. We find that organic wine tends to obtain higher prices than conventional wine. The price premium is not simply an addition to other price components, but organic quality modifies the impact of the other variables on price. (JEL classification: C21, D49, L11, Q12)

The Italian wine supply chain has performed well in recent decades both in terms of profitability and success on the domestic and international markets. This is despite the fact that it is fragmented in terms of products, prices and consumption context, and, in particular, despite the fact that it is characterised by an organisation that hinders the full exploitation of economies of scale. This paradox has not been investigated in literature. We propose several elements in support of the hypothesis that the Italian wine sector’s success is linked to favourable elements of the Porter Diamond Model (5 out of 6) but also to the “district” nature of a large part of the sector. The presence of numerous networks, some of which are formal and others informal, gives most Italian local production systems specialising in grapes and wine the characteristics of industrial districts, due to the local social capital that is stratified there. These networks include operators such as Cooperatives and Consorzi di Tutela, upstream and downstream industries and services, tourism, research and educational bodies. Such networks can overcome the weakness represented by the low concentration and small average size of the operators. To support this hypothesis, we analyse the historical evolution of the sector and its drivers, the structural features of the different phases of the wine chain (grape growing, winemaking, bottling and distribution), the market relationships within the chain and the national and European policies favouring the sector. This analysis also underlines the differences between the Italian sector and its competitors from the Old and New World.

In this paper we estimate how a variety of subjective measures of quality taken from the published opinions of several experts on Italian wines (Barolo and Barbaresco) are determined by the weather conditions during the relevant season, in order to assess their reliability. Since these measures of quality are only ordinal, we estimate their determinants using an ordered probit model. The method provides measures of the determinants of vintage quality ratings and suggestions on the reliability of each expert. (JEL Classifications: D12, Q11, Q13)
