This paper examines the evolution of champagne prices in New York City from 1948 to 2013 by determining how many hours one must work, using after-tax income, to purchase a bottle of champagne. Each of the three brands analyzed—Bollinger, Louis Roederer, and Moët & Chandon—was divided into three tiers of nonvintage, vintage, and flagship champagne. The results indicated that all income groups worked fewer hours for entry-level nonvintage bottles of champagne, whereas the number of hours required to purchase flagship bottles generally increased.

Is it possible to exploit cognitive biases so that a non-professional taster prefers one wine to several other absolutely identical wines? To address this question, three complementary experiments were carried out. Each time, five wines were tasted blind in a tasting laboratory by 24 to 34 tasters. Converging evidence from the experiments shows that participants were not capable of identifying that some of the wines they were tasting were absolutely identical. Moreover, the results show that by providing information about the wines’ ratings, prices, or reputation, tasters’ expectations can be modified, and, as a result, their evaluations of the wines can be altered. Specifically, we show that it is possible to modify the ranking between different wines and to get tasters to prefer a wine over other absolutely identical wines. Finally, a surprising finding was that experienced tasters express stronger opinions and adapt their evaluations more strongly after being given manipulative information on the wines they taste.

This paper uses a difference-in-differences approach to analyze the treatment effect of a hail weather shock in a specific Swiss wine-growing region. We exploit a natural experiment from Switzerland's Three Lakes wine region in 2013 and examine its impact on the country's retail market. We find statistically significant (1%-level) effects of –22.8% and +2.8% for the volume and price of wine consumed, respectively. These effects can be interpreted as average treatment effects, which is the difference in outcomes between treatment and control groups using a pre-post shock study methodology. Several robustness checks confirm the statistical significance of the estimated effects and the initial assumptions.

Washington State enjoys an extraordinarily fast growing wine industry and is now the second largest wine producing state in the U.S. This paper examines the impact of this growth on the revenue of hotels and restaurants. Employing a dynamic quarterly panel model at the county level we show that the regional reputation as high quality wine county, as expressed by critical wine points in the national wine press, has a significant effect on the tourism industry. For Walla Walla, the most prominent wine county in the state, less than 17% of all restaurant and approximately 40% of all hotel revenue is tied to the wine cluster (2007). However, regional reputation is not long-living and needs constant replenishment. (JEL Classification: R11, R15, Q19)

Ties in the averages of scores that commercial wine competitions employ to grant awards are common, and these ties make it difficult for competition officials to differentiate between wines, they erode the perception of judges’ expertise, and they can make compliance with competition rules arithmetically impossible. Responding to requests from competition officials, this article presents and evaluates six methods for breaking ties in averages of scores. Results show that using an Olympic Average, the mean excluding the highest and lowest scores, is easy to calculate, easy to communicate, effective, unbiased, and it is not inconsistent with the implications of a method of aggregating scores that is not prone to ties.

Analyses and aggregations of the ratings that wine critics and judges assign to wines are made difficult by stochastic error and biases that remain even when wines are assessed blind to price, label, capsule, and closure. Stochastic error is due to the partially random nature of ratings. Cognitive and omitted-variable biases are due to anchoring, expectation, serial position, commercial, and other factors. Differences in decanting, filtering, aeration, and temperature can also affect ratings.

The European grapevine moth is one of the most pertinent viticulture pests. In recent years, the moth extended to New World countries, some of which started eradication programs. We used a dataset for Mendoza and a county-fixed effects regression model to estimate the impact of the moth on grape production across the province's counties. Our results suggest that the moth led to a decrease of up to 8% of Mendoza's grape production; however, this may have been worse without strong eradication efforts. We conclude that moth eradication programs may be economically justified in Argentina, and perhaps in other countries. (JEL Classifications: Q10, Q18, C23)

Studies suggest the inter-rater reliability of judges at wine competitions is higher than what would be expected by random chance, but lower than what is observed when experts in other fields make judgments specific to their expertise. To further contextualize the (un-) reliability of wine judging while also extending the study of fine water, we examine the inter-rater reliability of judges at an annual international competition for bottled waters. We find that the inter-rater reliability of water judging is generally better than chance and, at best, about the same as the inter-rater reliability of wine judging at some wine competitions. These results suggest that perceptible differences between fine waters exist but are less pronounced than those between fine wines and, also, that aesthetic standards with respect to fine waters exist but are currently less established than those for fine wines.

There are two main players in the Champagne wine industry; grape growers and Champagne houses. The former grow grapes and either produce their own Champagne wine or sell their fruit to Champagne houses. The latter only produce Champagne wine and do not grow grapes. However, Champagne houses invest heavily in advertisements to establish and maintain their brand's reputation. The grape market is characterized by the dominance of long-term supply contracts over spot contracts. Drawing on various theoretical models we suggest that the Champagne houses' advertising strategy and its associated positive externalities (spillover effects) on grape growers is a way of stabilizing vertical relations, i.e., keeping grape growers from producing Champagne wine themselves and thus maintaining a certain degree of monopoly power.

Wineries in the “old world” export almost 40% of their production. This study analyzes the influence of vertical and horizontal networks on export performance. We draw on a sample of 183 Spanish wineries and examine the main independent variables using a two-step Heckman model. We find positive effects of horizontal networks and—at a somewhat lower level—downstream vertical networks on export performance. (JEL Classifications: L66, M16, Q13)

In response to the work of Borges et al. (2012), Hulkower (2012) poses questions regarding the relative merits of the Condorcet and the Borda methods; a topic which has been taking place in socio-political studies for a very long time. While both approaches have their supporters and their detractors (Young, 1988; Risse, 2005; Saari, 2006), below we present the reasons for choosing Condorcet's method to obtain a consensus ranking of a region's vintage quality (Borges et al., 2012).

This paper analyzes the position of wine in the Danish alcohol market from 1978 to 2008. During this time period the market share of wine has doubled, assumingly due to a tax-induced change in relative prices as well as behavioral changes. This paper models the yearly observed market share of wine by unobserved component models which allow for adaptive trends including regressions with time varying coefficients. I find that the market share of wine has a steady upward trend even if it was temporarily broken by a tax reduction for liquor in 2001. (JEL Classification: C22, D11, L66)

We used a survey to investigate some motives for drinking red, sparkling, and white wine among 3,433 Norwegian respondents. Respondents with interest in wine drank all types of wine more frequently than those with little interest. Interest in cultural activities, which often are associated with wine consumption, also increased the frequency of consumption of all types of wine. Respondents who scored high on conspicuous attitudes drank sparkling and white wine more frequently than respondents with low scores. However, conspicuous attitudes did not affect the frequency of red wine consumption. (JEL Classifications: D12, Q13).
