This article is the first of its kind to estimate econometrically the supply elasticity of California wine grapes. Wine grapes constitute the single largest crop in the state of California in terms of total receipts. Allowing for the dynamic adjustments of quasi-fixed inputs, we estimate simultaneous systems of equations for California's four major wine grape growing regions and eight of the most widely grown varieties. We find that California wine grape production is, on the whole, inelastic with respect to prices received. The variety showing the most price responsiveness is Chardonnay. There appears to be no significant difference in price responsiveness between the coastal and inland growing regions, or between red and white grape varieties. (JEL Classification: Qll, Q13, R14)

We study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980 and 1992), can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies (from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments, the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality much more than natural endowments, the effect of which is negligible. (JEL Classification: L66, Q12, Q13, Q16)

The Texas wine industry of the United States has experienced substantial growth in recent years and yet is constrained by a significant lack of supply of Texas grown grapes. Using a real options framework we examine the role that wine grape price uncertainty plays on the financial decision to invest in vineyard operations in the state of Texas. Given reasonable estimates of required rates of returns, investment and operating costs for typical Texas vineyards, it is found that grape price uncertainty results in a delay in investment and subsequently a lack of grape supply. This delay in investment, known as hysteresis, is often found in situations involving large fixed investments combined with uncertain returns. In general the results indicate that average prices for Texas grapes would have to increase by 30 to 40 percent in order for a significant expansion in Texas vineyards to take place.

The purpose of this paper is to measure the impact of Robert Parker's oenological grades on Bordeaux wine prices. We study their impact on the so-called en primeur wine prices, i.e., the prices determined by the château owners when the wines are still extremely young. The Parker grades are usually published in the spring of each year, before the wine prices are established. However, the wine grades attributed in 2003 have been published much later, in the autumn, after the determination of the prices. This unusual reversal is exploited to estimate a Parker effect. We find that, on average, the effect is equal to 2.80 euros per bottle of wine. We also estimate grade-specific effects, and use these estimates to predict what the prices would have been had Parker attended the spring tasting in 2003. (JEL Classification: C21, D89, L15).

As competition for water resources increases and water availability in arid regions declines, agricultural producers are encouraged to adopt water-conserving strategies. This study examines the economic feasibility of implementing wine grapes in northwest Nevada as a diversification and water conservation strategy. Results show profit potential when vitis interspecific wine grape varieties are produced in the region. Net returns based upon point estimates from two separate analyses show per-acre net returns at $1,065 and $3,022, respectively. However, the large variation in potential net returns shown in the risk analysis, combined with a high capital investment cost of more than $17,000 per acre, may preclude producers from exercising their option to adopt wine grape production. Also, including wine grapes in the on-farm crop portfolio will affect its risk and return characteristics, likely impacting producer preferred level of wine grape adoption.

Bordeaux wines have been made in much the same way for centuries. This article shows that the variability in the quality and prices of Bordeaux vintages is predicted by the weather that created the grapes. The price equation provides a measure of the real rate of return to holding wines (about 2–3% per annum) and implies far greater variability in the early or ‘en primeur’ wine prices than is observed. The analysis provides a useful basis for assessing market inefficiency, the effect of climate change on the wine industry and the role of expert opinion in determining wine prices.

This paper examines empirically two distinguishing aspects of the world's wine regions: their degree of specialization in certain varieties, as measured by a varietal intensity index; and their similarity with the varietal mix of other regions, as measured by a varietal-based regional similarity index. Twelve of the most important wine-producing countries, that together account for all but one-eighth of the world's winegrapes, are included in the analysis. The data refer to circa 2000 (or 1999 for EU member countries, since that is their most recent census data). These indexes provide a baseline against which to compare more recent and future vintages. They will be especially useful as producers and regulators respond at varying speeds to the impacts of climate changes, in addition to market developments, on the optimal location of production of different varieties around the world.

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.

The United States wine industry has experienced tremendous growth in the past twenty-five years. The number of wineries in the United States has grown to almost 5000, located in all fifty states, and creating over a million full time jobs. Alcohol distribution laws that hinge on the Supreme Court's reconciliation of the Twenty-first Amendment and the Commerce Clause have significantly hindered the industry's ability to expand. Current interpretations of the 21st Amendment give states unprecedented freedom to regulate interstate commerce in alcoholic beverages. The resulting regulatory diversity presents problems both domestically and internationally. (JEL Classification: K2, L5, N4)

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)

This paper analyzes stock market reaction to court decisions related to the differential treatment of in-state and out-of-state internet wine sales. Several states had differential laws governing internet sales of wine directly to consumers for in-state and out-of-state wineries. These laws were possibly more harmful to small wine producers as their products are less likely to be carried by retailers. In May of 2005, The Supreme Court of the United States declared these practices unconstitutional. Prior to the Supreme Court granting the writ of certiorari there was a circuit split on the issue. Our study seeks to measure the impact of the Courts' decisions on the stock returns of wineries using standard event study methodology. The results show a negative stock market reaction to publically traded large wineries to the Supreme Court ruling. It appears that differential treatment laws were, indeed, beneficial to the large wineries. (JEL Classification: G18, Q28)

Using a dataset that spans the period 1996 to 2007 and contains transaction prices for all reported auctions at the Chicago Wine Company, we analyze how the prices of high-end wines have evolved during this time period. The best wines according to characteristics like vintage, rating and ranking earn higher returns and tend to have a lower variance than poorer wines. Nevertheless, the different categories of wines seem to follow a rather similar trend over the long run. Wine returns are only slightly correlated with other assets and can consequently be used to reduce the risk of an equity portfolio. Wine looks even more attractive when the investor also has concerns about the skewness of his portfolio. However, the part to be invested in wine is reduced once the kurtosis is included into the analysis. Finally, it seems advisable to diversify across different wine categories as their short-run movements are partially independent of each other. First growths and wines rated as extraordinary by Robert Parker deliver the best tradeoff in terms of portfolio expected returns, variance, skewness and kurtosis for most investor preference settings under consideration.

The existing literature on the return to wine is mixed. Some studies have found wine to be an unattractive investment option and others have found wine to be an investment class that provides excess risk adjusted returns. However, provided the return to wine does not have a strong positive correlation with standard financial assets, even if the return to wine is low, it is possible that including wine in an investment portfolio will provide a diversification benefit. Here the repeat sales regression methodology is used to estimate the return to Australian wine, and the return is shown to be lower than for standard financial assets. Several measures are then used to show that despite the return to Australian wine being lower than the return to standard financial assets, wine does provide a modest diversification benefit.

Judge performance is a critical component of a wine competition's success. A number of studies have shown that wine judges may differ considerably in their opinions. In this paper, we have conducted an in-depth examination of wine judge performance at a U.S. wine competition. Three characteristics of judge's performance are examined: bias, discrimination ability, and variation. Based on the analysis, we can identify the judges who had discrepant scoring patterns and can gain insight into which of the three characteristics cause particular judges to disagree. The evaluation of wine judge performance through these three characteristics may provide useful information for training them to have consistent performance and in assisting competition coordinators in judge selection.

This paper evaluates whether tasting notes—the brief testimony that describes the sensory properties of wines—add value. The analysis is based on a sample of over 2700 recent-vintage cabernet sauvignon wines evaluated by Wine Spectator. I estimate a dynamic wine price model to evaluate the marketing effect of the note, controlling for quality measures as well as other wine characteristics. The results indicate that the length of the tasting note exerts a strong positive influence on the wine's price, even after controlling for quality. A 10 percent increase in the number of characters in the tasting note (about 23 additional characters) contributes about two to four dollars to the price of the wine. Further analysis reveals that the value of the tasting note does not come from the “analytical” words contained in the note but rather, from the more subjective component of it.
