Wine Review Descriptors as Quality Predictors: Evidence from Language Processing Techniques

Chenyu Yang, Jackson Barth, Duwani Katumullage and Jing Cao
Pages: 64-80
Full Text PDF
Abstract

There is an ongoing debate on whether wine reviews provide meaningful information on wine properties and quality. However, few studies have been conducted aiming directly at comparing the utility of wine reviews and numeric measurements in wine data analysis. Based on data from close to 300,000 wines reviewed by Wine Spectator, we use logistic regression models to investigate whether wine reviews are useful in predicting a wine’s quality classification. We group our sample into one of two binary quality brackets, wines with a critical rating of 90 or above and the other group with ratings of 89 or below. This binary outcome constitutes our dependent variable. The explanatory vari- ables include different combinations of numerical covariates such as the price and age of wines and numerical representations of text reviews. By comparing the explanatory accuracy of the models, our results suggest that wine review descriptors are more accurate in predicting binary wine quality classifications than are various numerical covariates— including the wine’s price. In the study, we include three different feature extraction methods in text analysis: latent Dirichlet allocation, term frequency-inverse document frequency, and Doc2Vec text embedding. We find that Doc2Vec is the best performing feature extraction method that produces the highest classification accuracy due to its capability of using contextual information from text documents.

Keywords: classification, logistic regression, text analysis, wine review.

A “Sideways” Supply Response in California Winegrapes

Sarah Consoli, Elizabeth A. Fraysse, Natalya Slipchenko, Yi Wang, Jahon Amirebrahimi, Zhiran Qin, Neil Yazma and Travis J. Lybbert
Pages: 42-63
Abstract

This paper explores growers’ supply response to the 2005 “Sideways effect” demand shock (Cuellar, Karnowsky, and Acosta, 2009) triggered by the 2004 release of the movie Sideways. We use a modified difference-in-difference approach to evaluate the supply response in California and regional supply response differences within California. We use U.S. Department of Agriculture data for the period 1999–2012 and find evidence of a supply response in the post-release period that is consistent with the “Sideways effect” on wine demand. The positive supply response for Pinot Noir is stronger than the negative response for Merlot and concentrated in lower value Central Valley vineyards.

Keywords: California, grapes, Merlot, Pinot Noir, supply response, wine.

Using Neural Network Models for Wine Review Classification

Duwani Katumullage, Chenyu Yang, Jackson Barth and Jing Cao
Pages: 27-41
Full Text PDF
Abstract

Wines are usually evaluated by wine experts and enthusiasts who give numeric ratings as well as text reviews. While most wine classification studies have been based on conventional stat- istical models using numeric variables, there has been very limited work on implementing neural network models using wine reviews. In this paper, we apply neural network models (CNN, BiLSTM, and BERT) to extract useful information from wine reviews and classify wines according to different rating classes. Using a large collection of wine reviews from Wine Spectator, the study shows that BERT, a neural network framework recently developed by Google, has the best performance. In the two-class classification (90–100 and 80–89), BERT achieves an accuracy of 89.12%, followed by BiLSTM (88.69%) and CNN (88.02%). In the four-class classification (95–100, 90–94, 85–89, and 80–84), BERT yields an 81.57% accuracy, while the other two produce an 80% accuracy. The neural network models in the paper are independent of domain knowledge and thus can be easily extended to other kinds of text analysis. Expanding the limited work on wine text review classification studies, these models are up-to-date and provide valuable additions to wine data analysis.

Keywords: BERT, BiLSTM, CNN, natural language processing, neural networks, wine reviews.

Estimating Supply Functions for Wine Attributes: A Two-Stage Hedonic Approach

Edward Oczkowski
Pages: 1-26
Abstract

A vast body of literature exists on estimating hedonic price functions, which relate the price of wine to its attributes. Some existing literature has employed producer-specific variables such as quantity sold and producer reputation in hedonic functions to potentially capture supply influences on prices. This practice is inconsistent with the original Rosen (1974) hedonic theoretic foundation. To overcome this deficiency, we extend the literature by using the Rosen two-stage approach, employing data from multi-markets for similar wines to estimate inverse supply functions. The application to Australian produced wines sold in different coun- tries demonstrates the importance of a wine’s quality and age as attributes in inverse supply functions. Results imply the additional costs of producing better quality and older wines are increased as both quality and age are increased. Estimates also suggest that lower marginal costs for attributes are associated with a smaller producer size and older more established producers.

Keywords: attribute supply, Australian wines, wine prices.

Business Cycles and Alcohol Consumption: Evidence from a Nonlinear Panel ARDL Approach

Elkhan Richard Sadik-Zada and Britta Niklas
Pages: 429-438
Full Text PDF
Abstract

This study revisits the relationship between economic variables and alcohol consumption from a macro perspective. Focusing explicitly on the asymmetries of the responsiveness of alcohol consumption during the expansion and contraction phases of the business cycle, asymmetric panel estimators are employed. We employ a nonlinear autoregressive distributed lag model for a panel of 24 countries for the period 1961 to 2014. Findings show that expansion leads to a long-term increase in average alcohol consumption, while during contraction, the level of average alcohol consumption persists. Expansion, together with a pronounced reduction in the unemployment rate could, however, lead to a net reduction of gross alcohol and wine consumption. Nonetheless, if the recession corresponds with a surge in unemployment, this leads to a long-run increase in the level of total gross alcohol consumption but a decrease in wine and beer consumption. Reduction in unemployment does not lead to a reduction in beer consumption, as pre-expansion levels of beer consumption persist.

How Many Latours Is Too Many? Measuring Brand Name Congestion in Bordeaux Wine

Christopher Buccafusco, Jonathan S. Masur and Ryan Whalen
Pages: 419-428
Full Text PDF
Abstract

Firms rely on brand names to market goods to consumers, and consumers rely on brand names to locate goods that satisfy their preferences. If multiple firms are using the same or similar names, consumers may be confused about which product to buy, and firms may not obtain the benefits of their investments in quality. Recently, both firms and scholars in a number of industries have expressed concern about brand name congestion— too many firms clustering around too few terms. This paper applies computational linguistic analysis to chateau names in the Bordeaux wine region to study the degree of brand congestion within a mature, traditional, and high- value market. We find that Bordeaux producers have highly similar names to one another, far more than in comparable wine regions such as California and Alsace. More than a quarter of all Bordeaux producers have a name that is identical or nearly so to at least one other producer, and many terms are claimed by dozens of different producers. Interestingly, however, we find that the most famous and renowned producers have names that tend to be more distinctive than their less famous brethren.

Expensive and Cheap Wine Words Revisited

Kevin W. Capehart
Pages: 411-418
Abstract

Previous work has quantitatively analyzed expert wine descriptions to identify some so-called “expensive” and “cheap” words that are indicative of a wine’s price. This paper revisits that work. In particular, I examine whether words previously identified as expensive and cheap ones are still indicative of a wine’s price when using the same methods and a different, larger dataset. My findings mostly confirm previous conclusions, although many directions for further research into expensive and cheap wine words remain open.

Keywords: expert evaluation, wine.

Vertical and Horizontal Networks and Export Performance in the Spanish Wine Industry

Juan-Ramón Ferrer, Silvia Abella-Garcés and Raúl Serrano
Pages: 400-410
Abstract

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— down- stream vertical networks on export performance.

Keywords: export performance, networks, Spanish wine sector.

The Water of Life and Death: A Brief Economic History of Spirits

Lara Cockx, Giulia Meloni and Johan Swinnen
Pages: 355-399
Abstract

Spirits represent around 50% of global alcohol consumption. This sector is much less studied than other alcoholic beverages such as wine or beer. This paper reviews the economic history of spirits and analyzes recent trends in the spirits markets. The technology to produce spirits is more complex than for wine or beer. Distillation was known in ancient Chinese, Indian, Greek, and Egyptian societies, but it took innovations by the Arabs to distill alcohol. Initially, this alcohol was used for medicinal purposes. Only in the Middle Ages did spirits become a widespread drink. The Industrial Revolution created a large consumer market and reduced the cost of spirits, contributing to excess consumption and alcoholism. Governments have intervened extensively in spirits markets to reduce excessive consumption and to raise taxes. There have been significant changes in spirits consumption and trade over time. Over the past 50 years, the share of spirits in global alcohol consumption increased from around 30% to around 50%. In the past decades, there was strong growth in emerging markets, including in China and India. Recent developments in the spirits industry include premium- ization, the growth of craft spirits, and the introduction of terroir for spirits.

Keywords: alcohol and health, alcohol regulations, craft and industry concentration, distillation technology, globalization and convergence of alcohol preferences, spirits.

Wine Ratings: Seeking a Consensus among Tasters via Normalization, Approval, and Aggregation

Olivier Gergaud, Victor Ginsburgh & Juan D. Moreno-Ternero
Pages: 321-342
Abstract

The modern era of wine journalism has provided abundant information about wines and wide- spread use of numerical rating systems. A tiny difference, especially at the top of the distribu- tion of ratings, may have striking consequences on wine sales and investment returns. This article provides a general framework to obtain a consensus among tasters’ opinions (reflected as numerical wine ratings) via three subsequent stages: normalization, approval, and aggregation. It is inspired by contributions in political science, social choice, game theory, and operations research. We apply it to the Judgment of Paris as well as to rank 2018 en-primeur Bordeaux wines, rated by five international experts.

Restaurant Wines: Bottle Margins and the By-the-Glass Option

James A. Dearden, Xiaohui Guo & Chad D. Meyerhoefer
Pages: 305-320
Full Text PDF
Abstract

Using a sample of New York City restaurants, we examine the relationship between a wine’s bottle margin and whether the restaurant offers that same wine by the glass. We find that restaurants offer less expensive wines by the glass but set higher margins on these bottles than for similar wines offered only in bottles. Overall, offering wine by the glass is associated with a 5.0% increase in the bottle price and a 12.2% increase in the bottle margin. We find similar results for retail and wholesale markups of wine bottles. Our results offer evidence that settles a theoretical ambiguity in the menu-pricing literature (Anderson and Dana, 2009) about whether to raise or lower the price of a high-quantity package when introducing a low-quantity package of a good, as it applies to restaurant wine pricing.

Market Segmentation and Dynamic Analysis of Sparkling Wine Purchases in Italy Francesca Bassi

Francesca Bassi, Fulvia Pennoni & Luca Rossetto
Pages: 283-304
Abstract

The Italian market of sparkling wines increases as volume and assortment (such as brands, appellations, typologies) mainly because of sparkling Prosecco consumption. We investigate the repeated purchase behavior of sparkling wines in two years within the supermarket channel through scanner data collected from a consumer panel. We propose a Hidden Markov Model to analyze these data, assuming an unobservable process to capture consum- ers’ preferences and allowing us to consider purchases sparsity over time. We consider multi- variate responses defining types of purchases, namely price, appellation, and sugar content. Customers’ covariates influence the initial and transition probabilities of the latent process. We identify five market segments, and we track their evolution over time. One segment includes Prosecco-oriented consumers, and we show that loyalty to Prosecco changes strongly over time according to the region of residence, income, and family type. The findings improve the understanding of the market and may provide evidence to design successful marketing strategies.

Willingness to Pay for Wine Bullshit: Some New Estimates

Kevin W. Capehart
Pages: 260-282
Abstract

As part of a classic article in this journal, Richard Quandt identified 123 wine descriptors that he deemed to be bullshit. In this paper, I examine whether wine consumers are willing to pay any more (or less) for wine if it is described by one of those “bullshit” descriptors. I use three methods to examine that. The first method involves applying a hedonic regression to a dataset of prices and expert descriptions for about 50,000 wines. The second method involves applying a match- ing estimator to the same dataset. The third method involves a stated-preference survey of about 500 wine consumers. The three methods suggest that for most of the descriptors Quandt deemed to be bullshit, most consumers’ marginal willingness to pay for a descriptor is zero or near-zero. Yet, for some of the descriptors, some consumers do seem to have a non-zero marginal willing- ness to pay, perhaps because the descriptors shape a consumer’s subjective experience or because they signal objective aspects of wine.

Divestiture and Its Market Reaction in a Consolidating Industry: The Global Brewing Industry

Ludwig Erl & Florian Kiesel
Pages: 239-259
Abstract

This study provides a perspective on the market performance of divestitures in the global brewing industry. In 2018, the five largest players accounted for 60% of the global beer volume. We analyze to what extent the capital market values divestitures in an industry where players usually seek efficiency gains and growth through mergers and acquisitions. Based on a sample of 61 divestiture intent announcements in the period from 1999–2018, this study shows that publicly listed brewing groups experience significant positive abnormal returns of about 1.4%. We measure the influential effect of success determinants concerning the underlying industry, the divested business, the divestiture structure, and the divestor itself.

Consumer Stigma and the Reputation Trap Hypothesis: An In-Store Experiment with Colorado Wines

Marco Costanigro & Becca B.R. Jablonski
Pages: 210–230
Abstract

We conducted an in-store experiment to test the hypothesis that Colorado wines may suffer from reputational stigma. The context relates to marketing challenges faced by novel wine regions entering the competitive retail environment, even in a local context, and the possibility of being stuck in a “bad reputation trap.” Adopting a 2×2 design where we varied region of production (Colorado vs. California) and grape variety (familiar vs. unfamiliar), we adminis- tered a between-subject information treatment that revealed the origin of production to only half of the participants. We measured taste perceptions using Likert scales, and we elicited val- uation via a multiple price listing. Our results are consistent with the presence of stigma against wines produced in Colorado. In the discussion, we draw from the literature on stigmatized markets to suggest plausible strategies to remove or avoid stigma.L1, L15, Q1, Q13

On Fine Wine Pricing across Different Trading Venues

Paweł Oleksy, Marcin Czupryna & Michał Jakubczyk
Pages: 189–209
Abstract

This article examines how selected attributes of Bordeaux fine wines (producer, vintage, quality, bottle size, case, flaws, and transaction volume) affect prices in three types of trading venues: auc- tions, electronic exchange, and the over-the-counter (OTC) market. The findings indicate a price differentiation across the venues. Wine aging leads to relatively higher prices at auctions than on the electronic exchange or the OTC. There is a nearly linear relationship between prices and wine ratings, the strongest of which is found in the case of auctions. The bottle size effect is mostly positive for supersized formats and is the strongest on an electronic exchange and the weakest at auctions. The transaction volume negatively affects wine prices in all the trading venues. The simulation results facilitate the construction of more realistic trading models and may help traders make more informed decisions on the choice of a trading venue, depending on the wine characteristics.

Reputation and Advertising of Collective Brand Members in the Wine Industry: The Moderating Role of Market Share

Ricardo Sellers-Rubio, Francisco Mas-Ruiz & Franco Sancho-Esper
Pages: 169–188
Abstract

This paper analyzes the nonlinear relationship between the advertising investment and repu- tation of collective brand members in an experience goods industry, as well as the moderating role of their market share within the collective brand. The central assumption is that the quality reputation of collective brand members has a positive effect on their advertising invest- ment until a reputation threshold is reached, after which the effect on advertising investment becomes negative. This change in the slope is explained by the information sets (firm reputa- tion and collective reputation) used by consumers to reduce uncertainty, which leads to a weaker motivation for the firm to invest in advertising. In addition, scale economies of adver- tising mean that the market share of collective brand members negatively moderates the cur- vilinear relationship between quality reputation and advertising investment. The results for a sample of 176 companies in a Spanish experience goods industry (i.e., winemaking) between 2004 and 2014 show an inverted U-shaped relationship between the advertising investment and reputation of collective brand members. The results also show that market share nega- tively moderates this curvilinear relationship.

Did Wine Consumption Change During the COVID-19 Lockdown in France, Italy, Spain, and Portugal?

Abstract

This article documents how the COVID-19 crisis has affected the drinking behavior of Latin European wine consumers. Using a large online survey conducted during the first lockdown in France, Italy, Portugal, and Spain (n = 7,324 individuals), we reconstruct the purchasing and consumption patterns of the respondents. The number of people who maintained their wine consumption frequency is significantly higher than those who increased or decreased their con- sumption. Wine consumption frequency held up better than other types of alcohol (beer and spirits). We analyze heterogeneities among countries and individuals by employing the Marascuilo procedure and an ordered logit model. The latter identifies the impact of demo- graphic, commercial, and psychosocial factors on wine consumption frequency. The results shed light on changes in wine consumer behavior during the first lockdown and consider pos- sible post-lockdown trends that could be useful to industry players.

COVID-19 and Global Beverage Markets: Implications for Wine

Glyn Wittwer & Kym Anderson
Pages: 117–130
Full Text PDF
Abstract

This article provides an empirical case study of the impacts of the COVID-19 pandemic on global beverage markets, particularly the wine sector. Both international trade and domestic sales have been adversely affected by temporary shifts away from on-premise sales by social distancing measures and self-isolation that led to the closure of restaurants, bars, and clubs, plus declines in international travel and tourism. Partly offsetting this has been a boost to off-premise and direct e-commerce sales. We first estimate those impacts in 2020 and their expected partial recovery in 2021 using a new model of global beverage markets. Further recent disruption to the global wine trade has been the imposition by China in late 2020 of prohibitive tariffs on its imports of bottled wine from Australia. Its diversionary and trade- reducing effects are compared with those due to COVID-19.

Introduction to the Issue

Introduction

This issue of the Journal of Wine Economics opens with two COVID-related papers.

First, Glyn Wittwer and Kym Anderson analyze “COVID-19 and Global Beverage Markets: Implications for Wine” (Wittwer and Anderson, 2021). The authors employ a model of global beverage markets to simulate the respective effects of the COVID-19 pandemic (Wittwer and Anderson, 2020). They find that both international trade and domestic sales have been adversely affected by temporary shifts away from on-premise sales. These losses have partially been offset by gains in off-premise and direct e-commerce sales. “Further recent disruption to the global wine trade has been the imposition by China in late 2020 of prohibitive tariffs on its imports of bottled wine from Australia. Its diversionary and trade-reducing effects are compared with those due to COVID-19” (Wittwer and Anderson, 2021, p. 117).

Magalie Dubois and collaborators shed light on the question, “Did Wine Consumption Change during the COVID-19 Lockdown in France, Italy, Spain, and Portugal?” (Dubois et al. 2021). Drawing on an online survey of more than 7,300 individuals conducted during the first lockdown phase, the authors analyze purchasing and consumption patterns. They find that more people reduced their wine consumption frequency than maintained or increased it. Further analyses highlight various aspects of heterogeneity among countries and individuals and their determinants.

In “Reputation and Advertising of Collective Brand Members in the Wine Industry: The Moderating Role of Market Share,” Ricardo Sellers-Rubio, Francisco Mas-Ruiz, and Franco Sancho-Esper analyze the nonlinear relationship between advertising investments and reputation of collective brand members (Sellers-Rubio, Mas-Ruiz, and Sancho-Esper, 2021). They draw on a sample of 176 Spanish wineries and show that the quality reputation of collective brand members has a positive effect on their advertising investment until a reputation threshold is reached. In addition, scale economies of advertising mean that the market share of collective brand members negatively moderates the curvilinear relationship between quality reputation and advertising investments.

In their paper entitled “On Fine Wine Pricing across Different Trading Venues,” Paweł Oleksy, Marcin Czupryna, and Michał Jakubczyk shed light on how selected attributes of fine Bordeaux wines affect prices in three types of trading venues:

auctions, electronic exchanges, and over-the-counter markets (Oleksy, Czupryna, and Jakubczyk, 2021). Their findings suggest that the price-impact of various char- acteristics varies across trading venues. For instance, while auctions pay a substantial premium for a wine’s age, the marginal price effects of age are lower at electronic exchanges and over-the-counter markets. Similarly, the (positive) bottle size effect is strongest in electronic exchange markets and weakest at auctions.

The last paper of this issue, entitled “Consumer Stigma and the Reputation Trap Hypothesis: An In-Store Experiment with Colorado Wines,” is by Marco Costanigro and Becca B.R. Jablonski. The authors conduct an in-store experiment to test the hypothesis that Colorado wines may be in a “bad reputation trap.” Based on a 2×2 design where they varied the production region (Colorado vs. California) and grape variety (familiar vs. unfamiliar), they revealed the origin of production to only half of the participants (Costanigro and Jablonski, 2021). The authors measure taste perceptions on Likert scales and elicit valuations via a multi- ple price listing. “Our results are consistent with the presence of stigma against wines produced in Colorado. In the discussion, we draw from the literature on stigmatized markets to suggest plausible strategies to remove or avoid stigma” (p. 210).
