Characterization of the Wine Grape Thermohydrological Conditions in the Tropical Brazilian Growing Region: Long-Term and Future Assessments Repositório Alice
TEIXEIRA, A. H. de C.; TONIETTO, J.; PEREIRA, G. E.; HERNANDEZ, F. B. T..
Over the last years, Brazil has appeared among the newtropicalwine producing countries.Thejoined effect of rising air temperature and decreasing precipitation makes it important to quantify the trend of the thermohydrological conditions of the commercial vineyards. The aims of the current research were to classify and delimit these conditions for the winemaking processes under different time scenarios in the BrazilianNortheastern region. Bioclimatic indicatorswere used togetherwith long-termweather data and projections of the IPCC emission scenarios under simulated pruning dates.The results showed that decreasing of precipitation should be good for wine production when irrigation water is available, but rising air temperature will affect the wine quality...

DO MORE EXPENSIVE WINES TASTE BETTER? EVIDENCE FROM A LARGE SAMPLE OF BLIND TASTINGS AgEcon
Goldstein, Robin; Almenberg, Johan; Dreber, Anna; Emerson, John W.; Herschkowitsch, Alexis; Katz, Jacob.
Individuals who are unaware of the price do not derive more enjoyment from more expensive wine. In a sample of more than 6,000 blind tastings, we find that the correlation between price and overall rating is small and negative, suggesting that individuals on average enjoy more expensive wines slightly less. For individuals with wine training, however, we find indications of a positive relationship between price and enjoyment. Our results are robust to the inclusion of individual fixed effects, and are not driven by outliers: when omitting the top and bottom deciles of the price distribution, our qualitative results are strengthened, and the statistical significance is improved further. Our results indicate that both the prices of wines and wine...

Does Product Diversity Signal Bargains in Australian Wine? AgEcon
Horowitz, Ira; Lockshin, Larry.
The residuals from a set of linear regression equations built to explain the quality of a bottle of Australian wine via eight quality signals are examined to determine whether there is any relationship between their signs for individual producers and the diversity of their offerings. Product diversity is found to be a fault-ridden signal of a quality-bargain, which we define as a bottle of wine whose quality rating exceeds its regression-based expectation. Indeed, to the extent that the signal does impart useful information, the message would be that consumers are less likely to get their money's worth the greater is the diversity of the producer's offerings.

Effects de l'application d'acide gibbérellique (GA3) sur la qualité de raisins et de vins produits en climat tropical au Nord-Est du Brésil. Repositório Alice
COSTA, A. L. C.; SOARES, J. M.; PEREIRA, G. E.; SANTOS, J..
The honeydew moth Cryptoblabes gnidiella is the main problem for the wineries in the Northeast of the Brazil, because it attacks the bunch and reduces the quality of the grapes and the wines. In order to stretch out the bunch to facilitate the penetration of the insecticides, it was used gibberellic acid. Six treatments with different concentrations and different dates of application, and the control were compared. The bunches are compact, characteristic of the "Syrah" grapes in the region. The grape berries were analysed at harvest and wines were made by microvinifications. The grape berries showed different qualitative characteristics, as berry weight, number of berries. °Brix, total acidity and heterogeneity of the maturation. The microvinifications...

How do consumers use signals to assess quality? AgEcon
Gergaud, Olivier; Livat, Florine.
This article analyzes the way some 6,000 European wine consumers, both connoisseurs and non-connoisseurs, use a set of available signals (price, umbrella branding, goodwill, past consumption) to assess the quality of Bordeaux wines where price is the main source of information on quality. Connoisseurs use this signal less intensively than on connoisseurs. Price represents a substitute for umbrella branding where consumers are not aware of who is beneath this umbrella, and where this signal is thus of no help to them. This could explain why such wines tend nowadays to lose market share in favor of branded wines that are easier to evaluate.

Influência do uso de chip de carvalho francês na composição físico-química e colorimétrica de vinho tinto "Syrah". Repositório Alice
SILVA, I. S.; NOGUEIRA, E. T.; BARROS, A. P. A.; SANTOS, R. G. de B.; SILVA, L. F. da; BIASOTO, A. C. T..
A região do Vale do Submédio São Francisco (VSSF) é a segunda maior região produtora de vinhos elaborados com as cultivares Vitis vinifera do país, na qual a variedade Syrah destaca-se como a mais utilizada na região para a elaboração de vinhos tintos. Os vinhos elaborados com essa cultivar dispõem de alta capacidade de amadurecimento, para isso, avaliou-se o efeito da utilização de chips de carvalho francês de média tostagem na composição físico-química e colorimétrica de vinho tinto ?Syrah? elaborado no VSSF. Foram testados dois tratamentos, um de controle (sem utilização de chip) e o outro utilizando chip de carvalho francês de média tostagem (6g.L-1). Os parâmetros avaliados foram: pH, acidez total e volátil, açúcares redutores, densidade, dióxido de...

Natural endowments, production technologies, and the quality of wines in Bordeaux. Is it possible to produce wine on paved roads? AgEcon
Gergaud, Olivier; Ginsburgh, Victor.
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.

Predicting the quality and prices of Bordeaux wines AgEcon
Ashenfelter, Orley.
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.

Quality evaluation of grapes for mechanical harvest using vis NIR spectroscopy CIGR Journal
Vallone, Mariangela; Alleri, Maria; Bono, Filippa; Catania, Pietro.
Mechanical harvest of grapes is one of the operations that mostly influence the quality of the future wine. The shaking frequency of the harvesting machine is usually adjusted on the basis of the grape berry characteristics in order to limit grape juice production that is a potential cause of uncontrolled fermentations. These evaluations usually require time, personnel and laboratory analyses. The introduction of a vis NIR system to rapidly and reliably evaluate the berry properties in field before mechanical harvest could be a good alternative. The aim of this study was to evaluate the feasibility of applying vis NIR spectroscopy as a non-destructive technique on grapes cv. Syrah and Chardonnay to predict pedicel detachment force, pH and total soluble...

The impact of the wine industry on hotels and restaurants in Walla Walla AgEcon
Storchmann, Karl.
Walla Walla enjoys the fastest growing wine industry in the State of Washington, if not in the whole U.S. This paper examines the impact of this extraordinary growth on the revenue of regional 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. Less than 17% of all restaurant and approximately 40% of all hotel revenue is tied to the wine cluster (2007). However, regional reputation is short-living and needs to be constantly re-earned.
