A Hedonic Pricing Model for German Wine AgEcon
Schamel, Guenter.
We develop a hedonic pricing model for German quality wine. Quality indicators for 4,141 wines are sensory awards received at the annual German wine competition and the legally required quality category as well as a set of control variables including regional origin, color, style, and their age at the time of judging. The data confirms that sensory quality awards have a significant and positive price impact. Moreover, we estimate significant relative differences between quality categories, growing regions and most of the control variables.

A Methodology for Evaluating How Product Characteristics Impact Choice in Retail Settings with Many Zero Observations: An Application to Restaurant Wine Purchase AgEcon
Durham, Catherine A.; Pardoe, Iain; Vega-H, Esteban.
An approach is developed to examine the impact of product characteristics on choice using a quantity-dependent hedonic model with retail panel data. Since panel data for individual products from retail settings can include a large number of zero sales, a modification of the zero-inflated Poisson (ZIP) regression model is proposed for estimation. Results for this model compare favorably to results for alternative hurdle and negative binomial models. An application of this methodology to restaurant wine sales produces useful results regarding sensory characteristics, price, and origin/varietal information.

A peculiar behaviour for cell death induced by weak carboxylic acids in the wine spoilage yeast Zygosaccharomyces bailii IPB - Escola Superior Agrária
Estevinho, Leticia M.; Côrte-Real, Manuela; Leão, Cecília.
In glucose-grown cells of Zygosaccharomyces bailii, ISA 1307 acetic acid and other carboxylic acids enhanced death. The effects were much lower than those described for Saccharomyces cerevisiae, being only detectable at higher acid concentrations. In Z. bailii, acetic acid and other weak acids also induced intracellular acidification, but this effect was less pronounced than that of death and no relationship was found with death enhancement. The results suggested that in Z. bailii, unlike S. cerevisiae, intracellular acidification induced by weak acids is less pronounced and appears not to have a significant role in death at the temperature range used.

Alcohol and atherosclerosis Anais da ABC (AABC)
DA LUZ,PROTASIO L.; COIMBRA,SILMARA R..
Atherosclerosis is manifested as coronary artery disease (CAD), ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is...

Alcohol and Mortality from All Causes Biol. Res.
RENAUD,SERGE; LANZMANN-PETITHORY,DOMINIQUE; GUEGUEN,RENÉ; CONARD,PASCALE.
A large number of prospective studies have observed an inverse relationship between a moderate intake of alcohol and coronary heart disease morbidity and mortality. Concerning death from all-causes, results are not unanimous. Alcohol intake was associated with a protection of all-cause mortality in England and USA physicians and the large study of the American Cancer Society. None of these studies separated the effects of different alcoholic beverages. In our prospective studies in France on 35 000 middle-aged men, we observed that only wine at moderate intake, was associated with a protective effect on all-cause mortality. The reason was that in addition to the known effect on cardiovascular diseases, a very moderate intake of wine, protected also from...

Alcohol, Wine and Platelet Function Biol. Res.
RUF,JEAN-CLAUDE.
Epidemiological studies have demonstrated an inverse correlation between moderate wine and alcohol consumption and morbidity and mortality from coronary heart disease. The protective effect has been associated with an increase in the plasma level of HDL cholesterol, as it is well recognized that plasma HDL is inversely correlated with CHD. In addition, it has become evident that blood platelets contribute to the rate of development of atherosclerosis and CHD through several mechanisms. In recent studies it has been shown that the level of HDL cholesterol can explain only 50 % of the protective effect of alcoholic beverages; the other 50 % may be partly related to a decrease in platelet activity. This anti-platelet activity of wine is explained by ethanol...

An experimental study of wine consumers’ willingness to pay for environmental characteristics AgEcon
Bazoche, P.; Deola, C.; Soler, Louis-Georges.
The reduction of pesticides use is becoming a priority for the public authorities in many countries. We conducted an experiment with wine consumers to see whether end-consumers value the dissemination of information about environmentally-friendly production practices. The experiment was devised to (i) evaluate whether there is a premium for environmentally-friendly wines, (ii) determine whether or not consumers are sensitive to label owners who implement and guarantee the environmental actions, (iii) and assess the impact of public messages about the consequences of pesticide use. Some 139 participants were divided randomly into two groups. One group had no specific information about the current state of pesticide use in farming. The other group was given...

Analysing Wine Demand With Artificial Neural Networks AgEcon
Gerolimetto, M.; Mauracher, Christine; Procidano, I..
In this paper we analyse wine demand in Italy using microdata. Instead of estimating a traditional parametric model (like AIDS) we employed artificial neural networks (ANN) and evaluate the elasticities using two different methods, specific for the non parametric framework. We compared the performances of the two methods to estimate elasticities and put in evidence the relevance of some demographic variables together with the usual economic ones, explaining the consumer's behaviour.

Analysis of major metallic elements in Chilean wines by atomic absorption spectroscopy Ciencia e Investigación Agraria
Laurie,V. Felipe; Villagra,Evelyn; Tapia,Jaime; Sarkis,Jorge E. S; Hortellani,Marcos A.
A set of 75 wine samples from seven of the major wine producing regions in Chile were analyzed with flame atomic absorption spectroscopy (AAS) to determine their content of major metallic elements (K, Mg, Ca, Na, Fe and Zn). The results obtained were further analyzed with principal component analysis (PCA) in an attempt to loosely discriminate these wines according to grape type and geographical origin. The metal concentrations measured were within normal ranges, according to previously published data from other wine producing countries. Multivariate statistics allowed the possibility to reasonably discriminate between red and white wines, and to show a distinctive pattern of Na concentration, with higher total contents for the wines produced in the...

BUBBLES IN PRICES OF EXHAUSTIBLE RESOURCES AgEcon
Jovanovic, Boyan.
Aside from the equilibrium that Hotelling (1931) displayed, his model of non-renewable resources also contains a continuum of bubble equilibria. In all the equilibria the price of the resource rises at the rate of interest. In a bubble equilibrium, however, the consumption of the resource peters out, and a positive fraction of the original stock continues to be traded forever. And that may well be happening in the market for high-end Bordeaux wines.

CATCHING-UP TRAJECTORIES IN THE WINE SECTOR: A COMPARATIVE STUDY OF CHILE, ITALY AND SOUTH AFRICA AgEcon
Cusmano, Lucia; Morrison, Andrea; Rabellotti, Roberta.
From a development perspective an investigation of the changes that have occurred in the wine industry is of particular interest because it provides evidence on how emerging economies have been able to acquire significant shares of the international market in a dynamic sector. Based on novel empirical evidence as well as secondary sources, this paper shows that emerging countries with diverse institutional models and innovation strategies, have been driving the process of technological modernization and product standardization. Newcomers in the wine sector have responded particularly effectively to changes in consumption habits, and in aligning emerging scientific approaches with institutional building efforts and successful marketing strategies.

Characterization of grapes and wines of Syrah growing during the autumn-winter season in different viticultural zones of the Brazilian Southeast. Repositório Alice
MOTA, R. V. da; SOUZA, C. R. de; PEREIRA, G. E.; DAL'OSTO, M. C.; CORREA, L. C.; DIAS, F. A. N.; PIMENTEL, R. M. de A.; TAVARES, M. C.; REGINA, M. de A..
Double pruning management has allowed harvesting good quality wine grapes during the winter season in the Brazilian southeast. Syrah cultivar showed the best response to the modification of grapevine cycle with good maturation and acceptable productivity indices. As a new winegrowing region, little is known about the terroir effects on the composition of Syrah berries and wines. This study was carried out with Syrah vines grafted on 1103P grown in commercial vineyards established in four southeast zones of Brazil: Espirito Santo do Pinhal at 871 m height, Itobi at 811 m, Três Corações at 993 m and Caldas at 1150 m. The vines were trained on vertical shoot position and pruned in January to harvest grapes in the winter season. The highest yield was obtained...

PEREIRA, G. E.; ARAÚJO, A. J. B.; SANTOS, J. de O.; OLIVEIRA, S. V.; NASCIMENTO, R. L.; QUINTINO, C.; VANDERLINDE, R.; LIMA, L. L. A..
Traditional winegrowing areas are located in temperate climate zones and allow to produce grapes only once per year. Tropical wines have been elaborated in India, Thailand, Venezuela and Brazil and present another kind of viticulture, as compared with countries located in temperate climate zones. Northeast of Brazil started wine production twenty six years ago. This region vines can produce two or three crops per year, depending of the cycle of different cultivars. Harvests can be scaled throughout the year, mainly between May and December, corresponding to the dry season. Red, white, rosé and sparkling wines are being elaborated in the region. The objective of this work was to determine the physico-chemical and aromatic characteristics of some tropical...

Cinnamic acid, ethanol and temperature interaction on coumarate decarboxylase activity and the relative expression of the putative cd gene in D. bruxellensis Electron. J. Biotechnol.
Ganga,María Angélica; Salinas,Francisco; Ravanal,Cristina; García,Verónica; Carrasco,Carolina; Martínez,Claudio; Saavedra,Jorge.
Dekkera bruxellensis is one of the main contaminating yeasts in wine due to its ability to metabolize cinnamic acids into volatile phenols. This yeast metabolizes p-coumaric acid into 4-vinylphenol through a coumarate decarboxylase (CD) and then transforms it into to 4-ethylphenol (EF) through a vinylphenol reductase. In this work we investigated the influence of the interaction between the concentration of p-coumaric acid, ferulic acid and ethanol as well as growth temperature on the production of CD activity and the expression of a putative gene that codes for this enzymatic activity. For this, a Box Behnken experimental design was used. The concentration of p-coumaric acid (5-26 ppm) and ferulic acid (3-9 ppm) alone did not show any significant effect...
