Última 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...

Ano: 2013 URL: http://www.infoteca.cnptia.embrapa.br/infoteca/handle/doc/991761 Desenvolvimento de metodologia para detecção e quantificação de compostos fenólicos em vinhos. Infoteca-e CORREA, L. C.; RYBKA, A. C. P.; BIASOTO, A. C. T.; SILVA, P. T. de S. e; PEREIRA, G. E.. Com este trabalho, objetivou-se desenvolver um método cromatográfico para a quantificação de compostos fenólicos em vinhos brancos e tintos por cromatografia líquida de alta eficiência. Para a validação em amostras, foram selecionados dez vinhos. Foram utilizados 25 padrões de compostos fenólicos. A separação dos compostos foi realizada utilizando-se simultaneamente os detectores de arranjos de fotodiodos e fluorescência. As fases móveis utilizadas foram: solução de dihidrogenofosfato fosfato de potássio em água ultrapura com pH ajustado para 2,05; metanol e acetonitrila e como fase estacionária foi utilizada coluna C18 (150x4,60 mm, 3μm). A seletividade foi confirmada através dos tempos de retenção e dos espectros de absorção dos padrões...

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.

Ano: 2007 URL: http://purl.umn.edu/37296 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.

Ano: 2007 URL: http://purl.umn.edu/37297 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.

Ano: 2006 URL: http://purl.umn.edu/8204 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... Tipo: Working or Discussion Paper Palavras-chave: Wine quality; Wire tasting; Wine prices; Demand and Price Analysis. Ano: 2008 URL: http://purl.umn.edu/37328 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.

Ano: 2008 URL: http://purl.umn.edu/37358 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.
