Evaluation of phenolic compounds content and in vitro antioxidant activity of red wines produced from Vitis labrusca grapes Ciênc. Tecnol. Aliment.
Lima,Daniel Braga de; Agustini,Bruna Carla; Silva,Eliz Guimarães da; Gaensly,Fernanda; Cordeiro,Rodrigo Becker; Fávero,Maria Luiza Drechsel; Brand,Debora; Maraschin,Marcelo; Bonfim,Tania Maria Bordin.
Wine production in the northern Curitiba, Paraná, Brazil, specifically the communes of Colombo and Almirante Tamandaré, is based mainly on the utilization of Vitis labrusca grapes var. Bordô (Ives). Total sugar content, pH, and total acidity were analyzed in red wine samples from 2007 and 2008 vintages following official methods of analysis. Moreover, total phenolic, flavonoid, and tannin contents were analyzed by colorimetric methodologies and the antioxidant activity was determined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical methodology. Phenolic compounds were identified by high performance liquid chromatography. The total phenolic content of wine samples presented concentrations varying between 1582.35 and 2896.08 mg gallic acid.L-1 since...

Feasibility of a Co-operative Winery AgEcon
Kenkel, Philip L.; Holcomb, Rodney B.; Hill, Amanda.
The number of operating wineries in the United States has doubled during the past decade. Most of this growth has been due to a large number of entrepreneurial landowners developing their own small acreage vineyards and trying to branch into winemaking. However, wineries are capital-intensive enterprises which require high initial investment and experience lagged cash flow associated with the time between the purchase of grapes and initial wine sales. Additionally, the availability of local grape production often limits the production capabilities of an entrepreneur’s small winery. As a result, some vineyard owners consider establishing co-operative wineries. This paper describes a feasibility assessment tool developed to assist vineyard owners in...

Solvency and Performance of French Wineries in Times of Declining Sales: Co‐operatives and Corporations AgEcon
Declerck, Francis; Viviani, Jean-Laurent.
The paper assesses the ability of French wineries to prevail over the crisis of French wine in the years 2000. Corporations are distinguished from co‐operatives: Over the 2000‐2006 period in spite of sales fluctuations, French wineries did not increase their financial debt level substantially. Such result supports the traditional static trade‐off theory (TOT). Co‐operatives were able to absorb part of the impact of the wine crisis at the expense of their members, in increasing account payables to member. Corporations have not increased trade account payables to vine growers. In the mid‐2000s, the French wine crisis has not been strong enough to shake the financial structure of cooperatives and corporations. But co‐operatives look more affected. However,...
