Productivity, quality, and thermal needs of the Piedirosso vine: four years of observations

Abstract

The effects of temperature on cv Piedirosso, indigenous of the Campania region (South of Italy), were tested in order to study its possible influence on grapevine and to discover how to optimize the qualitative expression of the cultivar. Relationships between evolution of the main must components, berry weight, and heat requirement of the cv Piedirosso were studied. The cv Piedirosso showed itself to be suitable to the area tested. We evidenced a reasonable agreement of the model of Amerine and Winkler’s estimation as to the thermal needs of cv Piedirosso. The heat requirement of the cultivar was determined in 1750-1850 degrees/day (DD) to obtain a sugar content of 21-22 °Brix, a pH of 3.10-3.20 and a titratable acidity of 8-9 g/l; to obtain a higher sugar content of musts (23-24 °Brix, pH of 3.2-3.3, titratable acidity of 8-9 g/l) the thermal needs is 1800-1900 DD.

Relationship between terroir and acidity for the red wine grape cultivar Malbec N or Cot N (Vitis vinifera L.) in AOC “Cahors” and “Côtes du Frontonnais “

L’étude préliminaire, réalisée sur les principaux cépages de la région Midi-Pyrénées, a montré que le Cot N possédait des teneurs en acide tartrique dans les moûts et les vins plus élevées que celles des cépages Négrette N, Tannat N, Duras N et Fer Servadou N.

Vineyard Landscape in Vale dos Vinhedos: Pressure and Protection

The region with Origin Indication Vale dos Vinhedos (IPVV) is located in the cities of Bento Gonçalves, Garibaldi and Monte Belo do Sul. It was established in November 2002, through an act of Instituto Nacional de Propriedade Industrial, according to Resolução INPI Nº. 75, of 2000, and Law Nº. 9.279 of 1996. The changes on the grape growing and wine making in the last 15 years, with the expansion of grapevines Vitis viníferas cultivation, the installation of several modern family wine companies, making wine with competitive quality, among other aspects, have enabled the implementation of concepts of Geographical Indications.

A NEW SPECIFIC LINEAGE OF OENOCOCCUS OENI IN COGNAC APPELLATION WINES

Oenococcus oeni is the main lactic acid bacteria (LAB) species which conducts the malolactic fermentation (MLF) in wine. During MLF, O. oeni converts malic acid into lactic acid, which modulates wine aroma composition leading to better balanced organoleptic properties. O. oeni is a highly specialized species only detected in environments containing alcohol such as wine, cider or kombucha. Genome analysis of more than 240 strains showed that they form at least 4 main phylogenetic lineages and several sublineages, which are associated with different beverages or types of wines.
