Evoluţia maturării strugurilor la soiurile: Pinot Noir, Riesling Italian şi Fetească Neagră în condiţiile centrului viticol Recaş

Abstract

The aim of this paper is to establish the optimal grapes harvesting moment in case of Pinot noir, Riesling Italian and Feteasca Neagra varieties.The establishment of the optimal harvesting moment is very important especially for wine grapes varieties. Grapes rippening period differes calendaristically speaking from a year to another and from a vineyard to another, given the climate conditions and this is the fact for which is necessary to monitorize rippening evolution in case of each variety. Researches were made in 2006 and 2007 in Recas viticultural center. In order to establish the optimal grapes harvesting period analyses were made concerning sugar content and acidity. Analyses were made from the begining of the rippening period until grapes technological maturity. Samples of grapes were taken from each variety. The chosen samples must be representative for each variety, so we take samples from the bottom, middle and top of the vine.
