Abstract

The paper analyzed grape quality for 11 Vine types at Bujoru Vineyard, based on the analysis of 22 climate factors. We concluded that the year 2009 was an extremely dry year compared to 2007. The useful thermal balance, sunstroke, average temperature in August, air humidity, bioactive period, bioclimatic index and oenoclimatic coefficient were higher, while global and active thermal balance, average rainfalls during the vegetation period, average temperature in July, August and September, minimum air temperature, average temperature in the 1st and 2nd decades, nebulousness, number of days with maximum temperatures over 30 degrees, hydrothermic index registered lower levels in 2009. As a result, sugar content decreased while acidity, the weight of 100 berries and grape weight have grown up for almost all vine types as shown in Tab.1. Point Method allowed to establish the hierarchy of Vine varieties, which in the decreasing order is: Hamburg Muscat, șarba, Coarnă neagră, Babească neagră, Chasselas doré, Fetească neagră, Fetească albă, Aligoté, Fetească regală, Merlot, Cabernet Savignon.
