Moreover, typicity and authenticity of a wine are defining conditions under conditions of fierce intemational competition to guarantee success of wine. There were concerns for determining areas with designation of origin from a vineyard that will produce quality wines, but the purpose of this study is to delimit the level of a vineyard small area that can ensure the achievement of a certain type of wine, a quality required by consumers. The research was made during 2006-2008 and revealed that the production of quality grapes and are influenced by different factors such as genetic, environmental and technological acting in complex. This is a first attempt to study characterize the concept of ＂terroir＂, as applied in the Copou vineyard from lasi county and provides information on the behavior of two varieties of grapes for wine： Feteasca Regala and Muscat Ottonel. Depending on the purpose, observations and calculations have found the influence of soil characteristics on several biochemical parameters and productive at varieties of Feteasca Regala and Muscat Ottonel （soluble carbohydrate content, total acidity, the average yield of grapes） for the purpose of knowledge than a more detailed wine center in northeast of Romania. The results of this study can be used to determine with precision small areas crop at the parcel that will produce quality wines.展开更多

These factors influence the biosynthetic activities of plants and their phenology, promoting biodiversity and the qualitative predispositions of grapes and wine. South Tyrol is one of the smallest wine-growing regions in Italy, but owing to its position amid the Alps, it is also one of the most multifaceted, a region of wide geographical diversity and remarkable ecological range, hosting a concentration of many different vine varieties and high quality wines. This applied territorial research investigates the particular environmental circumstances that favour this case. A data set describing approximately 26,000 vineyards and 5450 hectares has been employed to evaluate 18 subzones of wines and vines selected from 86 new geographical units defined within the DOC wine region. A new environmental mapping scheme called VHTG is proposed, based on the ecological indicators of grape variety, altitude, topoclimate and the geopedology of the vineyards. Using the VHTG method analyses, the comparisons between the territories of origin and their vine varieties can be rendered simpler and more direct, and it can distinguish the most suitable ecological conditions of wine production zones. It is now possible to examine more in detail the land suitability of the different cultivars, defined by the use of the ecological indicators summarized in the VHTG method. White grape varieties such as Sylvaner and Veltliner prefer high altitudes between 600 m and 900 m, a very high solar radiation SRI index from 80 to 95, and acidic sandy soils of silicate minerals. The most complete and intense tannic structure of regional Pinot Noir correlates to quite clayey soils with dolomite mineral, slightly alkaline, on vineyards at altitudes between 350 m and 410 m, with rather low SRI index from 60 to 75. Similar geopedological conditions favour Gewürztraminer, which, however, requests SRI from 75 to 85. Merlot and Cabernet vines are best expressed in the hottest regional sub-zones, on moderately clayey subalkaline soils at 250 - 350 m of altitudes and SRI around 80. The indigenous red grape variety Lagrein is mostly localized on alluvial cone at altitudes under 350 m, on soft and ventilated acid sands with volcanic silicate minerals.展开更多
