Effect of row direction in the upper part of the hillside vineyard of Somló, Hungary


Hillside vineyards have a great potential to produce world class wines. The unique microclimate lead to the production of rich, flavory wines. However site development needs land clearing, rock removal, terracing, engineered water collecting drainage system. Because of the very high cost of establishment every part of the plantation needs to be very carefully planned, designed and established. Row direction has a pronounced effect on sunlight interception. The amounts of direct light are absorbed by the canopy is influenced by the row direction. Commonly known that greater amounts of light absorbed by the canopy the mid-morning and mid-afternoon in rows directed north-south compared to east –west. But information on the effects of row direction on the fruit quality of grapevines are limited. Therefore we established an experiment on hill Somló to determine if row direction has role to improve the quality or not. We have 24 % less yield, higher sugar content, lower acid content in row direction east-west compared to the north-south in 2006. Similar results were obtained in 2007 as well. The catechin contents differed statistically only among other poliphenols between the row directions. The wine analysis and organoleptical evaluation showed that the east-west oriented rows produced better quality of wine in 2006. We have very extreme weather conditions in 2007 in July and August therefore we have not got the same picture in 2007 like in 2006. Even if we have only two year results the clear influence of row direction pictured on the quality of the yield.

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.
