Wines produced from biodynamically grown grapes have received increasing attention. Similar to organic agriculture, biodynamics eliminates synthetic chemical fertilizers and pesticides. The primary...
Water and nutrients exist together in close association because plant-available nutrient ions are dissolved in the soil solution and nutrient uptake by grapevines depends on water flow through the ...

Wine production has always been characterized by inconsistent harvest volumes from one year to the next. One of the challenges is to provide the professionals involved in crop estimation with a rel...
Stefano PONI Opening presentation of the 4th Enoforum SIVE, 12th-23d of March 2005
The relation between the quantity of grapes produced per vine (or per hectare) and the quality of the product obtained has always been the main focus in viticulture. The trend of the last ten years...

Many growers in the Niagara Peninsula of Ontario are reluctant to use canopy division to address high vigor in their vineyards. An alternative approach of delayed shoot thinning was explored. Pinot...
In the humid climates of the Eastern US, rainfall is erratic. The occurrence, duration and severity of drought stresses are not easy to predict. Do we have significant problems due to drought (sign...
The harvest of botrytized grapes displaying fungal or mouldy aromas is not a new phenomenon (1;2). However, over the last few years, several aromatic defects with a fungal, mouldy or earthy character
Growing vines for wine production presents a special challenge because of the effects of water supplied by irrigation. While necessary to obtain good yields, they should be moderate to avoid negati...

The anthocyanic composition of Tannat, Cabernet Sauvignon and Merlot red grapes and wines was studied in 2002 and 2003. The vineyards were located in the South of Uruguay, consisting of 4 Merlot, 4...
Four grapevine training systems (single curtain, vertical shoot-positioned, high bush, and short bush) were compared for their effects on physiological performance, yield, vegetative growth, and must
