Grapevine trunk disease greatly affects grapevines in terms of yield and productivity. Researchers investigated the effect of using curettage and regrafting as alternative solutions for managing Esca in existing vineyards…
Introduction: The production of wine involves a complex process that includes the growth of yeast and bacteria, which are responsible for the fermentation of grape juice into wine. However, the…
Abstract The impact of treated municipal wastewater (TMW) irrigation on soil and grapevines was assessed under field conditions in vineyards in the Coastal region of South Africa. Grapevines were irrigated…
Background of the study Cold stabilisation removes excessive L-tartaric acid natural ionic salts (potassium bitartrate: KHT, and to a lesser extent, calcium tartrate: CaT) from the wine. After fermentation but…
Background of the study Sparkling wines are produced in different regions worldwide. Their production involves different grape varieties associated with edaphoclimatic characteristics and different winemaking methods, which determine their specificities…
Background In vineyards, the under-vine area is managed to control vegetation growth and to reduce the competing effect of growing plants on vines and fruit development. Applied under-vine management methods…
Background and Aim Soil microbiota plays a significant role in plant development and health and appears to be a major component of certain forms of grapevine decline. A greenhouse experiment…
Abstract: The levels of varietal thiols and the role these compounds play in Colombard wine have not been investigated in detail. This study assessed the levels of the varietal thiols…
Abstract: In Mediterranean viticulture, climatic conditions are the main factors that determine grape composition and wine quality. Global warming is causing an increase in the accumulation of soluble solids in…
