The influence of climate change on the potassium, pH and total acidity of wines
Over recent decades, the alcohol concentration of wines increased due to the higher sugar concentration of grapes when harvested. This also led to an increase in pH and a decrease in the total acid concentrations of wines.

Winery wastewater for irrigation (Part 3): Vineyard catch- and cover crop responses
During wine production, wineries produce large volumes of poor-quality wastewater. This wastewater can be used for irrigation, but this delivers substantial amounts of elements to the soil.

In-field fractional use of winery wastewater with raw water (Part 2): Irrigation application, water quality and nutrient load
The primary objective of this project was to assess the fitness for use of winery wastewater for irrigation of different soil types with varying rainfall quantities and leaching levels on vineyard performance in terms of yield and quality under field conditions.

In-field fractional use of winery wastewater with raw water (Part 3): Soil responses
The aim of this study was to determine the effect of in-field fractional use of winery wastewater with raw water for vineyard irrigation on the chemical status of different soils to assess the fitness for use of winery wastewater for irrigation of different soil types with varying rainfall.
