Drought tolerance of different scion cultivars (Part 4): Vegetative growth and yield
The study aimed to assess grapevine vegetative and yield responses in an almost worst-case scenario, i.e. grapevines growing under dryland conditions in sandy loam soil in the Swartland region.
Drought tolerance of different scion cultivars (Part 3): Grapevine water status
the objective of the study was to assess the grapevine water status of selected reference and alternative scion cultivars under dryland conditions in the Swartland region. It must be noted that the study aimed to assess grapevine responses in an almost worst-case scenario, i.e. grapevines growing…
Drought tolerance of different scion cultivars (Part 2): Soil water status
The objective of the study was to assess the vegetative growth, yield and wine quality response of selected alternative and reference wine grape scion cultivars to dryland conditions in the Swartland region of South Africa.
Drought tolerance of different scion cultivars (Part 1): Introduction
The objective of the study was to assess the vegetative growth, yield and wine quality response of selected alternative and reference wine grape scion cultivars to dryland conditions in the Swartland region of South Africa.
19th AWITC, Adelaide, Australia (Part 3): McLaren Vale and Adelaide Hills bus tour highlights
The Australian Wine Industry Technical Conference, held every three years, also featured a Bus Tour Programme in 2025. Carolyn Howell did two of these bus tours on 18 July and 23 July.
19th AWITC, Adelaide, Australia (Part 2): Smoke taint in wine - perspectives from the Australian experience
There were 34 workshops presented at the 19th Australian Wine Industry Technical Conference held in Adelaide, South Australia, from 19 - 24 July 2025, with 1 061 workshop tickets sold. Two workshops were presented on aspects of smoke taint in wines, flash presentations in the Plenary sessions and…

Irrigation strategy and trellis system (Part 3): Juice and wine characteristics
The primary objectives of the study were to determine during what stage(s) Pinotage per se is sensitive to water deficits, the most suitable irrigation strategy when water restrictions are imposed during periodic droughts, and if more grapes can be produced with the same volume of irrigation water…
Irrigation strategy and trellis system (Part 2): Yield of Pinotage grapevines in the Breede River Valley region
The primary objectives of the study were to determine during what stage(s) Pinotage is sensitive to water deficits, the most suitable irrigation strategy when water restrictions are imposed during periodic droughts, and if more grapes can be produced with the same volume of irrigation water when…

Winery wastewater irrigation (Part 8): Vulnerability of selected soils in areas with different rainfall
The objective of the study was to investigate the effect of simulated winter rainfall on leaching of basic cations in soils irrigated with diluted winery wastewater.
Winery wastewater irrigation (Part 7): Effect on soil enzyme activities
The objective of this study was to determine the effects of irrigation with diluted winery wastewater on the activities of urease, beta-glucosidase and phosphatase of four soils varying in parent material and clay content.
