Towards a circular economy in winemaking – re-utilisation of yeast lees
Researchers explored the feasibility of using processed yeast lees generated during alcoholic fermentation as a nutrient supplement in subsequent fermentations.
Research update: The quest for new Pinotage clones
Given the importance of Pinotage for South Africa, the existence of only a few commercial clones is a limitation. The potential for a more diverse set of clones is desirable and crucial for this cultivar’s continued success and growth.
Vine and wine innovation watch: Electronic noses
Electronic noses, or E-noses, have emerged as game-changing tools in various fields, including biomedicine, environmental science, industrial materials production and the food industry.
The Confronting Climate Change initiative
The CCC initiative is a carbon footprinting program specifically designed to assist fruit and wine organisations in addressing the challenges posed by climate change.
Treated municipal wastewater for irrigation (Part 5): Soil hydraulic conductivity
This study's objective was to assess the long-term effects of irrigation with treated municipal wastewater (TMW) on soil hydraulic conductivity in commercial vineyards in the Coastal region of the Western Cape.
Treated municipal wastewater for irrigation (Part 4): Soil chemical responses
This study’s objective was to assess the effects of long-term irrigation with treated municipal wastewater (TMW) on soil chemical properties in commercial vineyards in the Coastal region of the Western Cape.
What is a ‘microbiome’, and how does it relate to wine?
Have you ever wondered what gives your favourite bottle of wine its distinct character? Part of the answer lies in a world invisible to the naked eye, but crucially helping to shape the taste and quality of wines: the microbiome.
Confronting Climate Change’s Light Workshop
Confronting Climate Change (CCC) offers a range of workshops tailored to different needs and expertise levels. These include Light and Full Workshops, as well as the more advanced Agri-Carbon Crash Course.
Vineyard response to the floods in the Olifants River region during 2023
It is not uncommon for regional producers to see vineyards against the Olifants River under water during the winter months. It is usually a welcome sight and means that the catchment areas of the Olifants and Doring River Schemes received good rain.
Calcium tartrate instability
Calcium-induced instability is a most insidious problem in bottled wines mainly due to the unpredictable and slow formation of crystals, which usually do not come out of solution for some time after bottling and often after commercial release.
Treated municipal wastewater for irrigation (Part 3): Yield and juice characteristics
This study’s objective was to assess long-term irrigation sustainability with treated municipal wastewater (TMW) on grapevine yield and juice characteristics in the latter part of a field trial in commercial vineyards in the Coastal region of the Western Cape, South Africa.
Biosand reactors and anaerobic digestion – a zero-waste model for winery wastewater (Part 2)
A number of studies have been conducted focussed on optimising the operation of biosand reactors for remediating winery effluent.
