Latest research findings: Genetic influences in old Pinotage vines

Old Pinotage vines’ berries ripen later compared to younger vines. So, what does this mean? Research to investigate possible genetic influences to improved wine quality in old Pinotage vines has been conducted by Professor Johan Burger at Stellenbosch University. His team compared both gene expression levels and total microbiomes in old (53 years) and young…

In the vineyard – practical advice for April

Overview of the past harvest Where available, make use of NDVI’s to spot the differences in the vineyards. See if this is due to irrigation leakage, soil (sampling), disease (including Leafroll virus) or broken trellis systems. To help the vines build up enough reserves for the next season, apply a balanced fertilizer through the irrigation…

The soil form is Klapmuts of the Malmesbury Shale family, with a moderate water permeability.
