Grapes were sourced from a selection of low-yielding (6 – 7 t/ha) vineyard blocks located on DB Rust’s farm Constantia. The soils are deep red Oakleaf and Hutton ensuring excellent water-retention and adding structure and fullness to the wines. The vines have been planted in such a way to benefit optimally from the cool Benguela current sea breezes. These breezes cause summer temperatures to range between 20 – 30°C.
Harvesting occurred at optimal ripeness when the grapes were between 22 – 23° Balling. Picking was done in the early morning hours to ensure the grapes arrived cool at the cellar. Dry ice and sulphur were added prior to transport to protect the grapes from oxidation. Skin contact was given for three hours and thereafter the free-run juice was separated from the pressed juice. Reductive winemaking practices were followed to retain as much flavour and complexity in the wine as possible. 60% of the Sauvignon blanc was fermented in stainless steel tanks, the juice was inoculated and fermentation temperature was kept at around 12°C for three weeks. 40% of the Sauvignon blanc underwent barrel fermentation in 100% first fill 500L untoasted Sylvain French oak barrels. The barrels were rolled once weekly after fermentation followed by once a month for four months. Barrel maturation lasted for four months before blending and bottling took place. This allowed for the retention of the fruit component.
The 2017 harvest in the Swartland obtained slightly larger crops following sharp declines in 2016 and larger than expected because of the dry season. Cooler nights during the growing season and more significant heatwaves during harvest time buffered the effect of the drought. The warm and dry weather resulted in small and healthy berries with good intensity, sufficient sugar levels and low.
