Vinpro Technical Harvest Report 2026

of chill units commenced later than normal but exceeded that of the previous winter by June and July 2025. This factor appears to have been one of the most important favourable drivers of the season. The winter, however, ended early, with drier and warmer conditions recorded in August. Warm, dry spring conditions resulted in bud burst occurring approximately seven to ten days earlier than normal, with notably uniform bud break and minimal frost damage reported. Higher soil temperatures promoted early and healthy vegetative growth. These conditions were largely favourable for flowering, fertilisation and fruit set, although some late cultivars, such as Cabernet Sauvignon and Colombar, exhibited weaker set. Overall, improved bunch numbers per vine were recorded, particularly in early cultivars such as Chardonnay, Pinotage and, to a lesser extent,

Chenin Blanc and Sauvignon Blanc, indicating the positive impact of adequate winter chill and optimal spring conditions. The early, dry summer trend shifted in February, with widespread rainfall and moderate to cool maximum temperatures recorded. Heavy showers provided relief, particularly in the eastern parts of the wine-producing regions such as the Klein Karoo, Robertson and Cape South Coast, with an uneven and locally intense distribution. Additionally, cool and humid conditions were recorded during the second half of the season in the Northern Cape, Olifants River and Breedekloof/ Worcester regions. Associated sanitary challenges tempered crop expectations in some areas; however, in most cases, damage was limited to cultivars which were at or near their harvest window at the time.
