The 2019 growing season was extremely dry and warm. In the 12 months to March, the region had only 61% of the long-term average rainfall. Spring temperatures were slightly below-average driven by lower minimum temperatures (-2.5°C) including two below 0°C events during September, which resulted in frost events on 4th September and 29th September. Summer was very warm, with December and January well above-average driven by a combination of both higher maximum and minimum temperatures. The Kalimna vineyard experienced 31 days of temperatures exceeding 35°C. While March was also dry, crucially it was not too hot allowing for an orderly harvest. Low yields delivered Barossa Valley shiraz with dark colours, intense depth of flavour and ripe firm tannin structure.
