Barossa Valley 1983 Vintage Report
For much of the season, 1983 looked destined for greatness in Barossa Valley, until the elements conspired against it in the final weeks.
The cycle began with a harmonious flowering period. Warm days (avg 21°C) allowed for an even fruit set, establishing the potential for a generous crop.
Summer turned up the intensity. With 20 days soaring above 35°C, the vines faced a stress test. Yet, thanks to sufficient water reserves, the canopy remained green, protecting the clusters from sunburn. A key factor was the dramatic diurnal shift (12.1°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.
The finale was fraught with tension. A deluge of 105mm during the harvest period forced an expedited picking schedule to mitigate botrytis risks, rewarding those who sorted ruthlessly.
**Style:** Powerful but variable, with the best wines balancing the heat with careful selection.
