Treasury Wine Estates' (ASX:TWE) shares inched down in recent trading on Wednesday after Wine Australia said in a same-day report that Australia's 2026 winegrape crush fell to 1.3 million tonnes, the smallest since 2000.
The 2026 crush was down 306,334 tonnes, or 19%, from the 2025 national crush and 25% below its 10-year average of 1.7 million tonnes.
The crush equates to around 33 million fewer nine-liter cases of wine.
The 2026 crush reflected both seasonal pressures, including flooding in the inland regions and a broader response to changed consumer demand, said Peter Bailey, manager of market insights at Wine Australia.
