In many vineyards, pruning is scheduled around labour and logistics rather than vine physiology. However, the period between harvest and natural leaf fall is critical for carbohydrate accumulation, nutrient retranslocation, and dormancy progression. Pruning before full senescence can reduce reserve recovery and weaken vine performance the following season. Post-harvest canopies remain physiologically active long after fruit removal. During this phase, the vine reallocates car

Harvest timing is the most consequential call made in the vineyard. It determines not just yield, but the structural integrity, style, and ageing trajectory of the wine. While sensory cues such as flavour, tannin evolution, and berry condition are essential, three analytical parameters remain central to decision-making: Baume, titratable acidity (TA), and pH. These are not isolated metrics; they function as a system, and it is their alignment that defines true ripeness. Baume

Post-harvest is not a shutdown phase — it is a reserve accumulation phase. Once fruit is removed, the vine reallocates photosynthate and nutrients into trunks, cordons, and roots. These reserves determine spring vigour, bud fertility, early shoot growth, and resilience under stress.

Hot and dry weather events have become increasingly common across Australian wine regions, prompting questions from grapegrowers about the impacts on vine performance and fruit quality and what management strategies might help mitigate negative effects. Sunburn and Berry Damage All grapevine varieties are susceptible to sunburn, though the degree of susceptibility varies with variety and canopy condition. Exposure to high temperatures post-veraison is particularly damaging be
