Fruit Quality

Preserving Your Vineyard Assets During Market Downturns. Periods of oversupply and reduced demand can place significant financial pressure on vineyard businesses. When grape prices fall below the cost of production, continuing to manage a vineyard for maximum yield may no longer be economically viable. As a result, an increasing number of growers are considering an alternative strategy known as vineyard mothballing. Rather than removing vines or abandoning a block altogether,

Fertiliser is one of the largest annual operating expenses in many vineyards, yet it is often applied based on historical practice rather than actual vine requirements. In an era of increasing input costs and growing pressure to improve environmental stewardship, soil nutrient analysis has become an essential management tool for vineyard profitability. Many vineyards continue to apply fertiliser at rates that were established years ago. While these programs may have been appr

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

Botrytis bunch rot, caused by Botrytis cinerea, continues to be one of the most economically significant diseases in wine production. Even in regions that are not consistently humid, short periods of rainfall combined with dense canopies and prolonged leaf wetness can create ideal infection windows. The consequences are well known: yield loss, reduced sugar accumulation, compromised flavour development, and oxidative instability in the winery. As sustainability expectations r

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

Deficit irrigation is a precision water management strategy that imposes controlled water stress on grapevines during defined phenological stages to optimize berry composition and ultimately wine quality.
