Abstract
The root of our problem is that, by trying to optimise the yield-quality seesaw and understand vine balance, we often forget to go below ground. Potted vine systems are a model system that presents the opportunity to explore these challenges. Since this trial has confirmed that we can successfully increase the size of competing sinks (roots), which leads to changes in our vine balance (overall increased vegetative growth, but no increase in yield) in this model system, we can now extend the investigation to explore potential effects on the grape composition in response to changing the yield­-quality seesaw. This will allow us to better understand the limitations of tilting the yield-quality seesaw at different vineyard conditions in practice while maintaining a sustainable vine balance.
