Managing the impact of vintage advancement and compression
Vintage compression due to climate change is well-documented. The period between the harvest of early maturing varieties, such as Chardonnay, and that of late ripening varieties, such as Cabernet Sauvignon, is becoming shorter. This places significant stress on processing logistics and capacity at the winery as well as delaying fruit harvest, which results in fruit with high sugar, leading to elevated alcohol concentrations in wine.
This project aims to better understand the dynamics of sugar accumulation, fruit composition and ripening parameters during grape maturation under climate change conditions. And, to trial water addition (as a remedial strategy to deal with high Baume musts) on wine quality and style.
