Managing and modelling vintage compression

Anecdotal observations and the analysis of fruit maturation records suggests that, in addition to earlier maturity, the period over which the fruit ripens is getting shorter. This is potentially caused by a convergence in maturity of early and late maturing vineyards of the same variety within a region; the convergence of maturity between different varieties within a region and the convergence in maturity of varieties grown in different regions. This vintage compression places increasing pressure on harvest and processing logistics.

This investment will:

  • investigate the drivers of vintage compression between varieties, and within and between regions,
  • evaluate models to predict variation in harvest date within a region,
  • evaluate management options to spread the maturity for red varieties in commercial regions that use machine pruned systems, and
  • assess the risks associated with delaying maturity in current and future climates.

Volatile compound insights: Flavour attributes of current and future commercial significance to growers and winemakers

Understanding the formation and fate of key volatile compounds is a core capability that requires continuation in our sector, as these compounds provide researchers and producers with quality targets for improvements in vineyard and winemaking practices. Volatiles contribute specific varietal and regional characters and contribute greatly to the overall in-mouth sensory experience. The volatiles of wine can be the mark of its quality for a consumer when drinking or the basis of its rejection and are influenced at every stage of handling or processing. At the core of an innovative sector is the ability to understand and measure key volatiles, while developing practices to influence or control flavours associated with wine quality and style.

Genetic diversity of Australian wine grapevine germplasm

Grapevine planting material represents a major investment and critical production asset for the Australian wine industry, but the genetic diversity that is present in Australia is poorly understood. Furthermore, while grapevine cultivars can be unequivocally typed by ampelography and/or genetic tests, clonal identification solely relies on the tracing of supply records to the point of origin. Such records are not always available or reliable, particularly for older accessions. Whole genome sequencing (WGS) provides the most highly detailed methodology for defining grapevine cultivars and more importantly, clones of those cultivars.
