Managing grape maturity variability

Unsynchronised berry ripening results in significant proportions of under-ripe and overripe fruit remaining at the time of harvest, which is known to be detrimental to Australian red wine quality. In this podcast, we will discuss management systems that have potential to modulate grape maturity variability at the time of harvest, as well as the effects on red wine flavour and aroma profiles. On the episode, we will have viticulturist, Pete Balnaves from Balnaves of Coonawarra, and PhD student, Claire Armstrong from The University of Adelaide, and Dr David Jeffery, Associate Professor in Wine Science, The University of Adelaide, to give the wine industry’s and researcher’s experience with managing grape maturity variability.

Yield assessment

This podcasts look at yield assessment a topics close to the heart of many growers and winemakers because getting it right delivers great benefits – and the costs of getting them wrong can be huge. This information would allow growers to make accurate yield assessments based on five-year historical averages, and also to be a step ahead when non-human-based yield assessment systems are improved as they are expected to draw on accurate historical information.Louisa Rose, Chief Winemaker at Yalumba Family Winemakers and Dr Mark Whitty, Senior Lecturer in Mechatronics at the University of New South Wales.

Optimising irrigation

The podcasts looks at irrigation efficiency and explains the importance of system maintenance and how using data from weather stations, soil moisture probes or plant sensors can reduce water use by 40–75 per cent without affecting yield or quality.

Water management resources

The AWRI has a wide range of water management resources – including fact sheets, articles and webinars – to help growers to use their water most effectively, achieving yield and quality targets.

What will my region’s climate look like in the future?

A three-year project with the University of Tasmania brought together an extensive, multi-disciplinary research team to consider the impact of seasonal climate variability and longer-term climate trends on the wine sector in Australia.It has generated the finest available climate projections for Australia’s wine regions and provided detailed information about how the climate may change in the near, mid and long-term time horizons (out to 2100). This information has been incorporated into the Australia’s Wine Future: A Climate Atlas, a free online resource of climate information for all Australian Geographic Indications (GIs).The atlas helps to answer the question – what will my region’s climate look like in the future? This is essential knowledge for making good management decisions, based on decadal changes, and supporting strategic decisions over the longer term, both within and between regions.Tailored climate indices were calculated for every Australian Geographical Indication and include:

  • temperature – growing season temperature (GST); growing degree days (GDD)
  • rainfall and evaporative demand – annual, monthly and seasonal rainfall; growing season rainfall; number of rainy days during harvest; annual, monthly and seasonal aridity; number of dry spells before harvest
  • heat extremes – extreme heat factor (EHF) during a heatwave; heatwave duration and intensity; number of days per year exceeding temperature thresholds; frequency of days with high human heat stress; and
  • cold extremes – number of days at risk of frost during the growing season; daily minimum temperature; annual chilling degree days; number of days per year temperature falls below temperature thresholds.
