Nominations sought for grapegrower representative on AWRI Board

Following changes to the AWRI Constitution earlier this year, the AWRI Board now includes for the first time one person who is nominated/elected by grape research levy payers. The AWRI is therefore calling for nominations from grape research levy payers for this position, as well as for a person nominated under the large (>50,000 tonne) wine grape levy payer category.

Nominations are to be received by post to The Returning Officer, The Australian Wine Research Institute Ltd, PO Box 197, Glen Osmond SA 5064 or by email to returningofficer@awri.com.au NO LATER THAN 5 PM FRIDAY 21 October 2022. If more than one nomination is received in each category, an election in that category will be conducted during November 2022. Details and nomination forms are available from the Election and appointment of Directors page on the AWRI website.

AWRI Board announces two appointments, including next Chair

Prof. Kiaran Kirk with current Chair Louisa Rose

The Hon. Sarah Courtney

The AWRI Board recently announced the appointment of two Directors, Prof. Kiaran Kirk and The Hon. Sarah Courtney. These two Directors were appointed through a new process put in place following updates to the AWRI Constitution in 2022. A nominations committee, chaired by former Director Dr John Harvey, conducted a rigorous and independent recruitment process, which recommended Prof. Kirk and Ms Courtney to the Board and that recommendation was accepted at the most recent Board meeting. The Board also resolved that Kiaran would take on the role of Chair from 1 January 2023, following the conclusion of current Chair Louisa Rose’s term on 31 December 2022. Kiaran and Louisa will work closely together between now and the end of the year to ensure a smooth transition.

More than 1,000 members for Sustainable Winegrowing Australia

After a busy membership renewal period the Sustainable Winegrowing Australia team has crunched the numbers and is delighted to report some significant membership milestones:

  • 48% growth in overall program membership in FY22
  • certified members more than doubled in FY22
  • 1,062 members as of 15 September, up almost 15% from 30 June 2022
  • almost 700 people completed certification training and are preparing for certification in FY23

This momentum reflects the strong and growing commitment to sustainability across the Australian grape and wine community. The team is currently reviewing all of the data submitted during the renewal period, with benchmarking reports to be released to members in October. More information about the program is available from sustainablewinegrowing.com.au.

Practices Survey – make sure your data is counted

The AWRI Vineyard and Winery Practices Survey tracks the practices used in vineyards and wineries across Australia, helping to inform future R&D and extension activities. The survey is repeated at six-yearly intervals to discover how practices and technologies are changing. Your help is needed to ensure the data is representative of Australian grape and wine production. Please visit https://bit.ly/2022-practices-survey now to take part. Thank you for taking the time to contribute.

New fast and accurate method for detecting Brett in wine

Affinity Labs is offering a new flow cytometry-based method known as BrettCount for detecting viable Brettanomyces cells in wine. This method uses a mixture of fluorescent gene probes targeting different regions of the 16s ribosomal RNA of Brettanomyces cells to rapidly detect and quantify them in wine. The method has high specificity and does not cross react with other species that may be present in wine. The limit of detection is 100 cells/mL. Only viable cells are detected, although some cells that are not culturable under laboratory conditions can also be detected. BrettCount is rapid, with results obtained within one day. A recent comparative study showed that BrettCount correlates better with the ‘gold standard’ selective plating method than other rapid methods. For more information or to submit samples for BrettCount analysis, contact customerservice@affinitylabs.com.au.

Register to be part of NOLO innovation

Wine Australia and the AWRI are seeking expressions of interest from growers, winemakers and wine supply-chain partners for a new no or low alcohol (NOLO) wine research innovation program. Complete your submission at wineaustralia.com/nolo-wine-eoi before Friday 14 October 2022 to help shape the program by outlining your current and projected aims, obstacles and opportunities for NOLO wines.

Affinity Labs events – coming soon!

The Affinity Labs team will be on the road soon, visiting regions to meet with customers, discuss the latest services and hear how Affinity Labs can best support growers and winemakers across different areas. Keep an eye on the Affinity Labs event page to find out when the team is visiting your region.
