Launching Affinity Labs – a new identity for our commercial activities
27 June 2022 >27 June 2022
Today is an exciting day for the AWRI, as we launch a new identity for our commercial activities – Affinity Labs.
The AWRI has offered commercial services to grape and wine producers for more than 30 years. Over that time, our commercial arm has evolved with the times, tailoring services to meet industry demand and adopting new technologies and capabilities. Now the business is taking the next evolutionary step, expanding our offering and focusing on improved customer service under the Affinity Labs banner. By differentiating Affinity Labs from our research activities, we will apply our expertise to support a wider range of food and beverage producers. This will improve economies of scale, expand our knowledge and ensure the ongoing sustainability of our world-class grape and wine research, development and extension activities.
Affinity Labs customers can expect highly respected technical capabilities with a renewed focus on streamlined processes and an improved customer experience. Customers will access services via a new standalone website (affinitylabs.com.au), which will soon include simplified sample submission and reporting.
The AWRI’s services to grape and wine industry that are supported by Wine Australia, including the helpdesk, roadshows and library, will of course continue to be free to access for all Australian grape and wine levy payers.
At the AWRI we will remain focused on the grape and wine industry, delivering cutting-edge research to tackle the challenges and opportunities we currently face and providing valued services to grapegrowers and winemakers.
Affinity Labs is being launched today at the WineTech trade exhibition at the Adelaide Convention Centre. If you’re attending the 18th AWITC or WineTech, please drop by stand 1113 to chat to the team any time from 27 to 29 June 2022.
If you’d like to know more about Affinity Labs, don’t hesitate to contact AWRI Managing Director Mark Krstic (mark.krstic.com.au) or Affinity Labs General Manager, Dr Eric Wilkes (eric.wilkes@affinitylabs.com.au).
AWRI Board seeks new Chair under revised composition and recruitment processes
21 June 2022 >21 June 2022
The AWRI Board is today launching a search for two non-executive Directors, one of whom who would act as Chair from January 2023.
The position of Chair will become vacant in December 2022, when highly respected and long-standing Chair, Louisa Rose, reaches the end of her term on the Board under the rules of the AWRI Board Charter.
A nominations committee has been formed to recruit the two new Directors. More information about the positions and how to apply is available from the AWRI Careers webpage.
This recruitment follows an industry consultation period in October 2021 in which changes to the AWRI Board’s composition and appointment processes were proposed to ensure the AWRI remains up to date with best-practice corporate governance and continues to meet the needs of the Australian grape and wine industry. The proposed changes were approved by the AWRI Board in February 2022. These changes include:
- The introduction from January 2023 of a position elected by Grape Research Levy payers
- Reducing the number of positions elected by levy payers from six to four, including one position nominated and elected by each of the small, medium and large category Wine Grapes Levy payers and one position nominated and elected by Grape Research Levy payers.
- Increasing the maximum number of Appointed Director positions from four to six, to ensure an appropriate balance of skills and diversity (including geography).
- Introducing a nominations committee, made up of a mix of independent members and current Directors, to assist in the selection and reappointment of Appointed Directors.
- Incorporating an open recruitment process for the appointment of Appointed Directors, seeking expressions of interest to address identified gaps in the Board’s skills and diversity.
- Introducing a gender diversity quota for non-executive Director positions, specifying a minimum of at least four Directors of either gender.
AWRI stakeholders are encouraged to circulate this opportunity among their networks, to ensure the widest possible pool of qualified candidates for these important roles.
For more information about the changes to the AWRI Board’s composition and appointment processes, contact AWRI Company Secretary, Shiralee Dodd on (08) 8313 6600 or Shiralee.Dodd@awri.com.au.

As vintage 2022 wraps up around Australia, thoughts will be turning to packaging for many wine producers. The AWRI helpdesk often sees the results when packaging goes wrong, whether it be insufficient heat or cold stabilisation, ineffective filtration, incorrect bottle pressures or simply not enough SO2. In fact, packaging and instability-related queries accounted for around 15% of total queries received last year and resulted in many complex investigations. To help producers avoid some of these common problems, the team developed a comprehensive set of resources on packaging. These cover steps from pre-packaging preparation right through to transport and storage. If you need help or have any packaging-related questions, contact the helpdesk on helpdesk@awri.com.au or 08 8313 6600. |
New fluorescence method for detecting haze-forming proteinshe methods currently used for testing heat stability of white wine can be time-consuming, expensive and may not always accurately predict the amount of bentonite required to achieve protein stability. This could lead to over-fining, which might strip out phenolics and aroma compounds, or under-fining, which could increase the risk of protein instability. As an alternative, an efficient and rapid fluorescence-based method to detect haze-forming proteins in white wines has been developed at the AWRI, with the work recently published in the journal Food Chemistry. The method uses a fluorescent compound that binds haze-forming proteins selectively. To validate it, a range of wines were analysed with results compared to an established HPLC method. A linear relationship was observed between the two methods over a range of relevant haze protein concentrations and the new method showed a low detection limit of 2 mg/L. The new technology can be deployed rapidly, without sample preparation, presenting an opportunity for routine testing. The full paper detailing this work is available from the AWRI library: Mierczynska-Vasilev, A., Vasilev, A., Reilly, T., Bindon, K., Vasilev, K. 2022. Fluorescence sensing technology for the rapid detection of haze-forming proteins in white wine. Food Chem. 374: 131770.

New partnership with international society |
|
 |
The AWRI recently joined The International Viticulture & Enology Society (IVES) as an academic member. IVES is an international academic association dedicated to viticulture and oenology. Founded in 2017 by a group of leading universities and research institutes, it aims to make the results of scientific research in this field freely available for researchers and professionals. IVES publishes OENO One, a vine and wine online open access peer-reviewed journal, IVES Technical Reviews – Vine and Wine, a tool to transfer current research to end users, and IVES Conference Series – Viticulture and Enology to collate proceedings from international conferences in viticulture and oenology (launched in 2021). |
Practices survey coming later this yearThe AWRI will be commencing the second edition of its comprehensive grape and wine practices survey in September. This follows the first survey conducted in 2016, which produced a detailed snapshot of vineyard and winery practices and equipment in use at that time. The goal of the survey, which will be repeated every six years, is to provide independent data tracking the evolution of vineyard and winery practices and technology adoption. If there are topics, practices or equipment that were not covered in the original survey that you think should be included in this second edition, we are interested to hear from you. Please email simon.nordestgaard@awri.com.au to suggest new additions to the survey. |

Sustainable Winegrowing Australia certification for WIC Winemaking Services |
|
 |
WIC Winemaking Services, the specialist contract winemaking service operated by the AWRI and the University of Adelaide, has just become a certified member of Sustainable Winegrowing Australia. This certification is testament to work conducted by Winemaker, John Gledhill and Assistant Winemaker, Russell Desmond, to collate all the required sustainability data, undergo training to prepare for certification, be audited and then perform any actions resulting from the audit. The team is proud to be able to demonstrate its sustainability credentials to all its clients. For more information on the services available from WIC Winemaking, contact john.gledhill@awri.com.au.
For other wineries or vineyards interested in certification, attendance at a certification training workshop is the first step. To receive notifications of all upcoming AWRI certification workshops, complete this EOI form. |
Major grant for no- and low-alcohol productionA $4.8 million grant was recently announced by the South Australian Government for the development of a world-leading no- and low-alcohol (NOLO) wine production capability. This funding will enable industry to undertake pilot-scale production of new NOLO products and better understand the market opportunities in this growing consumer segment. The program funded by the grant will be delivered by the AWRI, the University of Adelaide, Wine Australia and Australian Grape & Wine and is structured as four pillars: Pillar 1 – Establishment of a pilot/trial-scale production facility The AWRI will be directly involved in Pillar 1 (led by WIC Winemaking Services) and Pillar 2 (led by Dr Wes Pearson, Dr Simon Nordestgaard and Dr Josh Hixson). For more information, contact enquiries@awri.com.au. |

Smoke background data published |
|
 |
When grapes are analysed to assess the risk of smoke exposure, the marker compounds used are a selection of volatile phenols and their glycosides. However, these compounds are also present naturally at trace levels in non-smoke-exposed grapes, which can complicate the interpretation of smoke analysis results. To address this, the AWRI collected data on the trace levels of smoke marker compounds in non-smoke exposed grapes of 12 varieties across Australia over four vintages. The grapes were fermented to wine and the concentrations of marker compounds in the wines were also added to the database. Analytical results for grapes or wine can be compared to the background levels database to determine the likelihood of smoke exposure. This work has recently been published as an open access article in the Australian Journal of Grape and Wine Research. The AWRI is working on expanding the background levels database to 16 varieties and data for additional varieties will be collected this vintage. |
Vintage trials underwayAs vintage 2022 kicks off around Australia, AWRI researchers are also busy setting up this year’s crop of vintage trials, which form an important part of many research projects. Some of the goals of this year’s trials include:
The AWRI thanks all the industry collaborators involved in these and other trials and looks forward to sharing the results. For more information on any of these trials, please contact enquiries@awri.com.au. |

Resources on scale and sooty mould |
|
 |
A number of regions across Australia have recently reported issues with scale insects on vines and associated sooty mould on grape bunches. Scale insects are common in Australian vineyards but typically do not cause enough damage to warrant action to control them. In some circumstances, however, the population can reach a threshold where intervention is required to avoid fruit being downgraded or rejected. The AWRI’s page on scale insects and sooty mould provides a range of useful resources, including fact sheets, articles and a webinar detailing a red wine trial conducted in 2017 with sooty-mould-affected grapes. For more information or assistance, contact the AWRI helpdesk on helpdesk@awri.com.au or 08 83136600. |
Latest information on sensors and automationAWRI Senior Engineer, Simon Nordestgaard, has been keeping his finger on the pulse of developments in tank instrumentation and has conducted trials of some of the latest sensors that can help to automate manual processes. He published updates on this work in two recent articles in the Australian & New Zealand Grapegrower and Winemaker, with the first focusing on automated ways to measure ferment density and liquid volume, and the second covering new options for measuring H2S in ferments. This vintage, Simon will be extending this work, focusing on density measurements in red ferments and yeas cultures. |
