New workshop launching in November

This month the AWRI is launching a new ‘Improving quality and reducing costs’ roadshow workshop. This workshop provides information to help grapegrowers and winemakers operate more efficiently and profitably when facing financial or natural resource constraints. It will focus on techniques that improve processes and reduce costs, while maintaining or improving grape and wine quality. After launching in Clare and McLaren Vale in November 2016, the workshop will roll out across Australia following vintage 2017.

The workshop is divided into two sessions: one focusing on viticulture and one on winemaking.

The viticulture session begins with a regional overview of electricity, fuel, water, agrochemical spray and other resources used in the region for the current year, sourced from Entwine and other data. This is followed by topics including stretching water further, optimising vineyard yield without affecting quality and the latest vineyard tools to better manage vineyard variation.

The winemaking session reviews key issues faced by the region over the last year based on queries received by the AWRI helpdesk, the past season’s weather and its impacts on current wine composition. This is followed by two interactive presentations– one focused on wine quality analysis and one on winemaking processes.

The Clare Valley workshop is on Tuesday 22 November at the Rising Sun Hotel in Auburn. Visit the event page to view the program and register to attend.

The McLaren Vale workshop is on Tuesday 29 November at the McLaren Vale & Fleurieu Visitor Information Centre. Visit the event page to view the program and register to attend.

For more information, please contact the AWRI events team on events@awri.com.au or 08 8313 6600.

Online Ferment Simulator coming soon

The Ferment Simulator is a repository for all ferment-related data, including baume and temperature readings, juice analysis, actions like pump-overs and additions, and any other analysis performed on the tank. The data collected feeds the algorithms which predict ferment endpoints and identify stuck or sluggish ferments to assist with early intervention.

Powerful What-If and What-Now modes allow modelling of corrective actions before going out to the tank. A digital archive of ferment data also allows users to search back through their ferment history, view old ferments and compare performance.

The Ferment Simulator will be available soon as a free module on the WineCloud. For more information and to be alerted when the app is released, visit the Ferment Simulator webpage.

Survey update

The AWRI would like to thank all of the respondents who took the time to complete the Vineyard and Winery Practices Survey. The survey closed at the end of September, having received around 670 responses. Congratulations are extended to Sheena High of Native Point Wines in Tasmania who won the lucky draw prize of a trip to the Vinitech-Sifel vineyard and winery equipment exhibition in Bordeaux at the end of November. The AWRI would also like to thank Sandra Trew of Promosalons and Vinitech-Sifel for sponsoring this prize. Next steps for the survey project involve aggregation of the data and consultation with industry personnel to add context to the information gathered. A report will be distributed next year.

Functional and luxury foods report and luxury workshops

In 2015, Primary Industries and Regions SA commissioned a study of functional and luxury foods. The goal of this study was to provide the SA State Government and the SA food industry with a roadmap of where food and beverage value chains could switch to higher value-added products and services, sought after in both key Asian export markets and domestically. The key findings of the research project (across a wide range of food and beverages) were captured in a summary report. The SA Government approached the AWRI to collate the findings from the project that are most relevant to the wine industry. These are now available in a report on the AWRI website.
The AWRI is also presenting two workshops on luxury business strategy and design thinking in mid-November. Visit the AWRI events calendar to register or contact Gregoire Patacq on 08 8313 6600 or gregoire.patacq@awri.com.au.

AWRI staff achievements

AWRI Research Scientist Dr Dimitra Capone has been announced as one of three finalists in the ‘Researcher of the Year’ category of the Australian Women in Wine Awards. This is the first year there has been a researcher category, and the AWRI community is delighted that one of our own researchers is in contention. Dimi’s research in recent years has focused on understanding the origin of eucalyptus characters in Australian red wines and investigating compounds responsible for tropical aromas and flavours in wine. The winners of the Australian Women in Wine Awards will be announced on 15 November.

In late September, AWRI Managing Director Dr Dan Johnson was awarded a grant from the SA Industry Leaders Fund (ILF) to participate in the Advanced Management Leadership Program at the Said Business School, University of Oxford, UK. The Industry Leaders Fund is a specialised networking group made up of grant recipients who have operated successful South Australian businesses and achieved excellent results in the ILF leadership test which is based on the same principles as the test applied to Rhodes Scholars. ILF scholars have studied at, or have committed to study at, one of the world’s leading business schools.
