Happy New (Events) Year!

awac_600px The AWRI would like to wish eNews readers a happy new year and all the best for vintage 2017! The events team has been busy planning the 2017 calendar, and is scheduling a wide range of events for grape and wine producers. The year is kicking off with a tasting workshop on Pinot Noir winemaking, being held across Australia in late January and early February. AWRI roadshow seminars also come to Tasmania in February. Then, following a break for vintage, the AWRI webinar program continues with presentations on closures and the effects of partial dealcoholisation. In late May/early June there will be two Advanced Wine Assessment Courses and a Wine Judging Course to develop tasters’ wine judging skills. And from May until the end of the year there will be a focus on the new roadshow workshop ‘Improving quality and reducing costs’ and AWRI roadshow seminars. The online AWRI events calendar is being continually updated – so please check back regularly to keep in touch with events in your region or contact the events team on events@awri.com.au or 08 8313 6600 if you have any queries.

Ferment Simulator now available

The AWRI has just launched an online version of its Ferment Simulator. This free app, hosted on the AWRI’s WineCloud platform, brings the power of the algorithms from the original Excel-based Ferment Simulator into a new online format designed for ease of use on both desktops and mobile devices.

Ready to go for vintage 2017, the new Ferment Simulator can be used to store all ferment-related data. This includes 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 aid 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 is available free for Australian wine producers – for more information and to register for an account, visit the Ferment Simulator webpage.

Understanding regional spray practices

sprayer-enews-res1 The AWRI has recently commenced a project looking at spray practices across Australia’s grapegrowing regions. By accessing anonymous spray diary information at the end of each season, it will be possible to understand the products and practices used in different regions, establish benchmarks for best practice and highlight opportunities for improvements.

Findings from the project will be disseminated through the new AWRI workshop ‘Improving quality and reducing costs’, with a presentation of spray data from the relevant region included in each workshop.

Prior to each workshop, local input will be sought to provide context to the spray data in terms of the varieties planted and disease pressure experienced in that region. Case studies for growers will also be developed as the project progresses. For more information, contact the AWRI helpdesk on helpdesk@awri.com.au.

Two yeast reviews published

Late in 2016 two review articles on wine yeast were published by AWRI scientists. The first, titled ‘Yeasts found in vineyards and wineries’ and published in the journal Yeast, summarises the wide range of yeasts isolated from vineyards, wineries and ferments by scientists across the world. The second, titled ‘The impact of non-Saccharomyces yeasts in the production of alcoholic beverages’ explores research on the effects of non-Saccharomyces yeasts on the composition and sensory characteristics of wine and other beverages. It also looks at future opportunities involving interactions between yeast species and ways to express regional characters in alcoholic beverages. To request a copy of either of these two review articles, please contact the AWRI Information Services team on infoservices@awri.com.au.

Grapes needed for smoke taint background study

grape-bunch-360px The AWRI is seeking 1-2 kg samples of grapes that have not been exposed to smoke as part of its continuing smoke taint baseline study. This study is working to improve the interpretation of smoke taint analysis of grapes. If you are able to contribute grapes, please contact helpdesk@awri.com.au. The samples will need to be picked about two weeks before harvest, frozen immediately and then transported to the AWRI post-vintage. The grape varieties being sought for 2017 are: Mataro, Sangiovese, Grenache, Merlot, Pinot Noir, Riesling, Semillon and Pinot Gris.

The smoke taint baseline study is collecting data on the natural ‘background levels’ of smoke taint compounds that are present in grapes that have not been exposed to smoke. Improved smoke taint analysis interpretations will enable winemakers to make better decisions about whether to accept/reject grapes that might have been exposed to smoke.

If you can collect samples, the AWRI will send you sample bags, cable ties and labels, as well as information about shipment and possible quarantine requirements. All sample transport costs will be covered. To volunteer to provide samples or for any further information, please contact helpdesk@awri.com.au.

Regional sample drop-off locations sought

AWRI Commercial Services is seeking to establish drop-off locations in regions across Australia. Grape and wine producers will be able to leave samples at these locations to be couriered to the AWRI laboratories. The goal of this service is not to compete with local providers of analytical services, but instead to provide easier access to services not available locally, such as smoke taint analysis and other advanced analytical techniques. The Hunter Valley is likely to be the first region to host one of these drop-off locations.

It is expected that sample login and payment would be carried out by the customer through the AWRI’s web-based login service and would not require any input from the drop-off location provider. For more information or to express interest, please contact Dr Eric Wilkes (eric.wilkes@awri.com.au) or 08 8313 6600.

Introducing Showrunner

The AWRI’s Advanced Wine Assessment Course last year introduced electronic scoring – a move that was positively received by participants and allowed the course to run more smoothly and efficiently. The in-house scoring software has now been expanded into a new system, known as Showrunner, that can manage all aspects of running a wine show – including online entries, electronic scoring and instant results. Showrunner was successfully used at the recent Hunter Valley and Orange wine shows and is available for other shows to use in 2017.

Key features of the system include: the ability for exhibitors to enter wines across multiple shows, instant availability of results, capturing of both scores and comments from judges and the ability to calculate trophy winners. Showrunner is constantly being updated and improved based on user feedback, to ensure it will suit a wide range of wine shows across Australia. To find out more about Showrunner, contact Con Simos or Francesca Blefari on 08 8 313 6600 or events@awri.com.au.

The day of bottling has finally arrived

>

It was an early start in the Barossa, but Ray Todd was already there, and everything was ready to go.

In Ray’s capable hands
1
Thanks to Corey Ryan at Sons of Eden, for the loan of a perfectly sized tank at the weekend.
2
And the copper solution I’d taken up a few days earlier, had been added (0.1 ppm as Cu).
3
The DO was perfect, but we brought the CO2 up to 0.6 g/L
4

Ray in his lab
5
We had a final sulfur analysis done at the winery next door. The colour of the wine was fabulous when the SO2 had been bubbled out. The brief was to make a wine which looked good after two years, and would live for twenty. That’s what we had – we just needed to get it into bottle safely.
6
And it tasted great.
7

Everything was set to go.

9
And bottling begins!

11

The first carton.
12
There was plenty of attention to detail from both Linda Todd and Ray

A job well done. Thanks to you all at Barossa Bottling Services!

Ready for bottling

23 November 2016 >

It’s now the week before bottling, and the wine has been cold for three weeks.

We’d done some trial blends to see if we could tweak the wine in any way. The wine on its own was very solid, and very Barossan. The only thing we tried which gave it a bit more structure and length without changing its intrinsic character, was a 1.75% addition of a 2016 Barossa Cabernet.

The combination of cold temperatures and the Cabernet addition, resulted in a surprising deposit in the tank – but that’s why we got it cold in the first place.
9
And the deposit contained a lot of tartrate.
10
The lees were bulked-up and left to settle at zero degrees for a few days, and racked again.
11
And this was all we discarded at the end.
12
The wine ended up well within the spec for turbidity, all achieved by careful racking, with no filtration.

The three tanks were dry-iced, and the finished wine was ready to go back to the Barossa, for bottling.
13

Tanks ready to go
14
With our trusted carrier who did such a great job for us when the heat was on (literally!) during vintage 2015.
15
16

The wine had arrived at Barossa Bottling Services by late afternoon.
17
As had our bottles.
18
And we held an early-evening meeting with the irrepressible Ray Todd, to go over the bottling specs.

The irrepressible Ray Todd.

By the way, this is a very rare photo of Ray – he’s not on his phone!

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

gauge The AWRI will launch a new Ferment Simulator module for the WineCloud next month. This free app brings the power of the algorithms from the original Excel-based Ferment Simulator into a new online platform designed for ease of use on both desktops and mobile devices.

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.

Grape samples needed for smoke taint background study

grape-bunch-360px The AWRI helpdesk team is continuing its smoke taint baseline study during 2017 to improve the interpretation of smoke taint analysis of grapes. This project is collecting data on the natural ‘background levels’ of smoke taint compounds that are present in grapes that have not been exposed to smoke. Improved smoke taint analysis interpretations will enable winemakers to make better decisions when faced with grapes that might have been exposed to smoke. The AWRI is seeking 1-2 kg samples of grapes that have not been exposed to smoke. The samples will need to be frozen once picked and then transported to the AWRI post-vintage. If you are able to collect samples, the AWRI will send you sample bags, cable ties and labels, as well as information about shipment and possible quarantine requirements. All sample transport costs will be covered. To express your interest in being involved or for further information, please contact helpdesk@awri.com.au.

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.

Entwine logo now available for members

Entwine The Entwine logo is now available for members to use. All Entwine members are encouraged to display the Entwine logo in their marketing materials to promote their participation in the Australian wine industry’s sustainability program. Certified members can also use the logo on wine and its packaging provided that at least 85% of the grapes in the wine were grown in a Certified member vineyard and the wine was made in a Certified member winery. The Entwine logo files and rules for its use are now available for download from http://www.entwineaustralia.com.au/.

New online tool to identify best rootstocks

Organic vineyard in McLaren Vale, Australia

Organic vineyard in McLaren Vale, Australia

Wine Australia has released a free online tool that will help wine-grape growers determine the rootstocks that will best suit their vineyard – the Grapevine Rootstock Selector. By answering a series of questions about their vineyard, growers can use the Grapevine Rootstock Selector to identify a small number of appropriate rootstocks for their vineyard. The Grapevine Rootstock Selector brings together knowledge from Australian and international research about the specific characteristics of different rootstocks and is based on a tool first developed in 2002 by Yalumba Nursery. Visit http://www.grapevinerootstock.com to try out the new tool.

WINEHEALTH 2017 dates announced
