New labelling device assists wine consumers

In conjunction with industry partners, the AWRI has officially launched the PinotG Style Spectrum – a simple labeling device allowing consumers to identify the styles of Pinot Grigio and Pinot Gris wines at a glance, before they purchase or open the bottle.

The ‘Spectrum’ represents cutting-edge science which is believed to be a world-first in being able to ‘fingerprint’ wine style, and then graphically represent that style on a wine label.

The launch has generated a great deal of press attention to date, with articles appearing in the Sydney Morning Herald, the Age, Weekend Age, the Weekend Australian magazine, and the Australian Financial Review, with many web-based articles also appearing in a total of six different countries.

Why PinotG? The Pinot Grigio/Pinot Gris variety has been known in Europe since the Middle Ages, chiefly in the Alsace region of northeastern France and in northern Italy. Traditionally, the style of wines produced in northern Italy and labeled Pinot Grigio have been crisp and zesty, while Alsatian wines, labeled Pinot Gris, have been luscious and rich in texture. However, in Australia, a wide range of wine styles are being produced, which has caused confusion. Some wines are crisp and zesty, others are luscious and rich in texture, and some show every conceivable combination of these characteristics. Consequently the name of the variety used on the label is difficult to relate to the wine style in the bottle.

Our tasting panels, which included many Australian winemakers, agreed that some wines were crisp and zesty, while others were luscious and rich, and others showed combinations of those attributes to varying degrees; in fact a ‘spectrum’ of styles was identified.

We then sought to define objectively what caused those differences in the wines, using spectral analysis, and found differences in things such as the flavor molecules, phenolic compounds, and grape-derived acids in the wines; the various concentrations of which could be thought of as a wine’s ‘fingerprint.’ That spectral ‘fingerprint’ looks at everything in the wine, and is a different concept than looking at and thinking about just a few compositional parameters to explain sensory differences between wines.

The broad range of Pinot Gris and Pinot Grigio wines which were tasted were put through spectral analysis and advanced statistical techniques were used to find correlations between the spectra obtained and the tasters’ ratings of the crispness to lusciousness of each of the wines. That information was used to build a spectral calibration, so that it is now possible to predict accurately the rating of a trained sensory panel for a wines’ crispness to lusciousness using a scan, thereby positioning the wine on the PinotG Style Spectrum.

Wine producers who would like to investigate using the PinotG Style Spectrum on their labels should contact Peter Godden (Peter.Godden@awri.com.au). More information is available at http://www.PinotG.com.au

It’s filtration time prevent those uninvited guests

In September many wineries are filtering their wines ready for bottling. It is essential the correct grade of filtration is used to avoid unwanted guests. Click here to read the article.

A forum to support wineries with technology uptake

Want to improve your winemaking processes to improve your bottom line, but not sure where to start? What processes can be improved and how can you get more from your supplier? Join our forum.

Successful implementation of technology in the winemaking process has been critical for the Australian wine industry. Technology has provided the tools for Australian winemakers not only to craft high quality wines reliably and reproducibly, but also to do it in an economical manner with minimal environmental impact. However, significant opportunities still exist for the Australian wine industry to make the most of advanced manufacturing approaches that are commonplace in highly engineered industry sectors, such as the automotive and mining industries. Australia’s ongoing success in the wine sector will depend on our ability to harness technology as part of our value proposition in the market place.

The AWRI Commercial Services have established a Winery Operations Improvement Forum to explore opportunities for advancement of the wine industry through adoption of new technologies as follows:

  • Understanding barriers to uptake of technology.
  • Identification of common applications between wineries that technology provides a strong value proposition.
  • Review and evaluate the critical process performance criterion and the technologies needed.
  • Establish a forum in which wineries can generate pull technologies from technology suppliers in a cost effective manner.

Our first Winery Operations Improvement Forum meeting was held on 13 July. Eighteen winery operations personnel attended across ten South Australian wineries. One of the key outcomes from the meeting was to establish themes of interest across the wineries for operations technology. The applications of common interest included:

  • Alternative cold stabilisation techniques.
  • Ullage management technologies.
  • Alternative maturation technologies.
  • Refrigeration technologies.

These areas will be established as themes for a series of quarterly forums; the first starting on 29 September focusing on Cold Stabilisation Technologies and Methods. The forum will aim to establish the following:

  • The utility and performance criterion requirements.
  • Available technology options and their relative merits.
  • Opportunities to build bridging technologies or new capabilities to meet operations needs.

Genuine carbon neutral wine recognised for sustainability

Confirming their wine is 100% carbon neutral through an extensive greenhouse gas life-cycle analysis by Karl Forsyth from The Australian Wine Research Institute has paid off for Taylors Wines.

Taylors Wines has been announced as a finalist in the 2010 Australian Packaging Awards* in the category for the Carter Holt Harvey Sustainability Award. This is on the back of winning Best Green Launch at the 2010 Green Awards in London, run by Europe’s leading drinks publication, Drinks Business.

Taylors most recent recognition is for their Eighty Acres 100% Carbon Neutral range of wine products. “The life-cycle assessment considered every step of the supply chain associated with the 80 Acres product, from spray applications in the vineyard, the winemaking process to the consumer’s car journey,” says Forsyth. This detailed life-cycle assessment was then independently reviewed to ensure the work met the requirements of an international standard. The life-cycle assessment work is believed to be the most detailed and robust ever completed on a range of wine products.

The life-cycle assessment also considered the impact of packaging, which led Taylors to move towards a lighter packaging format, substantially reducing their overall emissions.

*The Australian Packaging Awards – organised by the Packaging Council of Australia (PCA) – are a national competition which recognises and rewards packaging design excellence across a diverse range of categories from FMCG to medical to wine and alcoholic beverages to fashion and cosmetics to industrial and agricultural goods.

Key messages from the AWITC inspire delegates

The Australian Wine Industry Technical Conference is over for another three years and most delegates came away inspired. Industry members from Australia and from more than 13 overseas countries had a feast on offer with workshops starting on the Saturday (2 July 2010); conference sessions, workshops, trade show and posters throughout the next few days; and concluding with workshops again on the Thursday.

Botrytis bunch rot a winner for some

Katie Dunne, PhD Candidate of the University of Tasmania, was announced the winner of the Wine Innovation Cluster Best Student Poster Prize at the 14th Australian Wine Industry Technical Conference, held in Adelaide, South Australia 3 8 July 2010.

Ms Dunne’s poster presented the results of her research into botrytis bunch rot a disease affecting grapes particularly in cool climate wine regions causing losses in grape yield and wine quality. An experiment examining the spread of the disease indicated that there was little secondary spread of the botrytis infection from the initial location of the disease within a bunch of grapes to other grape bunches.

Supervised by Dr Katherine Evans of the Tasmanian Institute of Agricultural Research at the University of Tasmania, and in collaboration with Dr Rob Bramely of CSIRO Sustainable Ecosystems, Ms Dunne plans to continue this research, examining the secondary spread of botrytis bunch rot in other vineyards.

Ms Dunne was awarded $1000 for her poster and thanked the Wine Innovation Cluster for its support of students presenting posters during the conference, saying “Winning the prize topped off what was a great week for me as there were lots of other great student posters”. The prize was presented to Ms Dunne by Dr Stuart McNab, Chair of the Wine Innovation Cluster and Director-Wine Production Australian and New Zealand of Fosters Group.

The Wine Innovation Cluster is a synergy of four leading grape and wine research agencies; The Australian Wine Research Institute, CSIRO Plant Industry, SARDI and the University of Adelaide, working in collaboration to deliver outcomes for the Australian wine industry.
