by Rae Blair, Conference Manager Australian Wine Industry Technical Conference

The Australian wine industry came together at the Adelaide Convention Centre to be part of the Centre’s first major
conference and trade exhibition. Despite some local and international delegates being unable to attend the event due
to the problems with flights, over 1,650 delegates attended the event from 7-11 October 2001, and took part in the
activities.

Around 200 international visitors attended the conference, with the majority of these delegates being from New
Zealand and South Africa. Chair of the Conference Planning Committee, Professor Peter Høj said Whilst the program,
workshops and posters were of immense value to delegates, the ability to meet and informally exchange information with
so many national and international colleagues over four days was vitally important. This type of interaction allows
delegates to broaden their outlook and facilitate an understanding of local and global issues with consequent
opportunities to fine-tune operations in their own organisations.

A valued aspect of the conference was the high quality and variety of the 130+ technical posters. The posters covered
a range of oenological and viticultural categories, and poster prizes were awarded to the following posters:
Non-destructive measurement of white wine colour, authored by G. Skouroumounis, M. Kwiatkowski and E. Waters from
The Australian Wine Research Institute; Mechanisms of copper mediated oxidation of (+)- catechin in synthetic white
wine authored by A. Clarke and G. Scollary from Charles Sturt University; and a range of wine microbiology posters
authored by J. Eglinton, E. Bartowsky, J. Bellon, P. Costello, G. Currie, M. de Barros Lopes, G. Fleet, L. Francis,
A. Heinrich, P. Henschke, K. Howell, V. Jiranek, M. Kwiatkowski, P. Langridge, J. McCarthy, A. Pollnitz, A. Markides
and B. van Wegen from a range of Australian institutions.

The 72 workshops were well attended with over 1,900 places being sold. The Workshop Coordinator, Peter Godden
said It was a massive undertaking to mount 72 workshops, and I am really pleased with the way the workshops
were conducted due to the input from convenors and presentors. At the outset, we were not entirely sure as to
how well the industry would embrace the concept, however, we were delighted with the response. So many
delegates found one or more workshops that they wished to attend, and many delegates were able to attend multiple
workshops.
Conducting so many workshops proved to be a huge logistical task, from clearing international
wines through customs to washing the cardboard smell from thousands of wine glasses, to ensuring delegates were
out of the formal sessions, fed and onto one of the many buses for their trip to the workshop venue, and more.
Pulling off such a task successfully required us to gather a group of committed individuals.
We were fortunate to be able to secure the services of Trudy Goode and Ella Robinson as my main supporters,
but also a large number of staff from The Australian Wine Research Institute worked some very long hours to ensure
the event was a success.
Peter remarked. Many of the workshops sparked lively debate amongst attendees.
Peter added Some workshops such as the Ethical issues facing winemakers – a discussion will result in minutes
being prepared, which will be circulated to the attendees and to the major wine industry bodies. It is pleasing
that we were able to provide workshops that filled an industry need, and may have a positive impact on the
industry’s future.

Presentations in the formal program were well attended in the main auditorium which was held from Sunday,
7th October to Wednesday, 10th October. Members of the Conference Planning Committee were pleased
overall with the presentations and the way the sessions had turned out,
noted Chair, Peter Høj, it
is difficult for me to say which particular session was the most valuable, as quality presentations were evident in all
sessions. However, based on the views of many delegates one could probably identify Session 6 (Chaired by
Louisa Rose) Application of sensory science for product development as the most thought-provoking session,
overall.
Dr Terry Lee from E. & J. Gallo, and Jane Robichaud, from Beringer Blass Wine Estates, gave presentations
with theories of mapping consumers by their taste/preference, not just simply by their usual demographics.
The whole concept of using sensory science as a primary aid to developing products is an exciting area which
would appear to be a valuable commercial tool,
said Høj. Dr Leigh Francis presented Characterising ‘in mouth’
sensory properties of red wine, which came from research undertaken by The Australian Wine Research Institute,
in collaboration with Adelaide University. From this research, a ‘mouthfeel wheel’ has been developed which
identifies and defines standard terminology to describe the feel of a wine in-mouth. The ‘mouthfeel wheel’
can be an important tool for winemakers to use in product development, where the winemakers are able to identify
in-mouth sensations more readily and use common terminology to facilitate communication and understanding,

says Høj. Professor Helmut Guth from the University of Wuppertal presented aspects of his seminal work on the
reconstruction of varietal flavour in white wines and provided further very hard evidence for the ‘dulling’
effect alcohol has on the perception of individual aroma compounds. Paradoxically, we might find that in our
quest to ripen fruit to maximise the concentration of fruit characters, this benefit is annulled by the consequent
increase in ethanol concentration in the final wine. Høj summarised The session was completed by an eloquent
presentation by Brian Walsh from Yalumba Wines on the Australian wine show system, and its relevance to our
modern industry.

The formal program was supplemented with an oenological and a viticultural colloquium. These colloquia were
developed from excellent poster abstracts we had received,
said Høj We were able to put together two
colloquia with topical presentations which generated a lot of interest.

The Conference banquet dinner was held on the Tuesday evening with 820 attendees. The food and fine
Australian wine were of an excellent standard.

Run alongside each Technical Conference is a trade exhibition, and this year’s exhibition was the largest ever
held with a Technical Conference. We had 178 exhibitors completely fill the newly expanded facility in Adelaide
and, unfortunately, we had to turn some exhibitors away, as we had sold the entire space. The exhibition was open
from Sunday night through to Thursday evening, and was open to delegates and non-delegates. It was pleasing to see
so many of the suppliers participating in the exhibition, and the companies endeavouring to achieve maximum
information flow to delegates. Many went to great lengths to ensure their display really stood out from the crowd,
which added to the festival atmosphere. The trade exhibition is an important component of the whole event, and it
provides a great opportunity for delegates and non-delegates alike to view, in the one venue, a wide range of
products and the latest innovations available that support the wine industry.

Professor Høj remarked upon the financial support provided by the Conference sponsors. This type of event is
impossible to mount at the low registration fees we charge, without the strong support of our sponsors,
he
said It is really important for students to attend the event, as they are the future of the industry, so our
sponsors allowed their registration fee to be heavily subsidised.
Professor Høj acknowledged the valued
support from the following sponsors: Netafim Australia, Vinpac International, Amorim, Seguin Moreau, Chr Hansen,
The Stephen Hickinbotham Memorial Research Trust, Winetitles and the Grape and Wine Research and Development
Corporation.

Being able to bring together such a large number of Australia’s wine technicians, and present to them such
a feast of knowledge, in a variety of forms, was remarked upon by many international visitors,
said Høj,
There are few comparable events on the world wine calendar.
