ASVO Regional Directors letters

You should have recently received a letter from one of the four regional directors.
The letter was sent to all members including our current, lapsed or prospective ASVO members.
Regional Directors work closely in one of four regions to ensure that ASVO initiatives are effectively communicated to members. They are charged with strategically and sustainably growing and developing membership in their regions. They serve as the primary contact for their regions, so if you know someone who should be a member let your regional director know.
To help you get to know them, we will be profiling a region in each of the upcoming newsletters.

ASVO Director profile: Dr Tony Proffitt

Dr Tony Proffitt is the Regional Director for the combined regions of Western Australia, Queensland and Tasmania. Tony has worked in the technical, consultancy, extension and educational sectors of the Australian wine industry since 1995 and he is also a lecturer at Curtin University. Tony teaches the principles and practices of viticulture to under-graduate degree and post-graduate diploma students. He has written numerous scientific papers and industry articles and co-authored two viticulture-related text books. Tony has been a member of ASVO since 1995 and served as a member of the Australian Wine Industry Technical Conference planning sub-committee on three occasions. In 2013, he was a finalist for the ASVO Viticulturist of the Year award and a judge for the ASVO Viticulture Paper of the Year award.

Regional focus: Western Australia

There have been a few peculiarities to the growing season in WA this year. August and September were unusually warm/dry months across all regions which resulted in an early budburst. This was followed by cold and windy conditions during spring, resulting in delayed, and in some cases uneven, flowering. As a consequence, some white varieties (e.g. Chardonnay) and red varieties (e.g. Cabernet Sauvignon) had poor set and ‘shot’ berries are typical within bunches this season. The Frankland area within the Great Southern region experienced some uncharacteristically bad weather in late October that resulted in many growers losing a significant percentage of their crop to a short, intense hail storm.
Vintage commenced earlier than usual for Chardonnay, Semillon and Sauvignon Blanc in the Swan Valley, Geographe and Margaret River regions. For all regions, yields for white varieties appear to be lower than average due to low bunch weights. However, winemakers are saying that fruit quality is very good as ripening has progressed evenly through what continues to be a warm, and particularly dry, summer. Bird pressure from silver eye is normal in the Margaret River region but this season parrots, wattle birds and crows have joined in. This, together with higher than normal humidity, and hence some late season powdery mildew, is causing some challenges this vintage.
The Swan Valley has finished vintage apart from some fruit that is destined for fortified wine production. In the Geographe and Margaret River regions, most white varieties and some early ripening red varieties have been picked. In the cooler Great Southern region, vintage has started with most of the Chardonnay now safely in the wineries.

Australian Wine show technical advisory group

The ASVO has played an important role in the development of Best Practice Recommendations (BPR) for the Australian wine show system. In 2004 ASVO published recommendations for Wine Shows developed by an industry based ASVO Wine Show Committee to act as guidelines for all Australian wine shows to assist them in their objectives of improving and promoting the wine quality and style offering of the Australian Wine industry.
Ten years on, the ASVO and the wider wine industry believes it is timely to review and update these recommendations as well as consider issues not addressed in the 2004 review. As such, the ASVO has formed an industry based Wine Show Technical Advisory Group (TAG) to review, revise and update the BPRs.
The objective is to develop a single document that expresses current industry views on what constitutes best practice in the Australian Wine Show system including guidelines and recommendations.
Dr Tony Jordan (Chair of the ASVO TAG) brings considerable judging, committee and exhibitor experience to the Chair position. The ASVO has also nominated Board Member Dr Tony Robinson to act as the secretary to the TAG due to his passion for and years of involvement in the Australian Wine Show system.
Members of the TAG have been chosen to represent a wide range of industry interests. Members invited include experts from large and small companies, a range of geographic origins, trade, press, wine show committees, and the 2004 ASVO committee.

 ASVO Mildura seminar, save the date.

This year’s much anticipated ASVO Mildura seminar will be held on Wednesday the 22nd and Thursday 23rd of July in the Mildura Arts Centre.
A provisional program is now available on the seminar website.

This years seminar is better value for money than ever. We have included lunch on both days for all delegates and expanded the social program with more opportunities to network and catch up with friends and colleagues. Delegates with full registration can enjoy the welcome reception and dinner on Wednesday. The Welcome Reception and Seminar Diner will be held in the Mildura Brewery Pub. This unique, locally operated business owned by Stefano de Pieri and Donata Carrazza is inside the former Astor Theatre, an immpressive art deco building in Mildura's restaurant precinct.
Delagates with full registration will also enjoy the morning after breakfast on Thursday morning, and will be able to speak to keynote speakers face to face.

The seminars are designed to share knowledge and stimulate discussion. We encourage attendees to ask questions on the day, or submit them in advance for the presenter’s consideration.
We look forward to seeing you all in Mildura, for what will be an informative and enjoyable event.
