The primary aim of this project was to further our understanding of berry ripening and how its onset and progression are controlled by endogenous plant growth regulators (PGRs). The knowledge gained was used to develop and test methods for manipulating the timing of veraison/harvest using exogenous PGRs in both laboratory and field settings. We have demonstrated the ability to delay ripening and harvest time and increase ripening synchronicity through PGR application while maintaining similar wine sensory properties. In addition, experiments were conducted to get a better understanding of the influence of harvest time versus sugar levels on wine flavour/aroma volatiles.
Australia is a geographically large and diverse country, with grape and wine producing regions situated in diverse climatic zones, and consequently, different regions express large differences in their Research, Development and Extension (RD&E) priorities. In addition, the extension and adoption messages for particular research outputs need to be tailored for the region concerned. For this reason, the AWRI established a network of regional nodes in order to address regional RD&E. priorities; the Riverina, Tasmania and Hunter Valley nodes being the subject of this report. The report covers the period from I November 2013 to 30 June 2014. The work reported, comprising Outputs and Activities largely directed by the Grape and Wine Research and Development Corporation (GWRDC), focuses on extension and facilitated adoption of technologies which had been previously developed, and on extending existing A WRI flavour research projects via the Tasmania node. As such, this period represented a strong opportunity to extend work to a wider Australian wine industry audience, and a total of 30 workshops and seminars were staged across four states, with each event strongly attended by industry personnel. This achieved or exceeded the project's Output targets.
SenseAsia 2014: The Asian Sensory and Consumer Research Symposium, was held in SingEx, Singapore from 11th – 13th May, 2014 and attracted 268 delegates from 32 countries. It was the first sensory conference to be held in the Asian region focussing on the consumer. The research symposium consisted of oral and poster presentations and the topics covered included: • Basic processes: psychophysics and physiology • Developments in measures of food hoice/preference • Developments in sensory measures • Sensory science and health • Food choice and consumer behaviour • Cross-cultural influences on food choice • Sensometrics • Sensory and consumer research into non-food products • Applications of sensory methods This travel grant enabled Dr. Julie Culbert to attend the symposium and participate via a poster presentation entitled “Consumer Preferences for French Champagne and Australian Sparkling Wine” as well as provide an opportunity to gain new knowledge and network with expert researchers in the field of sensory and consumer science.
This travel report details outputs from attendance at the 65th American Society of Enology and Viticulture (ASEV) National Conference and 39th ASEV Eastern Section Annual meeting, held at Austin, Texas, from 23 to 27 June 2014. In addition to attending and giving a presentation (Walker et al. 2014) at the annual meeting, two symposia were attended. They were the ‘Water Use Efficiency’ Symposium and ‘Winemaking for Challenging Environments Symposium’. An overview of each Symposium program is presented in this report, plus highlights of selected presentations from the main conference program. Attendance at the meeting enabled networking with leading grape and wine researchers from the US and other countries. This included discussions with collaborators at UC Davis enabling existing collaborations to be progressed and new collaborations to be discussed.
A new web-based program, Know Your Numbers, Know Your Risks (KY#), was developed and launched to Riverland growers on the Riverland Wine internet portal. This program supersedes other tools available to the sector, to benchmark vineyard inputs and costs, and assess economic viability of businesses. The program supports growers’ decisions on profitability for their whole farm, varieties and individual patches using a simple input process of readily available information. It delivers a meaningful, true net farm profit or loss figure, not distorted by cash flow or tax considerations, and contains costs and income matched to a specific crop year.
Latest work lead by Dr Fuentes with collaborations with colleagues in Australia and Chile was presented at the 29th International Horticultural Congress 2014. Specifically, four oral presentations and one poster were delivered in the following symposia: • Two oral presentations at the Sustaining Lives, sub-section: Water Scarcity, Salinisation & Plant Water Relations for Optimal Production and Quality; • One oral presentation to the Production and Supply Chain symposia:sub-section: Education, Research Training & Consultancy; • One oral presentation to the Sustaining Livelihoods, sub-section 4thInternational Symposium on Tropical Wines & International Symposium on Grape and Wine Production in Diverse Regions; • One poster in the posters section with five minutes oral presentation.
This report provides a summary of the XXVIIth International Conference on Polyphenols, jointly hosted with the 8th Tannin Conference held in Nagoya, Japan from 2 to 6 September 2014 and the outcomes of attendance at this event by Angela Sparrow, a fourth year PhD candidate from the Tasmanian Institute of Agriculture at the University of Tasmania
Continuous Improvement (CI) and its application to Australian Viticulture – The study of CI management philosophies and their value in Australian viticulture
The objective of this report is to explore the use of Cl management philosophies, within the global viticultural and agricultural scene and to determine the effectiveness of these approaches and its suitability to Australian viticultural management. This objective will be achieved by observing primary producers actively using Cl management techniques and by observing other sectors of the economy using Cl. Other sectors of the economy will be observed to understand successful adoption strategies that are applicable to Australian viticulture. Recordings of the observations will be reviewed with reference to Australian viticultural practices and practical recommendations will be conveyed to the reader with examples and recommendations suitable to Australian viticulture.
Attendance and oral presentation at the 2014 Society for Industrial Microbiology & Biotechnology meeting
Dr. Tommaso Liccioli, is a research associate at the University of Adelaide (UoA), Department of Wine Microbiology and Microbial Biotechnology (WMMB), who currently works on a GWRDC funded project named “Fit-for-Purpose Yeast and Bacteria via Direct Evolution” (UA 1302). Dr. Liccioli attended the 2014 Meeting of the Society of Industrial Microbiology and Biotechnology in St Louis, MO (USA). This year attendance was of 600 and more scientists and industry related people from all around the world. Dr. Liccioli was invited to give an oral presentation on a topic he has been working and specialized over the past few years: scaling up fermentations volume for successful deployment of novel yeast strains to the wine industry. The conference committee invited Dr. Liccioli after reading one of his publications named “Microvinification – How small can we go?”. This article was written as result of a previous GWRDC funded project (UA 05/05). During the conference, Dr. Liccioli delivered a 30 minutes talk entitled: “Hide and seek: improved microbial strains vs. scientists”. His talk generated high interest amongst the audience and Dr. Liccioli had the opportunity to discuss his research and many other related topics with several delegates during the conference.
The purpose of the travel was present my work at the 1th International Plant Proteomics Organization World Congress (INPPO2014) held in at University of Hamburg, Martin-Luther-King-Platz, Hamburg, Germany, from Sunday, August 31st to Thursday, September 4th, 2014. The conference was attended by approximately 200 delegates across 37 different countries. INPPO2014 was hosted by the University of Hamburg. About 25% of the participants were students. Twelve young researchers, including me, were awarded with travel grants. Grantees came from Australia, Austria, Brazil, Canada, Mexico, Portugal, Spain, and South Africa. During the conference, I orally presented my research titled ‘Quantitative Label-free Shotgun Proteomic Analysis of a Red Grapevine Variety Exposed to Hot and Cold Temperature Stresses’. My oral presentation highlighted the proteomic changes seen in a red grapevine variety called Cabernet Sauvignon exposed to two heat and two cold stresses. Oral sessions were well patronized and I received helpful feedback and comments from the delegates who attended the conference. The conference provided very useful insights into my current research. My principal supervisor, Prof. Paul Haynes is one of the founding members of the INPPO and this was an added advantage of my attendance at the conference. Attending the conference gave me an opportunity to meet and discuss my work with several researchers from all over the world who work on plant proteomics, thus exposing my research project to an international forum.
