Investigation and information transfer from the European network about thermovinification technology for process efficiency and quality control in Australian red winemaking

  • Date Completed: 2015-07-20
  • Project Supervisor: Carew, Dr Anna

Thermovinification offers winemakers an option for rapid phenolic extraction in red winemaking. This process is widely used in Europe, particularly Germany, but has not been widely adopted in Australia. Dr Anna Carew travelled to Italy to present a thermal maceration poster stemming from AGWA-funded microwave maceration (UT1301) research at the In Vino Analytica Scientia meeting in Trentino, Italy. Dr Carew also visited in Germany, Italy, France and UK to learn about thermovinification practices and research, winemaking innovation, and to develop a research network in Europe. Key outcomes from the travel were: extensive tour of winery operations and innovation at Schloss Affaltrach (Obersulm, Germany) and 7xwinery tours in Southern Germany, Northern Italy, United Kingdom; an EOI submitted for the 16th AWITC on thermovinification; development of 2xdraft proposals for joint international research (‘Thermovinification – Australia/Germany’; ‘Pinot noir Provenance – ~6xcountries’); and an invitation for oral presentation and a microwave wine tasting booth  at the 2016 ICCWS (Plumpton, UK).

Attendence & Presentation at ISSY 31: 31st Intenational Specialised Symposium on Yeast “Yeast Fermentation: from Genes to Application Aspects”, Vipava and Nova Gorica, Slovenia 2014.

  • Date Completed: 2014-10-12
  • Project Supervisor: Peter, Ms Josephine

Josephine Jasmine Peter is a PhD student working on Prototrophic deletion libraries to identify nitrogen related genes in wine and laboratory yeast. The purpose of her travel was to participate and present the project outcomes at the ISSY31: International Specialised Symposium on Yeast held in Slovenia, from October 9 – 12, 2014. The meeting broadened her knowledge on yeast research. Attendance at the conference also allowed networking with other yeast researchers and guest speakers from all over the world.

Presentation and participation at the 1st International Symposium on grapevine roots in Rauscedo (Italy) and visits to the universitities of Bologna and Gelsenhelm

  • Date Completed: 2015-06-26
  • Project Supervisor: Holzapfel, Dr Bruno

The visit of the University of Bologna allowed discussions on viticulture and grapevine nutrition between Bruno Hotzapfel, Prof. Adamo Rombolà and his research group and the visits of four wineries in the Emilia-Romagna wine region. Attending the International Symposium on grapevine roots provided the opportunity to gain knowledge of the current efforts in root research and to present a paper on recent research titled 'Effect of N and water supply on xylem composition in Semillon and Riesling'. At the Geisenheim University in Germany discussion and meetings were held with Prof. Manfred Stoll, Prof. Otmar Löhnertz and others in relation to plant nutrition and carbohydrate physiology. Two articles were published on grapevine nutrition and the knowledge gained from participation in the Symposium is being incorporated in seminars and lectures.

Travel – Internship at ISVV (Bordeaux, France) to learn ew sensory methods

  • Date Completed: 2015-06-26
  • Project Supervisor: Antalick, Dr Guillaume

This travel bursary linked to the AGWA funded project (NWG 1301) about “optimising grape quality and value to improve vineyard profitability and sustainability” was provided to achieve three major aims. The first was to learn a new methodology to investigate the “perceptive interactions” occurring between aromatic compounds in wines. It is a new concept in oenology used to investigate wine aroma perception. To our present knowledge this approach has never been undertaken before for studying Australian wine aroma. Therefore the first objective was to learn about this concept from the world leaders regarding this topic in order to transfer the knowledge in Australia via NWGIC. The second was to apply this new approach to Australian Cabernet Sauvignon as it is one of the varieties targeted in the AGWA project. The third was to interact with grapevine and wine researchers in Bordeaux in order to open new perspectives of collaboration to bring value to the project NWG 1301.

Participation in the 7th International Grapevine Downy and Powdery Mildew Workshop

  • Date Completed: 2014-10-30
  • Project Supervisor: Petrovic, Ms Tijana

Dr Tijana Petrovic attended the 7th International Workshop on Grapevine Downy and Powdery Mildew in Vitoria-Gasteiz, Spain, 30 June - 4 July 2014. The workshop was held in the Europa Palacio de Congresos, Vitoria-Gasteiz. She presented a poster and co-presented an oral paper. New information on the epidemiology, disease detection and forecasting, plantpathogen interaction, resistance and breeding and disease management of the diseases was presented in 34 papers and 19 posters. New information on qPCR (limits of detection and quantification) and hyperspectral imaging has been incorporated into current research project. The article "International research on downy and powdery mildew" (Scott et al. 2015) has been prepared for publication in The Australian & New Zealand Grapegrower & Winemaker Magazine.

Wine Tasmania Extension Support

  • Date Completed: 2015-06-30
  • Project Supervisor: Sanderson, David

Wine Tasmania identified a gap in the regional capacity to co-ordinate and deliver extension activities and liaise between the wine sector and government and research bodies. Wine Tasmania employed an experienced viticulturist as an Industry Development and Extension Officer to collect, analyse and disseminate information, implement the AGWA Regional program, conduct an annual vintage survey, represent the Tasmanian wine sector on state and national committees and ensure research findings are extended to groups and individuals through on-site visits.

Determination of Key Aroma Compounds in Australian Rosé Wine

  • Date Completed: 2015-07-30
  • Project Supervisor: Wang, Jiaming

The 9th In Vino Analytica Scientia Symposium was held in Trentino Alto Adige (Italy) from 14th to 17th July 2015. Approximately 250 registered delegates representing more than 30 countries attended the conference. The conference covered up-to-date knowledge on excellence in analytical science of grapes, wines and spirits: • Chemical analysis and composition of grapes, wines and spirits (2 sessions) • Chemical and biochemical reactions • Metabolomics, Chemometrics and Authenticity of products • Sensory analysis The travel grant provided by AGWA allowed Mr Jiaming Wang to attend the IVAS 2015 conference and present the poster presentation titled “Comprehensive study on Australian dry rosé wines – characterisation of chemical and sensory profiles”. The grant also gave Mr Wang the opportunity to visit two laboratories in Europe, being those of Professor Rémi Schneider’s group in Montpellier, France, and Professor Vicente Ferreira’s group in Zaragoza, Spain. The travel inspired Mr Wang by connecting with great minds, helped him develop professional networks and allowed for the formulation of more ideas about his research.

  • Project Supervisor: Moss, Sarah

Sarah Moss presented a poster entitled “Auxin signalling and grape development” at the annual meeting for the American Society of Plant Biologists – Plant Biology 2015 in Minneapolis, Minnesota, USA. Attending the conference provided an excellent opportunity to hear some of the most up-to-date global research and to network with a wide-range of researchers for potential future collaborations. Visiting the University of California Davis also allowed for this, as well as exploring their new viticulture and oenology facilities.

Incubator initiative: Improving vineyard water efficiency by addition of biochar derived from grape stalks and vineyard prunings

  • Date Completed: 2015-07-24
  • Project Supervisor: Muhlack, Dr Richard

The Australian wine sector generates substantial quantities of vineyard biomass waste including vineyard prunings and stalks. The objective of this project was to pyrolyse these materials to produce biochar, and then characterise the treatment effects on biochar physical properties and water-holding capacity. Biochar addition to sandy vineyard soils may improve water holding, however further testing is required. Vineyard pruning biochars displayed vastly superior phosphorus adsorption compared with other studies and may have substantial economic value as a slow release fertiliser. Further research to explore regional effects and optimisation opportunities is recommended.
