Professor Vladimir Jiranek37

Regional Director – South Australia

My 25 years of wine microbiology experience began with a PhD (University of Adelaide) undertaken at the AWRI. Our findings enabled the Australian industry to better select and apply yeasts for improved nitrogen-efficiency and reduced fermentation problems and H2S. In 1997, after appointments in the US and NZ, I returned to the University of Adelaide and joined ASVO. My team in Adelaide of 12 talented researchers interacts extensively with the Australian wine industry as well as international research groups. I convene the University’s Wine Science and Business Group, which comprises 10 outstanding academics whose expertise spans the winemaking-to-consumer spectrum. I’m privileged to have taught almost 700 oenology and viticulture graduates, many working across the global wine industry.

My most significant contribution to the ASVO was as Editor (2007-2012) of a key society output, the Australian Journal of Grape and Wine Research. Under my editorship, AJGWR successfully transitioned to an online submission system and greater online presence. It continues to be the highest ranked wine-related journal in the world.
