A list of ASVO Fellows can be found at https://www.asvo.com.au/asvo-fellows-society.&lt;/p&gt;&lt;p&gt;Sue joined Wynns Coonawarra Estate in 1993. Five years later, she became the winery's first female chief winemaker. Sue worked closely with viticulturist Allen Jenkins to rejuvenate the old vines and reconstruct the vineyards, heralding a new era for Wynns and the entire Coonawarra region. Sue and her team are continuing to adopt more sustainable viticulture methods, including better soil moisture management and maintaining a stronger focus on vine health. Sue has contributed to the research, development and assessment of new clones and rootstocks for the next generation of Cabernet Sauvignon in Coonawarra since 2004—starting with 50 vintages of Wynns Black Label Cabernet. This sample set has provided an unparalleled insight into tannin evolution for Australian wine.

She was pivotal to the development of Provenance classes (initiated at the Adelaide wine show during Sue's chairmanship). Sue has judged at many regional, capital city and international wine shows, mentoring associate judges, providing feedback to committees and judging collaboratively with her peers. She has been involved in the Australian Cabernet Symposium, including hosting it in Coonawarra three times. Sue has enthusiastically provided data, opinion and wine to researchers, panel leaders and suppliers to participate in the Australian Wine Industry Technical Conference. Sue was President of Coonawarra Vignerons immediately before the merging of the Vignerons and Grape Grower Associations.
