This issue features some emerging and projected impacts of COVID-19 on the wine industry. Peter Bailey from Wine Australia reveals some early sales figures from bottleshops around the nation off the back of measures to slow the spread of COVID-19, Dean Taylor from Wine Depot finds out how wineries have tried to grow the size of the direct-to-consumer pie to take up some of the slack left by the absence of the on-trade and Kym Anderson from the University of Adelaide and Glyn Wittwer from the University of Melbourne present the results of some modelling projecting the impacts of COVID-19 on global wine markets over the next two years. 

In Winemaking, Erika Szymanski explores the latest research into the influence of sulfur on thiol compounds and aroma, Rachel Gore looks at options for reducing the use of refrigeration; and a team of researchers from the University of Melbourne reveal how artificial intelligence has been successfully applied to assess smoke taint in grapes and wine.

In Viticulture, we present the results of an Australian trial into the effect of shoot and bunch thinning on various grape and wine parameters, along with insights from a Tasmanian study into the impact of early spring frost injury at nodes of Pinot Noir on fruitfulness.

And, in lieu of our regular tasting, we compare the approaches and production practices of single-vineyard Chardonnays from two different Australian vineyards and a vineyard in the US.
