The Autumn 2022 issue of the Wine & Viticulture Journal presents the results of Australian trials that have demonstrated how ultrafiltration can be used to manage phenolic compounds and haze-forming proteins in white wines. A second Australian-led study reveals how flash détente can be applied to differentiate red wine styles.

Also in Winemaking, Adam Keath from Wine Network Consulting discusses replacing ageing winery equipment that is no longer fit for purpose with more efficient systems.

In Viticulture, local researchers report on the results of a preliminary study which has shown there is a risk of infection by grapevine trunk disease pathogens during spring shoot thinning. Also on the disease front, the Australian Wine Research Institute provides a handy summary of the latest local and international studies on how to stop grapevine leafroll-associated virus 3 from spreading in vineyards and highlights where there are still gaps in our knowledge on its management under Australian conditions.

The Viticulture section also contains an article highlighting what growers can achieve through using the new and improved version of the VitiCanopy mobile app.

As well as our usual Alternative Varieties column, which this issue features Grenache Blanc, we also have an article on the Cypriot grape varieties Xynisteri and Maratheftiko as well as Aglianico, Barbera, Durif, Graciano, Mencía, Montepulciano, Negroamaro, Nero d’Avola and Touriga Nacional. In the latter, researchers generated sensory profiles of these varieties and then assessed their acceptance among Australian wine consumers. This article accompanies this issue’s Montepulciano tasting.”
