Winter issue of the Wine & Viticulture now available

Mark Morris, founder and managing director of Enviroeye, has some timely advice for vineyard managers in the the Winter issue of the Wine & Viticulture Journal on how to better manage the growing pressures from hotter and drier seasons and decreased water supplies .

Regular writer Erika Szymanski takes an interesting look at the science behind blending. As she writes, blending is often described as an art. But is that simply because scientific research has not yet explained how to blend precisely to achieve the best results?

Also in Winemaking, we look at some research out of Italy on the use of the antimicrobial agent ozone on winegrapes post-harvest instead of sulfties to remove smoke taint from grapes before vinification and avoid the use of sulfites in vinification. The study looked at the effect ozone treatment on anthocyanin stabilisation in red wines and colour oxidation in white wines.

The AWRI presents some interesting findings from a recent study which suggests that even the smallest differences in the temperature where wines are cellared can have a significant effect over time.

Journalist Hans Mick takes a look at the increasing array of non-wood trellis posts availabe on the market in the face of the industry’s ongoing problem of disposing of CCA-treated posts, while the CSIRO updates us on their efforts to breed the next generation of rootstocks resistant to phlloxera and root knot nematode.

Australian viticultural consultant Richard Smart has some suggestions on what the wine industry can do to help mitigate the effects of climate change.

We also present the results of our latest tasting, rosé.
