Current Issue – December 2019 (no. 671)

Grapegrower & Winemaker provides subscribers with access to an online version of each print issue.

For this issue’s theme on Fermentation, Alana Seabrook, from Laffort Australia, and her colleagues Joana Coulon, from BioLaffort, and Susan Erasmus, have compiled a comprehensive article on the main factors involved in stuck fermentations and how to avoid them.

Journalist Hans Mick provides an update on the development and commercialisation of the yeast being developed by the Australian Wine Research Institute to lower alcohol levels.

And, concluding the theme on fermentation, this month’s Ask the AWRI column answers some questions on the role of grape solids in white winemaking.

Also in Winemaking, the AWRI reports on a trial that looked at the influence of storage orientation of bottles of wine and temperature fluctuations on the oxygen transmission rate of commercial closures.

In Viticulture, journalist Samuel Squire chats with the company behind an on-board weighing solution for grape bin trailers that enables fruit loads to be automatically recorded as they come off harvesters.

And in Business & Technology, Kym Anderson, from the University of Adelaide and the Australian National University, and Glyn Wittwer, from Victoria University, have done some number crunching to determine the fallout from the recently-imposed US tariffs on imports of some EU wines in those countries and in Australia.
