The Wine Industry Journal is proud to present its readers with the industry’s world-first technical paper from the Australian Wine Research Institute (AWRI) about its scientists’ achievement of sequencing the wine yeast genome.
This work will put winemakers in a stronger position to use science to their advantage, will pave the way for the development of new yeast strains, potentially lead to innovative solutions to manage stuck fermentation and create wines with desired alcohol levels and flavour profiles.
Read more about the AWRI’s work in assisting Australia’s winemakers to minimise the effects on their wine from the heatwave that struck South Australian wine regions and others earlier this year, particularly in the case of stuck fermentations and preventing the onset of Brettanomyces/Dekkera infection during the maturation cycle.
The researchers at Cavitus Pty Ltd and the University of Adelaide continue to delve deeper into the capabilities of deactivating Brettanomyces/Dekkera in oak barrels using high power ultrasonics, and the detail can be found in this issue’s oak feature. In other reports, French oak specialist Seguin Moreau have worked in conjunction with the foundation Montpellier Agricultural Sciences and Sustainable Development to identify that the natural variability of wood compounds is influenced by oak species more so than oak origin. Industry consultant Mark Gishen poses questions for winemakers using large oak barrels and gives ideas for retaining wine freshness.
Respected engineers Vince O’Brien and Chris Colby lead this issue’s closures feature with insight to low molecular weight sulfur compounds and how wine faults such as reductive characters can be controlled with the selection of a closure with an appropriate oxygen transmission rate. Readers will be keen to learn more about how to optimise oxygen management during the vinification and storage of Shiraz wine through research undertaken by Nomacorc’s Stephane Vidal and Olav Aagaard.
Dr Richard Smart travelled to Georgia in August this year to assist its wine sector in recovering from the oppression of its product by Russia. Regarded as the home of Vitis vinfera, Richard found great interest in the native varieties of Georgia and Austria, which was also part of his latest travel itinerary.
There’s a lot more to discover in this issue of the Wine Industry Journal to help make quality wine and better operate your business.
