California's vineyards are coming back from the brink of disaster thanks to the winter rains

Patrick Comiskey - 05 Apr 2017

California’s vineyards — Central Coast vineyards in particular — are coming back from the brink of disaster. Record low rainfall levels, coupled with record average temperatures in an age of global warming, had left viticulture from Monterey to Ventura in a low-grade peril. The five-year drought had been so inexorable in its effects, so disruptive to seasonal cycles, that growers were having a hard time imagining what a return to normal would look like.

FameLab is an international competition which aims to nurture engagement between science and society by creating spaces for young people to find their voices and talk about their science, technology, engineering and mathematics. The project started in 2005 at the Cheltenham Science Festival in the United Kingdom and quickly became an international initiative, currently present in 26 countries worldwide thanks to a partnership with the British Council. FameLab is designed to inspire and motivate people working in science and technology to play an active role in communicating their fields to the public through the medium of a talk given before an audience in 3min. The British Council and local implementing partner Jive Media Africa are running FameLab in South Africa in partnership with the South African Agency for Science & Technology Advancement (SAASTA), a business unit of the National Research Foundation. 

The semi-finals videos was uploaded to the SAASTA website (and also YouTube). There is a voting poll on the website and we were hoping for your everyone's support and votes.

H2S and mercaptans: New discoveries

Oenoppia press release on infowine.com - 26 Nov 2015

Researchers have demonstrated for the first time that H2S and mercaptans in wine are not only present in volatile (odorous) form. They also exist in odourless complexes (with other other molecules) and are hence undetectable. Wine contains many sulphur compounds that may be released throughout its life span in bottles since these combinations are reversible.

App to help manage grapevines

http://phys.org/news/2015-10-app-grapevines.html - 26 Oct 2015

A new, free phone app developed by University of Adelaide researchers will help grapegrowers and viticulturists manage their vines by giving a quick measure of vine canopy size and density. The iPad and iPhone app uses the devices' camera and GPS capability to calculate the size and density of the vine canopy and its location in the vineyard. The aim is to help users monitor their vines and manage the required balance between vegetative growth and fruit production.

The development of the app – called VitiCanopy – has been supported by Wine Australia as part of a wider project investigating the relationships between vine balance and wine quality.

Climate change threatens European wine production

by Aline Robert, translated by Samuel White - 26 Sep 2015

The EU is the world's biggest wine producer, but a recent publication has revealed the extent to which the sector is under threat from climate change. EurActiv France reports

The harvest is already over for many Beaujolais wine makers. Early harvests have also taken producers in many other French regions by surprise. Some wine makers were concerned by the unusually hot summer, but the resulting high sugar content in this year's grapes, which guarantees a high level of alcohol in the finished product, is seen by many as a good thing. But the authors of the book Threats to wine. The challenges of climate change, Valery Laramée de Tannenberg and Yves Leers, fear the celebrations could be short lived.

He believed the disease was caused by his use of a pesticide to protect against vine trunk disease esca for more than 40 years.

Little Fly, Big Problem for Wine

Neville Galvin - 17 Mar 2015

Last year was difficult enough for vintners in many of Europe's leading wine regions, thanks to a gray, wet summer that slowed grape ripening and encouraged mildew. But they also had to grapple with a new pest during the 2014 harvest: a foreign fruit fly. Drosophila suzukii, commonly known as the spotted wing drosophila, was first spotted in Europe in 2008. And last year's weather encouraged a population swell that left grapegrowers wrestling with an unfamiliar pest. They're worried this year could bring more flies—and trouble.
