Abstract

All about “Australian grapevine stories”

Trailer: Australian grapevine stories

Narrator Andrew Caillard MW explores the wonderful and surprising story of grape vines in Australia. It starts with the ambitions of Georgian England and takes the listener on a four-part journey through the Victorian age, Federation and contemporary times. This easy listening, unstuffy and well-researched four-part series was recorded especially for the 13th Terroir Congress.

 

This trailer introduces the podcasts and acknowledges the key people behind the project.

Part 1: 1788 to 1820s – A race to the other side of the world

Ambitions for a wine industry in New South Wales were caught up in the British Government’s aspirations of expanding trade routes and wealth creation. From 1788 to the 1820s, colonial wine was a cottage industry but the pioneers from Sir Joseph Banks in London to John Macarthur and nurseryman Thomas Shepherd in Sydney believed that Australia could become the France of the Southern Hemisphere. But the first years of settlement were not without political troubles and serious economic challenges.

Part 2: 1820s to 1855 – Convictions and transportation

There were many new importations of vitis vinifera during the 1820s to 1855. The most famous was the remarkable collection of grape vines imported into New South Wales by James Busby in 1832. William Macarthur of Camden Nurseries becomes a highly influential figure supplying many of Australia’s earliest pioneers with vine stock material for planting in the Australian colonies. This was also the dawn of the steam age, the beginning of the gold rush (1851) and the Universal Exhibition in Paris (1855).

Part 3: 1855 to 1960s – Grand dreams and boom-bust-boom

Fortunes were mixed after the great promise of the 1860s and early 1870s. Many of Australia’s greatest 19th Century vineyards were planted during this time. Economic, social and agricultural challenges hampered progress. The arrival of Phylloxera in Victoria in 1875 was met with a scorched earth policy. But South Australia’s quarantine laws protected the vast plantings of grape vines especially around Adelaide, McLaren Vale, Barossa and the Clare Valleys. Australian Burgundy boomed in the 1880s and 1890s. After the Second World War plant breeding programmes were introduced to improve colonial vinestock material, while only a trickle of new clones and selections were permitted into Australia.

Part 4: 1970s to Today – A step back into the future

The golden period of modern wine was enabled by the dreams and hard work of past generations. While 19th Century vinestock reflects the romance and dramas of the Georgian Victorian ages, new material is required to build on those extraordinary efforts. The pursuit for ideal chardonnay clones led to the arrival of 19th Century Californian vinestock material into Australia. In the meantime, alternative varieties might not be that alternative given their history in Australia. Australia’s colonial vinestock heritage is one of the four corner stones of our modern wine industry.

New Insights into Wine Color Analysis: A Comparison of Analytical Methods and their Correlation with Sensory Perception

wo spectrophotometric methods are recommended by the Organisation Internationale de la vigne et du vin (OIV). The first is the method after Glories, were the absorbances at 420 nm, 520 nm and 620 nm are measured (OIV 2006a).

Analysis of the interaction of melatonin with glycolytic proteins in Saccharomyces cerevisiae during alcoholic fermentation 

Melatonin is a bioactive compound with antioxidant properties, that has been found in many fermented beverages, such as beer and wine [1]. Indeed, it has been shown that yeast can synthesize melatonin during alcoholic fermentation, although its role inside the cell, as well as the metabolic pathway involved in its synthesis, is still unclear [1]. Recent studies showed that during fermentation, melatonin interacts with different proteins of the glycolytic pathway in both Saccharomyces and non-Saccharomyces yeast, for instance glyceraldehyde 3-phosphate dehydrogenase, pyruvate kinase or enolase [2].

Machines and fire: developing a rapid detection system for grapevine smoke contamination using NIR spectroscopy and machine learning modelling

Bushfires are a common occurrence throughout Australia and their incidence is predicted to both rise and increase in severity due to climate change. Many of these bushfires occur in areas close to wine regions, which receive different levels of exposure to smoke. Wine produced from smoke-affected grapes are characterised by unpalatable smoky aromas such as “burning rubber”, “smoked meats” and “burnt wood”. These smoke tainted wines are unprofitable and result in significant financial losses for winegrowers.

Reduced berry skin epi-cuticular wax and cutin accumulation associates with a genomic deletion and increased polyphenols extractability in a clone of Tempranillo Tinto 

Tempranillo Tinto (TT) is the third-most planted red wine variety in the world, and it is mostly grown in the Iberian Peninsula. Spontaneous somatic variation appearing during vegetative propagation can be exploited to improve elite varieties as Tempranillo Tinto, including the selection of new phenotypes enhancing berry quality. We described previously that a somatic variant of TT with darker fruit color, the clone VN21, exhibits increased extractability of polyphenols during the winemaking process. To unravel the molecular mechanism underlying this phenomenon, we performed whole-genome resequencing to compare VN21 to other TT clones, revealing a 10 Mb deletion in chromosome 11 that likely affected only the L1 meristem cell layer of VN21 and tissues derived from it, such as external cell layers of berry skin.
