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.

UV-VIS-NIR spectroscopy as a tool for predicting volatile compounds in grape must

The wine sector is one of the most significant industries worldwide, with Spain being a leading country in wine production and export. A key factor in wine quality is its aroma, which is directly influenced by the volatile compounds present in the grape, with terpenes being among the most significant contributors.

INVESTIGATION OF FILM COATINGS AS A PROTECTIVE LAYER IN REDUCING THE ABSORPTION OF SMOKE PHENOLS INTO PINOT NOIR GRAPES

Wine grapes exposed to wildfire smoke have resulted in wines with burnt and ashy sensory characteristics¹, that are undesirable qualities in wine. In extreme wildfire events, this can lead to total loss of grape crop. Currently there are no effective solutions in the market to prevent the uptake of smoke compounds into grapes. In this study, previously developed innovative film coatings were tested to analyze their effectiveness in reducing smoke phenol absorption². Four different cellulose nanofiber-based film types were investigated.

Influence of ‘pinotage’ defoliation on fruit and wine quality

Among the different management techniques in Viticulture, which have
been developed with the purpose of optimizing the interception of sunlight, the photosynthetic capacity of
the plant and the microclimate of the clusters, especially in varieties that show excess vigor, the management of defoliation presents great importance. The defoliation consists of the removal of leaves that cover or that are in direct contact with the curls, which can cause physical damages in the berries, and aims to balance the relation between part area and number of fruits, providing the aeration and insolation in the interior of the vineyard, as well as reduce the incidence of rot in order to achieve greater efficiency in phytosanitary treatments and quality musts.

Terroir, sol et sous-sol : principes de modélisation spatiale de quelques paramètres physiques caractérisant le substrat altéré dans les régions viticoles établies sur socle ancien

For several years, the development of computer resources, and in particular of Geographic Information Systems, have allowed the emergence of a new approach to the analysis and characterization of wine-growing areas (Morlat, 1989; Laville, 1990). These methods, which make it possible to identify homogeneous areas or units of terroir, are based on crossing, statistical analysis (in particular Principal Component Analysis: PCA) and the integration of parameters describing the natural environment in which develop the vine.

METHYL SALICYLATE, A COMPOUND INVOLVED IN BORDEAUX RED WINES PRODUCED WITHOUT SULFITES ADDITION

Sulfur dioxide (SO₂) is the most commonly used additive during winemaking to protect wine from oxidation and from microorganisms. Thus, since the 18th century, SO₂ was almost systematically present in wines. Recently, wines produced without any addition of SO₂ during all the winemaking process including bottling became more and more popular for consumers. A recent study dedicated to sensory characterization of Bordeaux red wines produced without added SO₂, revealed that such wines were perceived differently from similar wines produced with using SO₂ and were characterized by specific fruity aromas and coolness1,2.
