History and innovation of terroir

Making sense of a sense of place: precision viticulture approaches to the analysis of terroir at different scales

OENO One – Special issue Traditional ‘terroir zoning’ has largely relied on heuristic ‘expert’ opinion coupled with approaches to land classification based on thematic mapping to describe the influence of soil conditions and climate on wine composition. Recent advances in geographical information systems (GIS) and digital mapping have enabled more ...

Recent advancements in understanding the terroir effect on aromas in grapes and wines

OENO One – Special issue Terroir is about the link between wine and its origin. It has long been understood by sensory evaluation that the taste of wine from a given variety can be related to its origins. Specific organoleptic characteristics of wine are influenced by environmental factors such as ...

In search of the taste of terroir – a challenge for sensory science

The definition of terroir has evolved throughout history, from something clearly negative in the XVIth-XVIIIth century to a complex multi-parametric construct with positive connotations but also with many scientific unknowns. Terroir has always been linked more or less explicitly to the sensory properties of the resulting products. Wine consumers have ...

Comparison between satellite and ground data with UAV-based information to analyse vineyard spatio-temporal variability

OENO One special issue Currently, the greatest challenge for vine growers is to improve the yield and quality of grapes by minimizing costs and environmental impacts. This goal can be achieved through a better knowledge of vineyard spatial variability. Traditional platforms such as airborne, satellite and unmanned aerial vehicles (UAVs) ...

Comparing the chemical and sensory consequences of grapevine smoke exposure in grapes and wine from different cultivars and different wine regions in Australia

Aim: This study aimed to benchmark the chemical and sensory consequences of grapevine exposure to smoke, by comparing: (i) the concentration of volatile phenols and volatile phenol glycosides in control and smoke-affected grapes from different cultivars and different wine regions; and (ii) the chemical and sensory profiles of wines made from ...

Preserving wine typicity in a climate change scenario: Examples from the Willamette Valley, Oregon

Aims: Wine typicity is defined as a reflection of varietal origins, cultures and traditions of the wine. These aspects are many times also extremely important when considering a wines quality. However, as climate change occurs the typicity of wines may also change. With the long history of winemaking it is possible ...

Understanding provenance and terroir in Australian Pinot noir

Aims: This study aimed to (1) characterise colour and phenolic profiles of commercial Australian Pinot noir wines, (2) understand regional drivers of sensory and volatile profiles of commercial Australian Pinot noir wines, and (3) generate a deeper understanding of where Australian Pinot noir wines profiles sit in an international context. Methods and ...

Adaptation to climate change by determining grapevine cultivar differences using temperature-based phenology models

OENO One – Special issue Grapevine phenology is advancing with increased temperatures associated with climate change. This may result in higher fruit sugar concentrations at harvest and/or earlier compressed harvests and changes in the synchrony of sugar with other fruit metabolites. One adaptation strategy that growers may use to maintain ...

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.
