Sensory profiles of Shiraz wine from six Barossa sub-regions: a comparison between industry scale and standardised small lot research wine making


Aims: The Barossa wine region in South Australia comprises six sub-regions and is renowned for its Shiraz wines. However, there is no comprehensive documentation of the distinctive sensory characteristics of wines from these sub-regions.

Methods and Results: Shiraz wines from the six Barossa sub-regions (Central Grounds, Eastern Edge, Northern Grounds, Southern Grounds, Western Ridge and Eden Valley) were evaluated blind and in duplicate using descriptive sensory analysis by a highly trained panel of 12 experienced tasters. Evaluated wines were made with either standardised small lot winemaking (40L ferments, 2018 n= 69, 2019 n=72) or commercially produced (2018 n=44, 2019 n=76). Wine samples for sensory analysis were collected directly after completing malolactic fermentation and before maturation in oak or blending. Each vintage, the two sample sets were evaluated consecutively by the same panel, small lot wines followed directly by the commercially produced samples.

Results of the canonical variate analysis showed that wines from Eden Valley were consistently characterised as being more savoury (meaty, broth) compared to the other five sub-regions, for both vintages and production methods. Unlike their industry scale counterparts, research wines from the Western Ridge sub-region were characterised as more tannic (astringent, rough) for both vintages. Less consistent separation was observed for the other four sub-regions, with wines generally being described as fruit forward, with intense dark and red fruit.


Sensory profiles of Shiraz wines from the six Barossa sub-regions revealed a small number of consistent sub-regional characteristics for both standardised and industry scale wine samples across the two vintages.

Significance and Impact of the Study: Detailed sensory profiles for research and industry scale wine can provide valuable information for producers to best showcase wine sub-regional characteristics for marketing/promotional purposes. Next, sensory profile findings will be analysed along with soil, climate, berry and wine composition data as well as information on viticultural practices in an attempt to explain sub-regional differences and identify drivers of regionality.

How to develop strategies of adaptation to climate change based on a foresight exercise?

Prospective studies raise a real intellectual interest for those who contribute to them or take cognizance of it. But they are often considered too difficult to operationalize


Wine varietal aroma is the result of a mixture of compounds formed or liberated from specific grape-aroma precursors. Their liberation/formation from their specific precursors can occur spontaneously by acid catalyzed rearrangements or hydrolysis or by the action of the yeast enzymatic activities. The influence of yeast during fermentation on the production of these volatile compounds has been widely studied however, the effect of this influence during aging is not fully understood. In order to evaluate these processes several indirect strategies have been used to study aroma precursors although they are not useful to understand the chemistry of the process.

Développement de l’appareil végétatif et maturation du raisin sur quatre sols de Pomerol en 1995

The Pomerol vineyard, located 35 km east of Bordeaux, covers around 800 ha on the left bank of the Isle. There is a system of fluvial terraces with more or less coarse gravel and pebble spreading, resting on a Tertiary substratum ranging from the Middle to Upper Eocene to the Lower Oligocene (Dubreuilh, 1993). This interweaving of terraces of varying thickness results in a brutal superposition of differentiated materials which give rise to various types of soil. Several site studies in this sector of the Libounais show significant morphological and analytical differences from one point to another (Guilloux et al ., 1978; Duteau, 1982; Van Leeuwen et al.., 1989). The distribution of the soils of the Pomerol vineyard was studied and resulted in a cartography at 1/25000th (Merouge, 1995).

Effect of abiotic stress and grape variety on amino acid and polyamine composition of red grape berries

Vines are exposed to environmental conditions that cause abiotic stress on the plants (drought, nutrient and mineral deficits, salinity, etc.). Polyamines are growth regulators involved in various physiological processes, as in abiotic plant stress responses. Stressful conditions can modify grape’s composition, and in this work, we have focused on studying the effect of abiotic stress on the composition of polyamines and amino acids in grapes. In addition, the effect of grape variety on these compounds has been studied.

Effect of soil texture on early bud burst

Notre objectif est d’étudier de façon précise les relations entre la physiologie de la vigne et le sol, en prenant en compte l’effet millésime. Nous avons plus précisément étudier la précocité de débourrement de la vigne (stade D) en fonction de la texture du sol et plus particulièrement de la teneur en éléments grossiers.
