The vascular connections in grafted plants under examination

Aims: Decreasing longevity of vineyards due to the increase in the infection of different grapevine trunk diseases is a growing concern, and could be related to the quality of grafting. The main aim of this study was to evaluate the use of xylem hydraulic conductivity measurements as a potential indicator for the quality of vascular connections […]

The effect of different irrigation regimes on the indigenous Cypriot grape variety Xynisteri and comparison to Sauvignon blanc

Aims: The aims of this study were to (1) assess the response of the indigenous Cypriot variety Xynisteri to different irrigation regimes and (2) compare the performance of Xynisteri to Sauvignon Blanc grown in pots with different irrigation regimes. Methods and Results: The investigation involved two irrigation trials conducted in Lemesos, Cyprus during the 2019 season. Irrigation […]

Have the best Bordeaux wines been drunk already? A reflection on the transient nature of terroir, using case study Australia

Aim:  The aim of this paper is to demonstrate that the meaning of terroir should be regarded as transient. This is because climate, one of the principal components of terroir, is changing with time, and can no longer be assumed to be constant with fluctuations about a mean. This is due to the climate crisis. Methods and Results: The paper […]

Regulated deficit irrigation and crop load interaction effects on grape heterogeneity

Aim: To investigate the interaction effects between irrigation and crop load and the resulting impact on grape heterogeneity within a Geographical Indication in South Australia.  Methods and Results: Cabernet Sauvignon grapes were sampled at the time of harvest from the Coonawarra Geographical Indication where full and sustained deficit irrigation and crop load manipulations were implemented as a […]

Terroir in Tasting: A sensory approach for marketing fine Australian wines of provenance as memorable experiences

Aims: Establishing an image of fine wine through the Geographical Indication (GI) system is of interest to the Australian wine sector. Beyond provenance, the sensory experience of fine wine is often linked to consumption with appropriate foods. For this purpose, studies were undertaken to understand consumer perceptions of what constitutes a fine wine, which sensory and […]

Potential application of indigenous Pichia kluyveri for enhanced wine aroma quality

Aims: In previous work, five indigenous Pichia kluyveri strains, GS1-1, FS-2-7, HS-2-1, C730 and C732, were isolated and selected from spontaneous fermented wines from Ningxia and Gansu. The aims of this study were to 1) evaluate resistance of these strains to environmental stressors that may restrict their growth and the progress of alcoholic fermentation; 2) Investigate their fermentation dynamics; […]

Plant nitrogen assimilation and partitioning as a function of crop load

Aims: The optimization of nitrogen use efficiency (NUE, i.e. uptake, assimilation and partitioning) is a solution towards the sustainable production of premium wines, while reducing fertilization and environmental impact. The influence of crop load on the accumulation of N compounds in fruits is still poorly understood. The present study assesses the impacts of bunch thinning on […]

Vintage by vine interactions most strongly influence Pinot noir grape and wine composition in New Zealand

OENO One – Special issue Vine genetics, fruit maturity, region and vineyard are perceived as factors that strongly influence Pinot noir grape and wine composition. Our study aims to understand the relationship between grape (and ultimately wine) composition and the physical appearance and performance characteristics of a vine (i.e. vine ideotype). Our experimental approach controlled […]

Vine performance benchmarking of indigenous Cypriot grape varieties Xynisteri and Maratheftiko

OENO One – Special issue Aim: The aims of this study were to (1) formulate a baseline understanding of the performance of the indigenous Cypriot white grape Xynisteri and the red grape Maratheftiko (Vitis vinifera L.), and (2) compare these varieties to Shiraz and Sauvignon blanc grown in a Cypriot vineyard.Materials and results: The investigation involved […]
