Influence of the irrigation period in Tempranillo grapevine, under the edaphoclimatic conditions of the Duero river valley

Abstract

Irrigation of vineyards is a matter of controversial arguments at areas of high quality wine production. Besides, the effects of the water in the plant are closer related to the water availability than to the irrigation regime. In this way, the criteria for irrigation timing can reach very important physiologic and productive consequences to optimize the vineyard management on each environmental situation. An experimental trial has been carried out along the period 2005-2007 in the province of Valladolid (Spain), focused on the study of modification of plant water status (leaf water potential), soil water content, physiologic activity, vegetative-productive behavior and quality expression (berry weight, sugar concentration, pH, total acidity, poliphenols concentration) of the Tempranillo variety in the Duero river valley, through the application of a moderate irrigation doses in two different periods of the vegetative cycle, on a concrete edaphic situation. The treatments applied were the following: 20% ETo from vegetative Growth stopping (G20) and 20% ETo from Veraison (V20), both irrigated until one week before harvest. The vines, planted in 1993, were grafted onto 110R and vertical trellised trained, as a bilateral Royat cordon. Vine spacing is 2.70 m x 1.40 m (2645 vines/ha).
The results have shown some differences due to the irrigation period treatments on the effects related to vine water status and soil water content, physiologic activity, vegetative development, productivity and grape quality in Tempranillo variety. In general, the earlier application of irrigation has favoured vine physiologic activity and leaf development, through the improvement of plant water status, estimated by means of leaf water potential measurement, which have consequently provoked certain increase of yield. On the contrary, the delay of irrigation until veraison stage has shown certain tendency in grape composition to increase sugar concentration, pH and poliphenols index.

SENSORY PROPERTIES IMPORTANT TO AUSTRALIAN FINE WINE CONSUMER SEGMENT PERCEPTION OF CHARDONNAY WINE COMPLEXITY AND PREFERENCE

Wine complexity is considered a multidimensional yet equivocal sensory percept. This project uncovered sensory attributes Australian Chardonnay wine consumers associate with Chardonnay wine complexity
and correlations between expert and consumer perceived wine complexity and preference. A
wine consumer test examined 6 Australian Chardonnay wines of three complexity levels designated low (LC1&2), medium (MC1&2), and high (HC1&2) by an expert panel (n = 8) using a benchtop sensory task. Consumers (n = 81) rated their perceived liking using a 9-point hedonic scale; wine complexity with a 5-point scale anchored “low”, “low-medium”, “medium”, “medium-high”, and “high” and lastly, profiled the wines using Rate-All-That-Apply (RATA). Psychographic segmentation with the Fine Wine Instrument
(FWI) generated three segments; Wine Enthusiasts (WE n=29), Aspirants (ASP n=40) and No- Frills (NF n=12).

A nutraceutical based on mediterranean diet with omega-3 fatty acid and resveratrol from grapewine counteracts ocular degenerative diseases

More recently, studies have shown that polyphenols could also prevent or improve vision in patients with ocular diseases and especially Age-related macular degeneration (AMD) which is an eye disease characterized by damage to the central part of the retina, the macula, and that affects millions of people worldwide. Despite therapeutic advances thanks to the use of anti-vascular

Vineyard management practices to reduce sugar content on ‘Monastrell’ grapes

Climate change is resulting in more dry and hot summers, accelerating grape ripening and increasing berry sugars concentration. This results in wines with a higher alcohol content, which has a negative impact on wine quality, as well as, on consumer health. Agronomic practices that minimize these effects on berry composition and, consequently, on wine quality must be defined. In this work, different management practices have been assessed on rainfed ‘Monastrell’ grapevines in Jumilla (Murcia, Spain) from 2021 to 2023 vintages. Mulching, shading, application of kaolin and different types of pruning were evaluated, among others field adaptation practices.

EFFECT OF WHOLE BUNCH VINIFICATION ON THE ABUNDANCE OF A SWEETENING COMPOUND

In classic red wine-making process, grapes are usually destemmed between harvest and the filling of the vat. However, some winemakers choose to let all or a part of the stems in contact with the juice during vatting, this is called whole bunch vinification. For instance, this practice is traditionally used in some French wine regions, notably in Burgundy, Beaujolais and the Rhone Valley. The choice to keep this part of the grape is likely to affect the sensory properties of wine, as its gustatory perception1,2.

Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered.
