Terroir effects on the response of Tempranillo grapevines to irrigation in four locations of Spain: grape and must composition


This work discusses the effects of soil and weather conditions on the grape composition of cv. Tempranillo in four different locations of Spain, during the 2008-2011 seasons. In all locations vines were pruned to a bilateral cordon, trained to VSP and under similar cultural practices. In three locations (Requena-east, Badajoz-west and Valladolid-northwest) a pre-veraison deficit irrigation strategy (DIP, where irrigation was withheld until a certain level of vine water stress was reached, and afterwards was irrigated at full ETc) was compared to rain-fed vines; while in the fourth location (Albacete-central), DIP was compared to a sustained deficit irrigation (SDI, irrigated at 33% ETc season long). In all locations, except in Valladolid, irrigation at full ETc season long was also studied. Using common analytical procedures, total soluble solids (ºBrix), malic and tartaric acids, pH, total acidity, total phenolics compounds (TPC), anthocyanins and tannins were determined, and the ratios Ant/ºBrix, TPC/ºBrix and Tan/ºBrix calculated in order to compare the phenolics accumulation as function of berry sugars concentration.

Compared to Rainfed, DIP increased ºBrix in all locations and reduced the Ant/Brix ratio, except in Albacete. The effects on the other compositional parameters varied largely depending on location. Irrigation at full ETc compared to Rainfed increased TA in all sites, but practically unaffected ºBrix nor the Ant/Brix ratio, especially in Albacete and Badajoz. However, in Requena full irrigation slightly decreased ºBrix and produced the highest reduction of the Ant/Brix ratio. Thus, our results show that the effects of irrigation on the accumulation of secondary metabolites of grape composition are in large part determined by the vineyard-to-vineyard terroir characteristics.

The pinking of in white wine is the turning of color from yellow to salmon hue. White wines obtained from certain grape varieties (e.g. Chardonnay, Sauvignon blanc, Riesling, Trebbiano di Lugana) showed to be susceptible to pinking [1] that has been evaluated by an assay providing the addition of hydrogen peroxide. Even if its appearance does not seem to affect the sensory properties [2], strategies are necessary for its removal. Nowadays, the treatment with polyvinylpolipirroline (PVPP) was reported to significantly decrease the pink color [3].

The potential of multispectral/hyperspectral technologies for early detection of “flavescence dorée” in a Portuguese vineyard

“Flavescence dorée” (FD) is a grapevine quarantine disease associated with phytoplasmas and transmitted to healthy plants by insect vectors, mainly Scaphoideus titanus. Infected plants usually develop symptoms of stunted growth, unripe cane wood, leaf rolling, leaf yellowing or reddening, and shrivelled berries. Since plants can remain symptomless up to four years, they may act as reservoirs of FD contributing to the spread of the disease. So far, conventional management strategies rely mainly on the insecticide treatments, uprooting of infected plants and use of phytoplasma-free propagation material. However, these strategies are costly and could have undesirable environmental impacts. Thus, the development of sustainable and noninvasive approaches for early detection of FD and its management are of great importance to reduce disease spread and select the best cultural practices and treatments. The present study aimed to evaluate if multispectral/hyperspectral technologies can be used to detect FD before the appearance of the first symptoms and if infected grapevines display a spectral imaging fingerprint. To that end, physiological parameters (leaf area, chlorophyll content and photosynthetic rate) were collected in concomitance to the measurements of plant reflectance (using both a portable apparatus and a remote sensing drone). Measurements were performed in two leaves of 8 healthy and 8 FD-infected grapevines, at four timepoints: before the development of disease symptoms (21st June); and after symptoms appearance (ii) at veraison (2nd August); at post-veraison (11th September); and at harvest (25th September). At all timepoints, FD infected plants revealed a significant decrease in the studied physiological parameters, with a positive correlation with drone imaging data and portable apparatus analyses. Moreover, spectra of either drone imaging and portable apparatus showed clear differences between healthy and FD-infected grapevines, validating multispectral/ hyperspectral technology as a potential tool for the early detection of FD or other grapevine-associated diseases.

Characteristics of ecological production of grape and wine in Prizren’s vineyard territory in Yugoslavia

Prizren’s vineyard territory-y assigned for ecological production of grapes and wine includes 1. 200 hectares of vineyard located in five separate localities which belongs to the P KB “Kosovo vina”, Mala Krusa in Prizren. Division of vineyard territory in zones was carried out in 1974. Pertaining to the vineyards, the climate and soil conditions have been studied and determined as well as topographie establishing of vineyard boundaries.


Lipids are a diverse group of organic compounds essential for living systems. They are vital compounds for yeast which makes them an important modulator of yeast metabolism in alcoholic fermentation. This study presents a comprehensive lipidome analysis of wine samples from the Vitis vinifera L., Maraština. The fermentation trails were set up in monoculture with different indigenous yeast strains selected from a collection of native yeasts established at the Institute for Adriatic Crops and Karst Reclamation in 2021, previously isolated from Croatian Maraština grapes: Metschnikowia pulcherrima, Metshnikowia sinensis/shanxiensis , and Metschnikowia chyrsoperlae.

In addition to studies on the edaphic and landscape characteristics of the environment (Dolédec, 1995), the characterization of the physiology of the vine and of parasitism during its vegetative cycle represents an essential component of knowledge and management of the terroirs.
