Influence of weather and climatic conditions on the viticultural production in Croatia

Abstract

The research includes an analysis of the impact of weather conditions on phenological development of the vine and grape quality, through monitoring of four experimental cultivars (Chardonnay, Graševina, Merlot and Plavac mali) over two production years. In each experimental vineyard, which were evenly distributed throughout the regions of Slavonia and The Croatian Danube, Croatian Uplands, Istria and Kvarner and Dalmatia, the dates of occurrence of the following phenophases are recorded: swelling and opening of buds, the beginning of flowering, the pattern and technological maturity of grapes (harvesting), representing BBCH phases 09, 68, 83 and 89. By analysing multiannual data on harvest deadlines and qualitative parameters of grapes from different regions of Croatia and comparing them with climate data for the same period, we found that the main climatic components affected grape production. In addition, the meteorological data of the Croatian Hydrometeorological Institute also identified trends in Huglin’s index, index sum of the effective temperatures according to Winkler, cold night index and the average air temperature index in the vegetation, for the period 1961-2018. Maps of the four agroclimate indices in 1989-2018 and comparisons with the reference period 1961-1990 indicated climate change over the last 30 years. Due to the increase in the Huglin index of 200 -300°C throughout Croatia, it is possible to change the grapevine varieties in continental Croatia, i.e. planting black wine varieties that need a greater amount of heat, and the possibility of raising winegrowing plantations of early grape varieties in mountain Croatia below 600 m above sea level. The purpose of this research is to increase the adaptability and reduce the vulnerability of Croatian viticulture related to the impact of climate change on grape and wine production through the revision of existing and possible proposal for the establishment of new wine-growing zones in Croatia.

Mapping climate and bioclimatic indices at high-resolution in vineyard regions

Many of the world’s vineyard regions are located in regions of complex terrain, with the result there is significant local climate variation.

Effects of the addition of yeast derived products during aging in chardonnay sparkling winemaking

From the beginning of the yeast autolysis process, several interesting intracellular and cell wall constituyents are released to the media providing different characteristics to the wine, being this process extensively studied in sparkling wines due to their important contribution to their properties (1-2). Yeast derived products (YDs) try to emulate the natural yeast autolysis compounds release enhancing the organoleptic characteristics of resulting wines (2-3). This study is a comprehensive evaluation of the impact of the addition of different YDs added to base wine on the chemical, physical and sensory characteristics of the resulting sparkling wines. METHODS: Chardonnay base wine was employed to carry out this study. Three experimental YDs were added at 5 and 10 g/hL to the tirage liqueur: a yeast autolysate (YA), a yeast protein extract (PE) and an inactivated dry yeast from Torulaspora delbrueckii, (TD), and two commercial specific inactivated dry yeast: OPTIMUM WHITE® (OW) and PURE-LONGEVITY®(PL). After second fermentation, measurements were carried out after 3, 6, 9 and 18 months of aging on lees. General enological parameters, proteins, polysaccharides (HPLC-DAD-RID), volatile compounds profile (GC-MS), foaming characteristics (Mosalux), and descriptive sensory analyses were carried out.

Evaluation of the impact of different amelioration techniques on the chemical composition and sensory characteristics of smoke impacted wines

AIM: The increasing incidences of wildfires in wine grape growing regions pose a significant risk. Persistent exposure to smoke can compromise the quality and value of wine grapes and adversely affect wines made from smoke exposed grapes.

Présentation d’une méthodologie de caractérisation des terroirs et valorisation par l’étude de l’effet terroir sur la typicité et l’originalité du produit vin dans la région des Côtes du Rhône

In the global economic context, an Appellation d’Origine Contrôlée must now more than ever control the typicity and originality of the wines it produces. It is in this spirit that the Côtes du Rhône have decided to acquire the means necessary for this control.

Vegetative propagation during domestication – rooting ability of wild grapevines

The origins of plant propagation trace back to the moment of early humans’ transition from a nomadic existence to settled agricultural societies, cultivating their food.
