Ampelograpic and genetic characterisation of grapevine genetic resources from Ozalj-Vivodina region (Croatia)

Abstract

Context and purpose of the study– Ozalj- vivodina region is small vine growing area (only about 100 hectares of vineyards), but with significant number of old, ancient vineyards planted between 50 and 100 years ago. Trend of abandoning or replanting ancient vineyards takes place for the last 30 years. This trend results in grapevine germplasm erosion because traditional varieties are replaced with well known international varieties.Few known traditional varieties are dominantly present in ancient vineyards together with many others of unknown identity. Historical data about prevalence and characteristic of varieties on this area are very poor. For this reason, we started a project with the purpose of identification, characterization and conservation of grapevine germplasm in this area.

Material and methods – Three years study (2016-2018) included ampelographic inventarization of ancient or abandoned vineyards in Ozalj-Vivodina area. A total of 61 samples (vines) were selected for further research and identification. Identification in situ include ampelographic description by standard set of OIV (Organization Internationale de la Vigne et du Vin ) descriptors. Genetic identification was performed using nine microsatellites markers recommended by the European project GRAPEGEN06. Genetic profile of samples was compared by national and several international databases for possible matching between profiles or with other varieties.

Results – Based on microsatellite analysis of the 61 samples, 45 different genotypes were detected which were identified as follows: 18 genotypes did not match with any of the varieties from available databases; 6 genotypes were identified as traditional or native varieties from NW Croatia (Plavec žuti, Kozjak bijeli, Dišeća Ranina, Moslavac (Furmint), Plemenka (Chasselas rouge), Graševina (Welschriesling); 8 genotypes were identified as rare autochthonous Croatian varieties from other wine regions; 7 genotypes represent common varieties from other European countries (Chardonnay, Pinot Blanc, Blaufraenkisch, Sauvignon Blanc, Rkatsiteli, Pamid, Chauch blanc; 5 samples represent a rare variety identified in other European countries (for example Gaensfuesser blau) and one genotype was identified as Belina starohrvatska (syn. Gouais Blanc). It is interesting that Gouais blanc was represented with six samples from five different locations even though it was not considered to be a traditional cultivar in this area. Ampelographic study shown that dominant genotypes have white coloured berry (33), followed by red (7) and rouge (2). Three genotypes had no clusters available during research. Three genotypes have specific muscat flavour and two have a female type of flower. This research shows that Ozalj-Vivodina as a small winegrowing area has rich grapevine germplasm preserved.

Mannoproteins extraction from wine lees using natural deep eutectic solvents

Wine lees can be a good source of yeast mannoproteins for both food and wine applications [1,2]. However, mannoprotein extraction from wine lees has not yet been scaled up to an industrial scale, mainly because of the limited cost-effectiveness ratio of the methods employed at the laboratory scale [2].

Étude intégrée et allégée des terroirs viticoles en Anjou: caractérisation et zonage de l’unité terroir de base, en relation avec une enquête parcellaire

The terroir concept is presented as the basis of the A.O.C system, in the french vineyards. The “Anjou terroirs” programme aims at bringing the necessary scientific basisfor a rational and reasoned exploitation of the terroir. lt must lead to finalizing a lighter, more relevant integrated method of characterisation wich could be generally applied.

Macromolecular characterization of disease resistant red wine varieties (PIWI)

Pilzwiderstandsfähige (PIWI) are disease resistant Vitis vinifera interspecific hybrid varieties that are receiving increasing attention for ability to ripen in cool climates and their resistance to grapevine fungal diseases. Wines produced from these varieties have not been characterized, especially regarding their macromolecular composition. This study characterised and quantified colloid-forming molecules (proteins, polysaccharides and phenolics) of red PIWI wines produced in the UK. METHODS: In 2019 6 wines were made from the PIWI varieties Rondo, Cabernet Jura, Cabernet Cortis, Cabernet Noir, Regent and Cabertin grown at the Plumpton Rock Lodge Vineyard in Sussex (UK) and harvested at similar level of maturity (TSS, pH and TA). All juice was chaptalized to the same potential alcohol of 12%. Small scale winemaking (1L) was performed in quadruplicate using Bodum® coffee plungers to manage maceration [1]. Residual sugar content, pH, and titratable acidity were monitored during fermentation. For finished wines, the protein and polysaccharide content was measured by HPLC-SEC [2], while the total phenolic content was assessed using the Folin-Ciocalteau method [3]. The protein profile of the wines was further investigated by SDS-PAGE [4]. RESULTS: Fermentations (n=24) were all carried out to completion within 8 days.

SIP and save the planet: a sensory and consumer exploration of australian wines made from potentially drought-tolerant white wine grapes

In order to attenuate the effects of climate change on the ability to cultivate quality wine grape vines in Australia, it is essential to adapt to the projected less favourable Australian climate scenarios. One response may be to convert a portion of the current grapevine plantings to those varieties that demand less water and can tolerate increased heat. This investigation aimed to (i) generate sensory profiles and (ii) obtain knowledge about Australian wine consumers’ preferences and opinions of Australian wines made from potentially drought tolerant, white wine grape varieties not traditionally cultivated in Australia. A Rate-All-That-Apply (RATA) sensory panel (n = 49) generated sensory profiles of 44 commercial white wines made from 7 different white grape varieties (Arinto, Fiano, Garganega, Greco, Verdejo, Verdelho and Vermentino), plus two benchmark examples each of an Australian Riesling, Pinot Gris and Chardonnay wine.
