“…Use of enzymes support the extraction, maximize juice yield, facilitate filtration and intensify the wine flavour and colour. The short vatting with the addition of pectolytic enzymes increases wine colour intensity, but the concentration of extracted tannins remains low what results with wines that taste less astringent (Zoecklein et al 1995;Pardo et al 1999;Bautista-Ortín et al 2007;Romero-Cascales et al 2008;Mojsov et al 2010;Río Segade et al 2015). According to the study of Romero-Cascales et al (2008) enzymes accelerate the extraction of phenolic compounds from grape skin but, if maceration period is too long the control wine can reach similar values of colour intensity.…”

“…The dominant forms were those of 3-O-glucosides. Of these, malvidin is the most common pigment in Vitis vinifera varieties as well as the most stabile form of anthocyanins (Zoecklein et al 1995;Río Segade et al 2015;González-Neves et al 2016). In wine produced without enzyme addition the share of 3-O-glucosides was 84% of total detected anthocyanins (95.60 mg/L), while in wines produced by the addition of enzymes it was 79% for Vinozym Vintage wine and 69% for Sihazym Extro, respectively.…”

Crljenak kaštelanski or Tribidrag is a Croatian autochthonous grape variety which is a parent of the America's most popular variety Zinfandel or Italian Primitivo. The aim of this study was to investigate the dynamics of extraction of phenolics and changes in antioxidant activity of the samples collected during maceration of C. kaštelanski grapes processed using two different macerating enzymes. According to the obtained results it can be concluded that wines from C. kaštelanski grapes are great source of bioactive phenolics although differences in phenolic profiles between control and enzyme-treated wines were detected. The highest content of total phenolics was detected in control wine (2691 mg GAE/L). Use of pectolitic enzyme Vinozym Vintage improved anthocyanin extraction, while higher colour parameters were observed for wine samples produced using Sihazym Extro. The statistical analysis confirmed great influence of total phenolics and concentrations of some individual phenolic compounds (e.g. catechin, gallic acid, epicatechin) on reducing and free radical scavenging activity of wine samples while the impact of anthocyanins was not detected. According to the obtained results it can be concluded that use of enzymes has slightly negative effect on total phenolics and wine antioxidant properties, but it increases the extraction yield of wine colour components what enables shorter maceration and prevents colour losses during the aging process.

“…Ampelographic descriptions of Kratošija accessions [27]. Out of the six remaining samples, three accessions were found to be misnomers, one coincides with a previously identified variety in another country, and two accessions showed the original SSR profile which did not match any of the known varieties [37]. Accession of Japudžak from Montenegro is identical to the Turkish variety Yapıncak [38].…”

Montenegro is a small country in Balkan Peninsula with very long tradition of grapevine growing and wine making that originate from the pre-Roman period. Dominant place in Montenegrin viticulture belongs to autochthonous grapevine varieties Vranac, Kratosija, and Krstac, while in minor part, the other varieties are presented. Among many literature sources, the oldest historical document that pointed out the importance of autochthonous varieties is The Medieval Statute of Budva from fifteenth century. In order to better present Montenegrin germplasm, this research provides an overview of literature, ampelographic, and genetic analysis on autochthonous and domesticated varieties. Achieved results showed an important breeding history of grapevine and a large number of unique DNA profiles. Montenegro has the richness of grapevine diversity that can significantly enrich the diversity of vines in Europe.

“…Conservation of grapevine genetic resources in Croatia started about 25 years ago and six germplasm collections were established [56]. Biodiversity of Croatian grapevine germplasm has been investigated by SSRs, to a certain extent, in terms of genetic identification and variability and clarification of synonyms and homonyms [36,[57][58][59][60][61], genetic similarity to other germplasm [62], partial reconstruction of chlorotypes [53] and parentage reconstruction [63][64][65], and also partially indirectly as part of worlds' largest collections [14,15].…”

Croatian viticulture was most extensive at the beginning of the 20th century, when about 400 varieties were in use. Autochthonous varieties are the result of spontaneous hybridization from the pre-phylloxera era and are still cultivated today on about 35 % of vineyard area, while some exist only in repositories. We present what is the most comprehensive genetic analysis of all major Croatian national repositories, with a large number of microsatellite, or simple sequence repeat (SSR) markers, and it is also the first study to apply single nucleotide polymorphism (SNP) markers. After 212 accessions were fingerprinted, 95 were classified as unique to Croatian germplasm. Genetic diversity of Croatian germplasm is rather high considering its size. SNP markers proved useful for fingerprinting but less informative and practical than SSRs. Analysis of the genetic structure showed that Croatian germplasm is predominantly part of the Balkan grape gene pool. A high number of admixed varieties and synonyms is a consequence of complex pedigrees and migrations. Parentage analysis confirmed 24 full parentages, as well as 113 half-kinships. Unexpectedly, several key genitors could not be detected within the present Croatian germplasm. The low number of reconstructed parentages (19%) points to severe genetic erosion and stresses the importance of germplasm repositories.
