Abstract

Napravljen je sustavan pregled osnovnih fizikalno-kemijskih parametara crnog vina Merlot (berba 2015.) različitih proizvođača iz Republike Hrvatske. Ukupno je analizirano 138 uzoraka vina u prometu sa zaštićenom oznakom izvornosti (ZOI), od kojih je 84 dodatno označeno tradicionalnim izrazom „kvalitetno vino kontroliranog zemljopisnog podrijetla (KZP)“, dok je 54 uzorka dodatno označeno tradicionalnim izrazom „vrhunsko vino kontroliranog zemljopisnog podrijetla (KZP)“. U svakom uzorku su analizirani sljedeći parametri: relativna gustoća 20/20 °C, stvarni alkohol, ukupni suhi ekstrakt, reducirajući šećeri, ukupna kiselost, hlapiva kiselost, pH vrijednost, pepeo, slobodni i ukupni sumporni dioksid. Rezultati pokazuju da vina Merlot, iako su proizvedena od iste sorte grožđa, razlikuju se u pojedinim analiziranim parametrima, jer potječu iz područja Republike Hrvatske koja imaju različite klimatske i zemljopisne, ali i geološko/pedološke značajke.

Abstract (english)

A systematic review of the basic physico-chemical parameters of red wine Merlot (vintage 2015) from various producers from the Republic of Croatia was made. A total of 138 wine samples on the market with protected designation of origin (PDO) were analyzed, of which 84 were additionally marked with the traditional term "quality wine with controlled designation of origin ", while 54 samples were additionally marked with the traditional term "premium quality wine with controlled designation of origin". In each sample, the following parameters were analyzed: relative density 20/20 °C, alcohol, total dry extract, reducing sugars, total acidity, volatile acidity, pH value, ash, free and total sulfur dioxide. The results show that Merlot wines, although produced from the same grape variety, have differences in some analyzed parameters because they originate from the territories of the Republic of Croatia which have different climatic and geographical, but also geological/pedological characteristics.
