Possibilities of producing grape-based alcoholic drinks from newly created grapevine varieties

Abstract

The paper is concerned with investigations on the possibility of producing grape-based alcoholic drinks from newly created grapevine varieties, such as Riesling Italian, Seedling 14660, Muscat Hamburg and Godominka. All chemical parameters for produced grape brandies, marc brandies and wine distillates complied with standards of quality as prescribed by the Regulations for quality of alcoholic drinks. Organoleptic evaluation proved that Seedling 14660 produced best scored wine distillate (17.85), Muscat Hamburg and Godominka gave best scored grape brandy (18.25) and Godominka yielded best scored marc brandy (18.40). Sensory properties of assessed brandies and wine distillate indicate that aroma and quality are gaining in intensity and level of improvement, starting from wine distillate to marc brandies. Also, intensive fruity-floral aroma reminding of lily-of-the-valley and iris fragrance is evident.

U radu su obavljena istraživanja vezana za mogućnost proizvodnje alkoholnih pića na bazi grožđa od nekih novostvorenih sorti vinove loze, i to: Rizling italijanski, Sejanac 1466, Muskat hamburg i Godominka. Kvantitativna hemijska analiza dobijenih lozovača, komovica i vinskih destilata pokazala je uklapanje svih parametara u norme kvaliteta, koje su predviđene i propisane Pravilnikom o kvalitetu i drugim zahtevima za alkoholnih pića, Sl.list SCG br.4/2003. Najbolje ocenjeni vinski destilat dao je sejanac 1466 (17,85), najbolju lozovaču sorte Muskat hamburg i Godominka (18,25), a najbolju komovicu sorta Godominka (18,40). Senzorne karakteristike ocenjenih rakija i vinskog destilata ukazuju na pojavu intenziviranja i oplemenjivanja mirisa i kvaliteta u smeru od vinskog destilata ka komovicama, kao i pojavu prisustva jednog intenzivnog voćno-cvetnog karaktera mirisa, koji je dosta podsećao na miris đurđevka i irisa.
