Production of wine 'Istrian Malvasia' by sur lie technology

Sur lie tehnologija podrazumijeva odležavanje vina na finom talogu prvenstveno u drvenim, barrique, bačvicama, a u novije vrijeme odležavanje se može provoditi i u inox tankovima. U sklopu istraživanja praćeni su osnovni parametri kvalitete grožđa, mošta i vina. Grožđe je brano u trenutku tehnološke zrelosti. Istraživanje je provedene u dvije uzastopne godine, a cilj je bio prikazati različitost u tehnologiji proizvodnje između klasične proizvodnje u inox tankovima u odnosu na tehnologiju sur lie usporedbom fizikalno kemijskih parametara te hlapljivih spojeva. Temeljem dobivenih rezultata, može se zaključiti da su vina proizvedena sur lie tehnologijom imala naglašenije zlatno-žute nijanse uz kompleksniji aromatski profil te sveobuhvatni senzorni doživljaj.Sur lie technology involves aging wine on a fine lees primarily in wooden, barrique, barrels or noweday also in stainless steel tanks. As part of the research, the basic parameters of the quality of grapes, must and wine were monitored. The grapes were harvested at the moment of technological maturity. The research was conducted in tw oconsecutive years, and the aim was to show the difference in production technology between conventional production in stainless steel tanks compared to sur lie technology in terms of physicochemical parameters and the total content of volatile compounds. Based on the obtained results, it can be concluded that sur lie technology give wines with more intense golden-yellow shades with a more complex aromatic and organoleptic profile
