Abstract:Leta 2010 smo preizkušali vpliv dodatka treh enoloških taninov na kakovost in kemijsko sestavo vina 'Modri pinot'. Pri kemijski sestavi vina se je vpliv dodatka taninov pokazal le pri merjenju vsebnosti skupnih fenolov. Pri meritvah taninov, antocianov in intenzitete barve razlik v primerjavi s kontrolo ni bilo. Pri senzorični analizi vina se je pokazal močan vpliv dodatka taninov. Na intenzivnost vonja je najbolj vplival tanin Structure, na kakovost vonja pa le največji odmerek dodanega tanina Superb, 6 g/hl. Vsi odmerki tanina Superb so izboljšali taninsko strukturo vina. Dodatek tanina Superb je izboljšal skupni vtis kakovosti vina pri najmanjšem in največjem odmerku, Finesse pa le pri srednjem (6 g/hl). Po primerjalni oceni po Buxbaum-u je razvidno, da so najboljše ocene kakovosti dobila vina z dodatkom tanina Superb.

Title:Impact of enological tanins on chemical composition and quality of 'Pinot noir' wine
Abstract:In the year 2010 the impact of three different enological tannins on chemical composition and wine quality of Pinot noir was tested. Considering the chemical composition of wine the addition of tannins resulted in higher content of total phenols only. As for the content of tannins or antocyanins and colour intensity no differences were observed. The tannin addition had a strong impact on the sensory evaluation of wines. Odour intensity was the strongest when adding the »Structure« tannin and odour quality was the highest when adding the biggest dose of the »Superb« tannin, the concentration being 6 g/hL. All the doses of the »Superb« tannin improved the tannin structure of wine. Better general impression of wine quality was acquired by either the highest or lowest addition of the »Superb« tannin and by moderate addition of the »Finesse« tannin (6 g/hL). The comparable sensory evaluation by the Buxbaum method showed the best quality of wines was obtained by the »Superb« tannin addition.
