Description
  • The objective was to follow losses in concentration of total anthocyanin pigments in red and rosé wines clarified with various doses of two commercial types of bentonite and to perform a sensory and analytical evaluation of differences in colour intensity of clarified and non-clarified wines. The loss of anthocyanins increased with the increasing doses of bentonite but statistically significant differences existed only between doses of 0.5 and 1.5 g/l. Not the type of bentonite but its dose showed an important effect on the extent of changes in colour intensity of wine. A sensory evaluation of colour intensity showed that in rosé and red wines doses of 0.5 g/l and 1.5 g/l, respectively,. reduced significantly intensity of wine colour as compared with non-clarified samples.
