The total monomeric anthocyanins content was also influenced by the grape dehydration process, and the CSV30, CSV40,MV30 and MV40 wines had lower levels of monomeric anthocyanins compared to control wines. Anthocyanins are responsible for the colour of the wines, and thus the colour index values for these samples also decreased. On the other hand, the content of polymeric anthocyanins was higher in wines elaborated with dried grapes, resulting in an increase in the colour tonality and density of the CSV30, MV30 and MV40 wines. The reaction between anthocyanins and flavanol or tannin compounds originates pigmented polymers that have an orange colour, resulting in an increase in the
