Anthocyanins absorption must be affected by the composition
of the cell wall of yeasts and also to some extent on the yeast
strain. Yeast strains with low adsorption of anthocyanins will
remove less anthocyanins during fermentation. The selection of
the appropriate yeast strain is especially important to improve
color stability of red wines by means of producing different
amounts of metabolic precursors of pyranoanthocyanins and
through early formation of polymeric pigments during
fermentation
