The cover picture shows the bathochromism observed when the grape‐derived wine red pigment oenin reacts with the oak‐derived C ‐glycosidic ellagitannin vescalagin to furnish the deep‐purple anthocyano‐ellagitannin 1‐deoxyvescalagin‐(1β→8)‐oenin. Results of a detailed physicochemical characterization of this fascinating new hybrid pigment are discussed in the article by O. Dangles S. Quideau, et al. on p. 55 ff. Such a bathochromism‐inducing covalent association is a plausible consequence of the aging of wine in oak‐made barrels. Cheers!
