In the 19th century people used to put strawberries in their glasses of claret to temper the heating effect of the wine. A city Alderman, having drunk deep, blamed his hangover not on the 6 bottles of claret that he had imbibed but on that “confounded single strawberry” that he had kept all night in the bottom of his glass!
In reality farmers used to spread manure around the strawberry plants during those days - which was not very hygienic. So people put strawberries into red wine to be able to eat them without any problems. Interesting, isn’t it?
