| | By the sixth century BC, Greeks had discovered that poisoning wine was an excellent way to get rid of their enemies, and so to reassure guests at a social function, it became necessary for the host to take the first drink. The Romans added a piece of burnt bread, or �tostus,� to the custom because it absorbed acid, making the wine more pleasant to drink. Flattering words were spoken during the toasting ceremony to reassure the guests of their safety. |
