why do we clink glasses before we toast?
The Real Answer
The exact origin of clinking glasses before a toast is not known. The popular story that people clinked hard enough to mix drinks and prove nobody had poisoned anyone is memorable, but credible historical support for it is lacking. Toasting itself is ancient; touching glasses is better treated as one of many later social rituals around sharing a drink rather than as a documented medieval poison test.
You raise a glass with people you trust, then knock all the glasses together because the toast feels unfinished without a tiny collision. The next time someone says it started as a poison test, that dramatic version is the one your brain will want to keep.

Clinking is automatic enough that the ritual becomes strange the moment you notice it. The poison story survives because it gives a dramatic explanation to a custom whose exact origin is much less tidy.
