Who really said it
Be careful to trust a person who does not like wine
Marx wrote no such sentence. Thanking a correspondent in Bordeaux for a gift of wine on 12 November 1866, he wrote that he inclined “somewhat to old Luther’s view that a man who does not love wine will never be good for anything” — and then added, in the same breath, “(There are exceptions to every rule.)” The letter survives in full ↗. The popular line swaps worthlessness for untrustworthiness, drops Luther, and drops the exception; Wikiquote lists it as misattributed ↗.
