Coca-Cola’s secret formula is just that – a secret. The secret was revealed to Rabbi Tobias Geffen over 70 years ago, in order for the soft drink to receive kosher certification.
Rabbi Tobias Geffen lived for 100 years: He was born in 1870 and died in 1970. For 60 odd years of his life he lived in Atlanta, Georgia, the hometown of the Coca-Cola Company. Geffen published a handful of books and was considered an important halakhic arbiter, but more than anything else he is identified with a responsum he issued in 1935 − stating that Coca-Cola is kosher and can also be drunk during Passover.
