Ata Chonantanu after havdala

Question

Should one say ata chonantanu if they have already heard havdala at home?

I don't know that there is a problem with it necessarily (it is not its own bracha, which is the point after all) but should it be said?

Answer 1

The Talmud asks this question on Brachot 33a and concludes that one still says Attah Chonantanu in Shemone Esrei even if he already recited Havdala on a cup of wine, because the Havdalah in Shemone Esrei was the original and therefore primary form of Havdala enacted. This ruling is brought in the Tur OC 294 and cited in the Mishnah Berurah there :1.
