Jewish Festivals: Kiddush: Pour Revi'it

As on Shabbat, the minimum volume of kiddush beverage on which you may say Jewish festival kiddush (or havdala) is a revi'it:
  • 4 fl. oz. (119 ml) for d'oraita cases such as the first night of Jewish festivals (or Shabbat evening) kiddush, and
  • 3.3 fl. oz. (99 ml) for d'rabanan cases such Jewish festival lunch and evening/daytime meals on the second Jewish festival day (as well as kiddush for Shabbat lunch).
