Bottle Cork BC-2 CAT# BC - 2. Bottle cork. Size: 1.2" X 1". .Since the Shabbat morning kiddush is rabbinically rather than biblically mandated, it has a lesser status than the Friday night kiddush. In order to elevate its importance, it is euphemistically referred to as "Kiddusha Rabba"—"The Great Kiddush." There are different versions for the kiddush on Sabbath morning, and it is generally shorter than the Friday night kiddush. Originally, this kiddush consisted only of the blessing over the wine.
