Bottle Cork BC-5 CAT# BC - 5. Bottle cork. Size: 1.2" X 1". .* Some Hasidic and Sephardic Jews dilute the wine with water before kiddush on Friday night to commemorate the old custom of "mixing of the wine" in the days when wine was too strong to be drunk without dilution. * Some Jews make kiddush on Shabbat morning over liquor instead of wine. When this is done, the blessing recited is she-hakol nihyeh bid'varo instead of borei p'ri ha-gafen. The Mishnah Berurah (an authoritative Ashkenazi halakhic text) allows liquor to be substituted for wine on the grounds that it is Hamar Medina, generally interpreted to mean a drink one would serve to a respected guest. Most people consider non-wine alcoholic beverages to be Hamar Medina, but there is some disagreement on the status of soft drinks and other non-alcoholic beverages. There is also a question as to whether kiddush requires a revi'it when recited over hard liquor when the typical serving is less than a revi'it.
