סימן עז סעיף יג
גַּם בַּיּוֹם בִּסְעוּדַּת שַׁחֲרִית צָרִיךְ לְקַדֵּשׁ עַל הַכּוֹס, דְּהַיְנוּ שֶׁמְבָרֵךְ עָלָיו בּוֹרֵא פְּרִי הַגָּפֶן, וְזֶהוּ הַקִּדּוּשׁ. וְגַם נָשִׁים חַיָּבוֹת בְּקִדּוּשׁ זֶה (פרמ"ג). וְגַם קֹדֶם קִדּוּשׁ זֶה, אָסוּר לִטְעֹם כְּלוּם, וַאֲפִלּוּ מַיִם, כְּמוֹ בְּקִדּוּשׁ הַלַּיְלָה (וְעַיֵּן לְעֵיל סִימָן ח' סָעִיף ב') וּמִצְוָה מִן הַמֻּבְחָר שֶׁיִּהְיֶה קִדּוּשׁ זֶה גַּם כֵּן עַל הַיַּיִן דַּוְקָא. וְאִם חָבִיב לוֹ יַיִן שָׂרָף וּמְקַדֵּשׁ עָלָיו, גַּם כֵּן יוֹצֵא, אַךְ שֶׁיְהֵא הַכּוֹס מַחֲזִיק רְבִיעִית, וְיִשְׁתֶּה מְלֹא לֻגְמָיו בְּלִֹי הֶפְסֵק וְאִם מְקַדֵּשׁ עַל הַיַּיִן וְרוֹצֶה לִשְׁתּוֹת גַּם יַיִן שָׂרָף אוֹ קַאפֶע, (עַיֵּן לְעֵיל סִימָן מ"ט סָעִיף ו').
By day, at the morning meal, you must also recite kiddush over a cup [of wine]. You need say over it only the berachah Borei peri hagafen [Who creates the fruit of the vine] and this is [sufficient for] kiddush. Women are also obligated to say this kiddush. Before this kiddush it is also forbidden to taste any food or even water,48It is, however, permitted to drink water in the morning before Shacharis because you are not yet obligated to say kiddush. A sick person who is permitted to eat and drink before praying should certainly recite the kiddush before eating [Biur Halachah 281]. just as before the kiddush at night.49If you have nothing over which to recite kiddush at night but you expect that it will arrive at night, you should wait until midnight (Chayei Adam, Mishnah Berurah), but for the morning kiddush you need not wait [Mishnah Berurah 289: 10]. It is a mitzvah performed in its perfection when this kiddush is also said specifically over wine. [However], if you prefer whiskey and say kiddush over it, you also fulfill the mitzvah,50Chayei Adam, Mishnah Berurah rule that it is even permitted initially, provided that whiskey is drunk daily by most people. See Magein Avraham 272. but you should be careful [to see] that the cup holds a revi'is51See glossary. and you should drink a full cheek without interruption.52Magein Avraham 194: 4. See Chasam Sofer Resp. 49 and Maharsham (Vol. 1, Resp. 175). If you say kiddush on wine and you also want to drink whiskey or coffee see chapter 49, paragraph 6, regarding the proper berachah.
