Hilchot Shabbat 29:16-17 (Grape Juice, Beer, Raisin Wine for Kiddush: Yes or No?)
9:23 am
Can a person make Kiddush over a cup of wine from which someone already tasted, assuming that there is still more than the minimum amount? Can a person use grape juice? Beer? Raisin wine? Do the same rules apply to Havdalah?
