Q. What should an elderly person do to be yotze with the four cups in the Pesach seder, if she can’t have any wine or even diluted grape juice?
A. Horav Shlomo Miller’s Shlit’a opinion is that in case of need one may drink four cups of common hot tea (not iced tea), since one may comply in need, using chamar medina, which is defined as a beverage worthy of being served to guests. It is also a beverage that one drinks simply to enjoy its taste, even when one is not thirsty. (Mishna Berura 472: 37; Igros Moshe, O. H. 2: 75).
Rabbi A. Bartfeld as advised by Horav Shlomo Miller Shlit’a.
