I understand that ideally red wine should generally be used for kiddush. On Pesach, I have heard that one should go to great lengths to drink wine (rather than grape juice) for the four cups at the seder. On the other hand, many families use grape juice lechatchila for regular shabbos kiddush throughout the year.
Of course, for kiddush levana we obviously prefer white wine. But what about grape juice? Is it permitted to use white grape juice for kiddush levana? Could we possibly even be yotzei with red grape juice?
