How much is the Melo Lugmav that one must drink for Kiddush? If I (the person who makes Kiddush) does not want to drink a full Melo Lugmav, can I just drink a drop of wine, and have my wife drink the Melo Lugmav?

ב"ה Shalom, The Shulchan Aruch (Orach Chaim271: 13) defines the measure of Melo Lugmav as the amount of liquid one can fill in one cheek, which is the most of a a Revi'it. In most people, some place it between 50-55 ml (פסקי תשובות סי' רעא:לג) and some place it between 35-42 ml. (מקראי קודש דיני יום כיפור פרק ו) To begin with the person who makes Kiddush should drink the Melo Logmav. However, if you cannot drink the full amount of Melo Lugmav, you should take a taste of the wine and your wife should drink the Melo Lugmav.
