How much must one drink for kiddush?

Hi,

To fulfill the Mitzvah of Kiddush, one must drink a cheekful. The standard measure for a “cheekful” is that it is the majority of a “Revi'it.” A Revi'it is about 3.8 ounces, making a cheekful approximately 2 ounces.

One whose frame is so large that his “cheekful” is significantly larger than 2 ounces should drink whatever amount is a cheekful for him.

(Code of Jewish Law Orach Chaim 271:13; Mishneh Berurah 271:68)

Have a great day,
Mordechai
