How much wine should be drunk for kiddush friday night, kiddush day and havdallah to be yozei? Can you tell me in ounces, minimum and lechathillah? What amount should be drunk in ounces obligates al hagefen after havdallah or general?
Answer:
The amount that must be drunk is melo lugmav, which means a “cheekful.” This is an individual amount, and can be measured by halving the amount that fits into one’s mouth.
The average amount is the majority of a revi’is, which is approximately 40cc (according to the more lenient amount).
Th amount that needs to be drunk for a berachah acharonah is a revi’is, which is 86cc, or 2.9 fluid ounces (the smaller amount of Rav Chaim No’eh).
