Overflowing the Havdalah cup

Hi,

There is a practice of filling the Havdalah cup to the point of slight overflow, for we are taught that a house will not have blessing in it if the residents do not spill their wine like water [meaning, if the hosts are miserly with their wine].

However, one should not spill too much, as that would be wasteful. [Spilling only a little is not "wasteful" since that teaches us a lesson in generosity.]

(Code of Jewish Law Orach Chaim 296:1; Mishneh Berurah 296:5)

Have a great day,
Mordechai
