Passing the kiddush cup around

Hi,

There is a widespread practice of having the host pass around the Kiddush cup, or at least add to the individual cups from the Kiddush cup. This is a nice practice. In fact, though, this is not obligatory; each guest may have his/her own cup with some appropriate beverage in it, and may drink from it without any addition of the Kiddush beverage.

The only time the host need add is if someone has already partaken from one of the guest-cups, so that this cup is rendered flawed. Adding some of the Kiddush beverage corrects that flaw. Otherwise, though, there is no need to add from the Kiddush cup.

Have a great day,
Mordechai
