To fulfill the two requirements for Shabbat evening kiddush:

1. Say, or hear, the Shabbat evening kiddush blessings/segments:
   • Borei pri ha'gafen (on wine or grape juice only), OR
     Ha'motzi (on two challot if you have no wine or grape juice, as chamar medina is not permitted for Shabbat evening kiddush. See Challot for Evening Kiddush) AND
   • Mekadeish HaShabbat.
2. Establish a halachic “meal” (kovei'a se'uda) by either:
   • Drinking 4 fl. oz. (119 ml) of wine (or grape juice) within 30 seconds, OR
   • Eating at least 1.9 fl. oz. (56 ml) of bread or mezonot of any type (within 4 minutes) shortly after saying or hearing kiddush.

You must say the blessing on wine if you:

• Heard kiddush, then
• Spoke, and
• Now want to drink some wine, even from the cup over which kiddush was made.

Ideally, fill your kiddush cup to just above the rim, even if the cup is larger than 4 fl. oz. (119 ml). Don't make the cup overflow.

As on Jewish festivals, any adult Jew, male or female, may say kiddush for him/herself and also include any other Jews of any age or gender.

See Eating from Start of Shabbat until Kiddush.
 

As on Shabbat, once you have said the amida of Jewish festival shacharit, you may not eat any food until you have said (or heard) kiddush and finished kiddush requirements by either drinking 4 fl. oz. (119 ml) of wine/grape juice or eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of mezonot or bread.

As on Shabbat, you may eat non-mezonot and non-bread food before praying Jewish festival shacharit and without making kiddush, in order to avoid hunger or hypoglycemia (low blood sugar).

You may drink your own beverage as long as:

• The leader (mevareich) has said Jewish festival (or Shabbat) kiddush for other people, and
• At least 2 fl. oz. (59 ml) of the wine (or other appropriate beverage) over which kiddush was made has been drunk.

You may speak, even without having drunk anything yourself, once:

• The leader (mevareich) has said Jewish festival (or Shabbat) kiddush for other people, and
• At least 2 fl. oz. (59 ml) of the wine (or other appropriate beverage) over which kiddush was made has been drunk.

Any adult Jew, male or female, may say kiddush for him/herself and, as long as he/she still needs to say kiddush for him/herself, may include any other Jews of any age or gender.
Any Jewish male, 13 years old or older, may say kiddush for anyone else, either gender and any age, even if he has already fulfilled his personal requirement of saying kiddush.
Any Jewish female, 12 years old or older, may say kiddush for any other females but not for men, except that on the 2 Passover seder nights, a Jewish female who is at least 12 years old may even say kiddush for men, if the men are not able to say it for themselves. (Women may also say kiddush for men on Shabbat evening).
Reason Any person who is obligated to fulfill the mitzva of kiddush may say it for another person.  It is questionable whether women are obligated to say (or have said for them) Jewish festival morning kiddush.
 

For women's minimum obligation to pray before saying Shabbat morning kiddush and eating, see Women and Minimum Prayer before Saying Shabbat Kiddush.

For women and minimum prayer before eating prior to Jewish festival kiddush, see Women and Minimum Prayer before Jewish Festival Kiddush.
 

Wine (or grape juice) is the only drink permissible for Friday evening (or Jewish festival evening) kiddush. If you do not have wine or grape juice with which to make evening kiddush, see Challot for Evening Kiddush.

 Once Shabbat begins for you—either at sunset or before (such as if you lit Shabbat candles)--you may not eat or drink before hearing kiddush. 

Once the leader (mevareich) has said kiddush for other people and someone has drunk at least 2 fl. oz. (59 ml) of wine (or other appropriate beverage) over which kiddush was made, you may:

• Speak, even without having drunk anything yourself.
• Drink.
• Eat.
