Required Amount of Matzah and Wine for the Seder

From Halachipedia

The four cups of wine

  1. The cup of wine must be filled with a Reviyat of wine and one must drink a full Reviyat or majority. [1]
  2. If the cup holds a lot of Reviyot, many people can drink from it, only as many people as there are Reviyot in the cup. [2]

Within how long must one drink the wine

  1. Lechatchila, one should drink the majority of the Reviyat Bevat Echat, at one time (without any interruption). [3]
  2. Bedieved, one must drink the cup within the time of a Kdei Achilat Pras to fulfill the obligation, otherwise one must repeat drinking the wine. [4]
  3. Thus, one shouldn't take a cup that has a thin spout because one won't be able drink the whole cup at once. [5]

Types of wine

  1. If one hates wine or if it gives him a headache (but not if it's going to make him sick in bed) he should try to have the wine to fulfill the mitzvah of the four cups of wine. [6]

  2. The Orchot Chaim and Kolbo hold that as many people as there are Reviyot can drink from the cup and fulfill their obligation. However, Ramban holds that if the cup holds many Reviyot, one person needs to drink majority of the cup and taken split it up with others. S"A 472:9 rules like the Orchot Chaim and Kolbo.

  4. Rama 472:9 in name of the Rokach quoted by the Bet Yosef writes that one shouldn't drink with a large pause. Magan Avraham 472:11 explains that the long pause is a Kdei Achilat Pras. Mishna Brurah 472:34 rules like the Magan Avraham and adds that even though the Ashkenazi practice is not to repeat to drink the third and forth cup if one forgot to lean because it may look like one is adding a cup to the established cups, even so here one should repeat because one has not fulfilled his obligation according to anyone.
  5. Rama 429:15
  6. S"A 472:10 says that even if one hates wine or it is harmful to his health one should push himself to have the wine to fulfill the mitzvah. Mishna Brurah 472:35 explains that it gives one a headache but not that it makes one sick in bed.
