Required Amount of Matzah and Wine for the Seder: Difference between revisions

# If the cup holds more than a [[Revi'it]], one can fulfill one's obligation by only drinking one [[Revi'it]]. However, because some hold that one should drink the entire cup, if one plans on only drinking a [[Revi'it]] one should use a cup that only holds a [[Revi'it]]. Additionally, if a cup holds a number of Revi'iyot, many people can drink from the same cup as long as there is a [[Revi'it]] for each person. <ref>  

* Beit Yosef 472:9 quotes the Kol Bo and Orchot Chaim, who say that if a cup holds many Reviyot, one still has to drink only a Revi’it. The Ramban, however, argues that one must drink majority of the cup even if it is larger than a Revi’it. Although S”A 472:9 rules like the Kol Bo, if one doesn’t plan on drinking a lot, Mishna Brurah 472:33 advises having a cup that holds only a Revi’it in order to satisfy the opinion of the Ramban. </ref>

===How much must one drink===

# Preferably, one should drink a Revi’it of wine for each of the 4 cups of wine at [[the Seder]]. If this is difficult, one fulfills his obligation by drinking the majority of a Revi’it for each cup.<Ref> * The Gemara (Pesachim 108b) states that each of the 4 cups at the [[seder]] must contain a Revi’it of wine. Additionally, Rabbi Yitzchak (Pesachim 109a) says that a certain measuring cup in Tzipori held the volume of a Log and they would use it to measure the Revi’it for [[Pesach]]. Rashbam (109a s.v. U’vah) explains that each of the 4 cups had to hold a Revi’it of a Log and altogether that would equal a Log, the exact volume of the cup in Tzipori. Rambam (Chametz UMatzah 7:7), Tur, and S”A 472:9 codify this as halacha.
