* On the statement of Rav Nachman (Pesachim 108b) that one fulfills his obligation by drinking a majority of the cup, Tosfot (s.v. Ruba) comments that preferably, one should drink an entire Revi’it. The Bach (472 s.v. Mah SheKatav VeEin) writes that it is obvious that one should only rely on the concept of majority being considering like the entirety (Rubo K’kulo) after the fact, however, l’chatchila one should drink an entire Revi’it. | * On the statement of Rav Nachman (Pesachim 108b) that one fulfills his obligation by drinking a majority of the cup, Tosfot (s.v.

* 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> | * 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 precise measurement of a [[Revi'it]] is a matter of dispute; several opinions are outlined below:<ref>Background: The Gemara (Pesachim 109a) explains that a Revi’it is the volume of 2x2x2.7 fingerbreadths. Additionally, the Rashbam (ibid. s.v. DeHaynu) writes that the Revi’it is equal to 1.5 times the volume of an egg. Because of the apparent discrepancy between these two measurements, the Tzlach (Pesachim 116b) concluded that the egg of the days of the Gemara was twice the size of the modern-day egg. The Mishna Brurah 486:1 concludes that for the 4 cups of wine at the Seder, which are only d’rabanan, one need not follow the Tzlach’s strict view. </ref> | # The precise measurement of a [[Revi'it]] is a matter of dispute; several opinions are outlined below:<ref>Background: The Gemara (Pesachim 109a) explains that a Revi’it is the volume of 2x2x2.7 fingerbreadths.

## Rabbi Mordechai Willig (“The Shiurim of Seder Night” min 1-10, and Pesach To-Go 5771 p. 60) holds that the size of an egg with its shell is 50 cc, | ## Rabbi Mordechai Willig holds that a Revi’it is 2.5 fl oz (75cc). <ref> Rabbi Mordechai Willig (“The Shiurim of Seder Night” min 1-10, and Pesach To-Go 5771 p. 60) holds that strictly speaking the size of an egg with its shell is 50 cc, and the [[Revi'it]] is 1.5 eggs with its shell, resulting in a Revi'it of 2.54 fl oz. </ref> | ||
## Rav Ovadia Yosef | ## Rav Ovadia Yosef writes that a Revi’it is 2.7 fl oz (81cc). <ref>Rav Ovadia Yosef (Chazon Ovadia p. 16) writes that the Revi'it is 81cc. This is based on the measurements of Rav Chaim Noeh (Shiurei Tzion p. 69) with slight adjustments. </ref> | ||
## The Laws of [[Pesach]] | ## Rabbi Avraham Blumenkrantz writes that a Revi’it is 2.9 fl oz (86cc). <ref>Rabbi Avraham Blumenkrantz (The Laws of [[Pesach]] 5771 pg 111) writes that since the four cups are Derabbanan one may use a cup that holds 2.9 oz. <ref> | ||
## Rabbi Shimon Eider (Halachos of Pesach p. 229) writes that according to his measurements, the Revi’it is 3 fl oz. <ref>Halachos of [[Pesach]] (Rabbi Shimon Eider, Chapter 20, Sec D 5, pg 228-230) writes that since the four cups are Derabbanan one may have the smaller measurement which is measuring by eggs and not by thumbs and according to his calculation a Reviyit should be 3 oz and if one is unable to have a Reviyit one fulfills one's obligation with a majority of a Reviyit. See also Weekly Halacha (by Rabbi Neustadt, http://www.torah.org/advanced/weekly-halacha/5760/tazria.html) who writes that one may rely on the view of Rav Chaim Noeh who holds that 3 oz is sufficient being that the cups of wine are Derabbanan. </ref> | ## Rabbi Shimon Eider (Halachos of Pesach p. 229) writes that according to his measurements, the Revi’it is 3.0 fl oz. <ref>Halachos of [[Pesach]] (Rabbi Shimon Eider, Chapter 20, Sec D 5, pg 228-230) writes that since the four cups are Derabbanan one may have the smaller measurement which is measuring by eggs and not by thumbs and according to his calculation a Reviyit should be 3 oz and if one is unable to have a Reviyit one fulfills one's obligation with a majority of a Reviyit.

## Rabbi Dovid Feinstein (Kol Dodi Haggadah, 5730, p. 4) writes that based on measuring large eggs a Revi’it is fl 3.3 oz. <ref>In the 5745 edition, however, he says that the Revi’it is fl 2.9 oz. See also Rabbi Yisroel Bodner (Halachos of K’zayis p. 24 n. 24) who writes that he spoke to Rav Dovid Feinstein about how he arrived at his measurements and was told that his father, Rav Moshe Feinstein, didn't measure it himself but rather a student measured 'large' eggs and came up with 2.2 fl oz per egg. Rav Dovid added, if he, Rav Bodner, arrived at a smaller measure with his own measurements he should follow that. Rav Bodner writes that according to his measurements the average egg was 55cc (1.92 fl oz). Nonetheless, in terms of Bracha Achrona Rav Bodner (p. 26) follows the measurements of Rav Chaim Noeh who measured the average egg to be 57cc. </ref> | ## Rabbi Dovid Feinstein (Kol Dodi Haggadah, 5730, p. 4) writes that based on measuring large eggs a Revi’it is fl 3.3 oz. <ref>In the 5745 edition, however, he says that the Revi’it is fl 2.9 oz.
