7. The Zeman by beverages – In how much time must the Revius be consumed?[1]

Some Poskim[2] rule that the Revius amount must be drunk within the time it [normally] takes a person to drink a Revius, in order to say the after blessing. Thus, if one quickly drank a half of the Revius in a faster pace than most people, and then after a slight delay finished drinking [the remainder of the Revius], then if from the start of the drinking until the completion [of the drinking of the Revius] the amount of time it takes a normal person to drink a Revius did not yet pass, then the two gulps join each other to obligate an after blessing. If, however, it took more than this amount of time to drink the Revius, then the two gulps do not join each other and an after blessing is not recited. (Furthermore, even if one did not stop for even a moment from drinking the Revius, although he drank it very slowly in a way that it took him more time that a normal person who drinks a Revius, then an after blessing is not said.[3]) [According to this opinion, an after blessing is never recited after drinking a hot beverage such as tea and coffee, being that it takes more than a Revius timespan to drink a Revius of the hot beverage.] However, other Poskim[4] rule that the Revius amount can be drunk within the time it takes a person to eat a Pras of bread [i.e. Kdei Achilas Peras, which is between 3-4 minutes[5]] just as we rule regarding foods. Practically, the main opinion follows the second, latter opinion, [and hence so long as a Revius of the beverage was consumed with 3-4 minutes an after blessing is recited].[6] Thus, an after blessing is recited after drinking a hot beverage such as tea and coffee even if drunk slowly, so long as a Revius of the liquid was drunk within Kdei Achilas Peras. [To note however that many Sephardim have the custom to not recite an after blessing after drinking tea and coffee as rules the first opinion above.]

[6] Admur Seder ibid [unlike Luach ibid]; See also Admur 612:15 where he rules like the 2^nd opinion; See Sheiris Yehuda 15 that Admur told him that here he decided to be lenient being that by a Shiur Revius its possible even the Rambam agrees that we measure by Kdei Achilas Peras, and his dispute is only in a case of Malei Lugmav, such as Yom Kippur and the night of the Seder; Ketzos Hashulchan 59:5

Other opinions in Admur and Poskim: See Admur Luach ibid who concludes “Safek Brachos Lihakel” [to require Shiur Revius of Zeman]; Likewise see Admur 472:20 regarding the four cups of wine who concludes to initially be stringent like the 1^st opinion and so rule all the following Poskim that the shiur by a Revius is Kdei Shetiyas Revius: M”A 472:11; Peri Chadash 472; Elya Raba 472:15; Chok Yosef 472:13; Derech Hachaim 472:9; Chayeh Adam Haseder 3; M”B 472:34; Kaf Hachaim 472:68

The law by wine: Some Poskim rule that regarding wine, one must consume a Kezayis of the wine within Kdei Shetiyas Revius, even if he consumes a total of a Revius with Kdei Achilas Peras. [Ketzos Hashulchan 59 footnote 9] Other Poskim, however, dispute this ruling. [See Rav Alyashvili footnote 50]
