Kiddush on Shabbos morning

Question:

I make kiddush for myself Shabbos morning before my husband is back from shul. However, I really would prefer not to eat mezonos food then.

1. Can I drink extra grape juice to fulfill kiddush (as during Pesach) and thereby not need to eat mezonos?
2. If so, how many ounces of grape juice would I need to drink?

Thank you so much for this invaluable site!

Answer:

1. It is preferable to eat something that is mezonos, however if it is hard for you to do so, you can drink drink extra grape juice. (As a side point, substituting a drink instead of mezonos can only be done with grape juice or wine, not with beer, whiskey, or any other drink.)
2. You would need to drink enough grape juice to be yotza kiddush, which is “maleh logmov”, (a cheekful, which depending on the size of the particular person is, but it is usually more than half a reviis) plus another reviis. Which in total would be  about 5-6 ounces.

Sources:

1. See M:B 273-25 that although the Geonim say that one may make kiddush and drink and extra reviis of wine, nevertheless since it is not agreed upon by all, therefore it should only be done when there is a need. Poskim.
2. M:B 273-27, Aruch Hashulchan 273-9, Shulchan Aruch Horav  273-9. we can rely on the measurement of R’ C. Naeh for this because, kiddush by day in m’drabonon, plus that fact that the Shulchan Aruch says that essentially only one full reviis is needed. We are going to do like the Mishna Berura etc. that it should be a maleh logmov plus a reviis, but for this we don’t have to be stringent and use the reviis of the Chazon Ish, and the smaller size reviis will suffice.
