Is eating one whole olive considered as a kezayit (for the purposes of a bracha acharona)? Or is the pit, which most people do not eat, not considered - making only the remainder of the olive (which of course is less than a kezayit) count towards the shiur?

    I assume you aren't looking for answers that say modern olives are not the same size as olives were a few thousand years ago – Double AA Mar 11 '18 at 13:08

    ...who eats the pit? – bondonk Mar 11 '18 at 13:40

    Note that this might present other issues of eating an entire 'beriya', a complete object, which even if less than a kezayis, is discussed in the poskim as possibly needing a Bracha Achrona. – Salmononius2 Mar 11 '18 at 18:55

    @Salmononius2 The Rema rules that without the pit it would not be considered a beriya. – Alex Mar 11 '18 at 20:33

The Talmud explicitly addresses this.

Berachos 38b-39a

אמר ליה רבי ירמיה לרבי זירא רבי יוחנן היכי מברך על זית מליח כיון דשקילא לגרעיניה בצר בצר ליה שיעורא אמר ליה מי סברת כזית גדול בעינן כזית בינוני בעינן (והא איכא) וההוא דאייתו לקמיה דרבי יוחנן זית גדול הוה דאע"ג דשקלוה לגרעינותיה פש ליה שיעורא דתנן זית שאמרו לא קטן ולא גדול אלא בינוני וזהו אגורי ואמר רבי אבהו לא אגורי שמו אלא אברוטי שמו ואמרי לה סמרוסי שמו ולמה נקרא שמו אגורי ששמנו אגור בתוכו

R. Jeremiah asked R. Zera: How could R. Johanan make a blessing over a salted olive? Since the stone had been removed, it was less than the minimum size! — He replied: Do you think the size we require is that of a large olive? We require only that of a medium sized olive, and that was there, for the one they set before R. Johanan was a large one, so that even when its stone had been removed it was still of the requisite size. For so we have learnt: The ‘olive’ spoken of means neither a small nor a large one, but a medium one. This is the kind which is called aguri. R. Abbahu, however, said: Its name is not aguri but abruti, or, according to others, samrusi. And why is it called aguri? Because its oil is collected [agur] within it. (Soncino translation)

In other words the size of a kezayis is the size of a medium olive including the pit. Therefore, eating a medium olive without the pit would not be considered eating a kezayis, but eating a large olive without the pit would be considered eating a kezayis.



If we understand a kezayit to be the volume of an olive (rather than a complex measure per R' Chaim Naeh et al.), then a single olive is not a kezayit, as the pit is considered within this volume.

In this case, a kezayit would be about one and one half olives, excluding their pits.

As always, CYLOR
