Boreh Nefashot, the after-bracha (blessing) for all foods not covered by Hamotzi and Me'en Shalosh, is tricky, because it covers the things one might partake of often.

Example, someone has a drink on their desk. They drink a revi'it (a measure of volume) in the prescribed time and way to qualify the requirement to say Boreh Nefashot. They are very likely to sip more within the shiur of time (generally 90 minutes, according to e.g. Yalkut Yosef), or make a coffee, or snack on something. Yet they might not.

The gravity of missing a bracha is unfathomable, yet so is the gravity of saying a bracha l'vatala (wastefully).

What advice have you seen to deal with when to draw the line and say Boreh Nefashot?

EDIT: Question voted for close because it is a duplicate of this: What b'rachot do you say (and when) if you drink intermittently all day?

Please could anyone who has answered copy/paste your answer there.

    Vezos haberacha as a matter of good advice says once you're chayav in a borei nefashos, even though you plan to sip water over the next period of time, to say borei nefashos first and then a new shehakol on the water you'll be sipping. This is so you don't forget to say it after your water sipping, so it's not levatala.

    Some argue borei nefashot is optional (at least in many cases) so it might not be as big a deal as you say.

  • @DoubleAA Interesting. That would potentially be a counterforce against the reasoning behind the advice of Vezot haberacha

My answer is phrased so that it is readable to those less familiar with some of the concepts surrounding berachot, so forgive me for stating some 'basic stuff' for you as if they are new information. I don't mean to be impertinent.

The gravity of missing a bracha is unfathomable, yet so is the gravity of saying a bracha l'vatala (wastefully).

It is not entirely true that missing a berach is unfathomable, because as "safek brachot l'hakel" (doubtful blessings are treated leniently) (ספק ברכות להקל). Yes, we shouldn't miss berachot, but making a beracha l'vatala is generally considered just a smidgen worse than missing one. See for example Shulchan Aruch OC 210:2 and Shulchan Aruch OC 18:1

I think you are close to answering your own question in regards to your reference to the shiur of time.

An example of some disagreement in the Mishna Berurah 210:19:

(יט) וספק ברכות להקל - היינו באפילו אם הוא בולע לא יברך כיון שאין כונתו לאכילה וכסברא הראשונה. והנה המ"א חולק על השו"ע והרמ"א וס"ל דבבולע לכו"ע חייב לברך אבל כמה אחרונים החליטו עם פסק הרמ"א דהוא ספק ברכה ולא יברך ולכתחלה טוב ליזהר הרוצה לבלוע שיתכוין ליהנות ממנו בתורת אכילה ויברך עליו [ח"א]:


"And doubtful blessings are treated leniently, meaning that even if he swallowed it, he should not recite a blessing since his intention is not to eat and according to the first opinion. And here, the Magen Avraham disagrees with the Shulchan Aruch, and the Rema and holds that if he swallowed it, he is obligated to recite a blessing, but many later authorities have decided with the ruling of the Rema that it is doubtful blessing and he should not recite a blessing. Initially, it is good to be careful, the one who wants to swallow, should intend to enjoy it according to the laws of eating and recite a blessing on it"

So generally, I extrapolate from the many applications of safek beracha lehakel that if you are uncertain whether or not you should recite a blessing, you should not recite it, as long as you stay within the alloted shiur. If you drink a glass of orange juice large enough to warrant boree nefashot, but you are unsure whether you might drink more, then safek berachot lehakel would mean that you rather postpone saying boree nefashot than saying it multiple times within the shiur.

    This might also depend on how much one trust oneself to say the final bracha or forget. Someone who forgets regularly might be better saying b.n. every time he drinks (and I have seen distinguished rabbanim do this)

    @mbloch Vezot Habracha quoted by robev indicates so. This answer is great, and sounds like the opinions quoted would be very against R' Mandelbaum eitza. Trying to get to the bottom of all this.

I discussed your interesting question with R Ari Wasserman, author of many sefarim.

He recommended making the after-bracha once finished with the item at hand (e.g., cup of coffee or water). The possibility that one may (or may not) drink more an hour later doesn't make this a bracha l'vatala (I think you meant bracha she eyna tzricha because bracha l'vatala appears to me the case of saying the bracha and then not drinking). This is particularly true for one who knows he sometimes forgets.

By coincidence I saw R Daniel Mann wrote yesterday

[...] as the term she’eina tzricha (unnecessary) implies and the Orchot Chayim (Berachot 15) states, the problem is only when the additional beracha is created for no good reason. When, in contrast, there is a need for his actions, the beracha is not considered unnecessary.
