Rabbi Baruch Bodenheim: Gemara Shabbos: Borer – Monday night shiur, Shevat 9 – Filtering Water (01/26/26)

Filtering water

Very quickly review גמרא דף קלט עמ’ ב “אמר זעירי נותן אדם until the two dots 

What is the answer of the Gemara of בין הגתות?

Major Question:

Why does it matter that people drink the wine with the sediments? Why should that permit one to filter out the sediments if he personally does not want the sediments in his wine? How is this different from a person who has a mixture of two food items and one of them he does not want to eat now – which is forbidden for him to separate as the one he does not want is considered – bad-‘ pesoles -waste?
