מכאן ואילך — אין בו משום גילוי, ואין בו משום יין נסך. ונהרדעי אמרי: אפילו לבתר תלתא יומי חיישינן משום גילוי. מאי טעמא? זימנין מיקרי שתי.
From this point forward, it is not subject to the halakha of exposure and is not subject to the prohibition of wine used for a libation. And the rabbis of Neharde’a say: Even after 3 days, we are concerned with regard to exposure. What is the reason? It is because at times it occurs that a snake drinks even sour wine.
תנו רבנן: יין תוסס אין בו משום גילוי, וכמה תסיסתו? שלשה ימים. השחלים אין בהם משום גילוי, ובני גולה נהגו בהן איסור. ולא אמרן אלא דלית בהו חלא, אבל אית בהו חלא — מיגרי בהו.
§ The Talmud discusses the halakha of exposure with regard to various foods and beverages. A baraita states: Wine that is still fermenting is not subject to the halakha of exposure. And how long is its fermentation process? It is 3 days. Cress-based dishes are not subject to the halakha of exposure, but the residents of the Diaspora are accustomed to treating them as prohibited if they were left exposed. And we said this only in a case where the dishes do not contain vinegar; but if they do contain vinegar, the vinegar repels the snakes, and in such a situation even the inhabitants of the Diaspora do not treat them as prohibited.
כותח הבבלי אין בו משום גילוי, ובני גולה נהגו בו איסור. אמר רב מנשי: אי אית ביה נקורי — חיישינן. אמר רב חייא בר אשי אמר שמואל: מי טיף טיף אין בו משום גילוי. אמר רב אשי: והוא דעביד טיף להדי טיף טיף.
The Talmud continues: Babylonian kutaḥ, a popular dip, is not subject to the halakha of exposure, but the residents of the Diaspora are accustomed to treating it as prohibited. Rav Menashei said: If the kutaḥ has indentations in it, we are concerned that they are from a snake’s fangs, and it is therefore prohibited. Rav Ḥiyya bar Ashi says that Shmuel says: Dripping water is not subject to the halakha of exposure while it is being collected. Rav Ashi said: And that is the halakha only in a case where the dripping occurs one drop immediately after another drop, i.e., continuously, as the snake will not drink from it in that circumstance.
