Avodah Zarah 33b
עבודה זרה ל״ג ב — ד"ה לְכַתְּחִלָּה אוֹ דִיעֲבַד
Avodah Zarah 33b:1
Discusses koshering wine vessels and the treatment of containers associated with non-Jewish wine. The sugya supplies the Talmudic basis for concerns about absorbed wine taste in wooden vessels.
לְכַתְּחִלָּה אוֹ דִיעֲבַד? תָּא שְׁמַע, דְּתָנֵי רַב זְבִיד בַּר אוֹשַׁעְיָא: הַלּוֹקֵחַ קַנְקַנִּים מִן הַגּוֹיִם — חֲדָשִׁים נוֹתֵן לְתוֹכָן יַיִן, יְשָׁנִים — נוֹתֵן לְתוֹכָן צִיר וּמוּרְיָיס לְכַתְּחִלָּה. אָמַר רַב עַוִּירָא: הָנֵי חַצְבֵי שְׁחִימֵי דַּאֲרַמָּאֵי, כֵּיוָן דְּלָא בָּלְעִי טוּבָא — מְשַׁכְשְׁכָן בְּמַיִם וּמוּתָּרִין. אָמַר רַב פַּפִּי: הָנֵי פַּתְוָותָא דְּבֵי מִיכְסֵי, כֵּיוָן דְּלָא בָּלְעִי טוּבָא — מְשַׁכְשְׁכָן בְּמַיִם וּמוּתָּרִין. כָּסֵי — רַב אַסִּי אָסַר, וְרַב אָשֵׁי שְׁרֵי. אִי שָׁתֵי בְּהוּ גּוֹי פַּעַם רִאשׁוֹן — כּוּלֵּי עָלְמָא לָא פְּלִיגִי דַּאֲסִיר, כִּי פְּלִיגִי בְּפַעַם שֵׁנִי.
Is it permitted to put brine or fish stew in the wineskins ab initio, or is the substance permitted only after the fact? The Gemara suggests: Come and hear a resolution to the dilemma, as Rav Zevid bar Oshaya teaches: With regard to one who purchases jugs from gentiles, if they are new, he may place wine in them, and if they are old, he may place brine and fish stew in them ab initio. Rav Avira said: With regard to these dark brown Aramean jugs, since they do not absorb substances well, one need only scrub them in water and they are permitted. Rav Pappi likewise said: With regard to these earthenware vessels from Bei Mikhsei, since they do not absorb substances well, one need only scrub them in water, and they are permitted. The Gemara continues: The halakha with regard to cups, which hold wine only temporarily, is subject to a dispute: Rav Asi prohibited them, and Rav Ashi permitted them. The Gemara comments: If a gentile drank from a cup for the first time, i.e., it had never been used before, everyone agrees that it is prohibited, as a new cup absorbs a great deal of wine in its first usage. They disagree when it is being used for a second time, i.e., the cup has already absorbed a permitted liquid, and therefore its capacity to absorb the gentile’s wine is impaired.
