סימן מט סעיף ב
הַחַרְצַנִּים שֶׁהוֹצִיאוּ מֵהֶם הַיַּיִן רַק עַל יְדֵי דְּרִיכָה וְלֹא נֶעֶצְרוּ בְּבֵית הַבַּד, אִם נָתְנוּ עֲלֵיהֶם מַיִם, אֲפִלּוּ לֹא מָצְאוּ יוֹתֵר מִמַּה שֶּׁנָּתְנוּ, אוֹ אֲפִלּוּ מָצְאוּ פָּחוֹת, מִכָּל מָקוֹם אִם טָעְמוֹ יַיִן מְבָרְכִין עָלָיו בּוֹרֵא פְּרִי הַגָּפֶן. אֲבָל אִם נֶעְצְרוּ הַחַרְצַנִּים בְּבֵית הַבַּד וְאַחַר כָּךְ נָתְנוּ עֲלֵיהֶם מַיִם אוֹ שֶׁנָּתְנוּ מַיִם עַל שִׁמְרֵי יַיִן, אֵינוֹ אֶלָּא כַּמָּיִם.
Concerning grape seeds from which wine was extracted only by means of trampling, but which were not pressed in a [heavy duty] wine press, the following should be noted: if water was poured upon them, even if they recovered no more [water] than they poured [on them],6If the recovered liquid would be greater than the amount poured in, this could indicate that there was wine still absorbed in the seeds which was released with this new pressing. The berachah would obviously be Borei peri hagafen. More so, the author states, even if the volume of liquid poured was equal to or even greater than the amount recovered, the berachah would still be Borei peri hagafen, provided that the recovered liquid has the taste of wine. or even if they recovered less, nevertheless, if it has the taste of wine, the berachah is Borei peri hagafen. But, if the seeds were pressed in a [heavy duty] wine press and then the water was poured on them or they poured water upon the residue [in the vat from which all the seeds were removed],7This is known as “wine lees”—a yeasty substance which, when mixed with water, produces a tangy tart drink. it is considered as water.8It is assumed that all the wine remaining in the seeds has been removed by the heavy-duty press. Wine lees is considered shemarim—yeast, a fermentation agent.
