Reference for Maasrot 1:7
הַיַּיִן, מִשֶּׁיְּקַפֶּה. אַף עַל פִּי שֶׁקִּפָּה, קוֹלֵט מִן הַגַּת הָעֶלְיוֹנָה וּמִן הַצִּנּוֹר, וְשׁוֹתֶה. הַשֶּׁמֶן, מִשֶּׁיֵּרֵד לָעוּקָה. אַף עַל פִּי שֶׁיָּרַד, נוֹטֵל מִן הֶעָקָל וּמִבֵּין הַמָּמָל וּמִבֵּין הַפַּצִּים, וְנוֹתֵן לַחֲמִטָּה וְלַתַּמְחוּי, אֲבָל לֹא יִתֵּן לַקְּדֵרָה וְלַלְּפָס כְּשֶׁהֵן רוֹתְחִין. רַבִּי יְהוּדָה אוֹמֵר, לַכֹּל הוּא נוֹתֵן, חוּץ מִדָּבָר שֶׁיֶּשׁ בּוֹ חֹמֶץ וְצִיר:
Wine, from when he skims [the scum from its surface]. Even though he has skimmed, he may collect from the upper winepress and from the pipe and drink. Oil, from when it falls into the trough. Even though it has fallen, he may take from the olive pulp bale and from between the olive press-stone and from between the board and put it on the batter-cake or on the plate, but he may not put it in the pot or in the stew-pot when they are boiling. Rabbi Yehudah says, he may put it in anything, except for something that has in it vinegar and brine.
