Reference for Terumot 8:4

יַיִן שֶׁל תְּרוּמָה שֶׁנִּתְגַּלָּה, יִשָּׁפֵךְ, וְאֵין צָרִיךְ לוֹמַר שֶׁל חֻלִּין. שְׁלֹשָׁה מַשְׁקִין אֲסוּרִים מִשּׁוּם גִּלּוּי, הַמַּיִם וְהַיַּיִן וְהֶחָלָב. וּשְׁאָר כָּל הַמַּשְׁקִין מֻתָּרִים. כַּמָּה יִשְׁהוּ וְיִהְיוּ אֲסוּרִין, כְּדֵי שֶׁיֵּצֵא הָרַחַשׁ מִמָּקוֹם קָרוֹב וְיִשְׁתֶּה:

If wine that is <i>Terumah</i> is left uncovered, it must be poured out. It is not necessary to say this if it is <i>Chulin</i> [non-sacred produce]. Three kinds of liquids become forbidden if left uncovered: water, wine, and milk. All other liquids [even if left uncovered] are permitted. How long must they be left [uncovered] for them to become forbidden? As long as [it would take] for a snake to come out from a nearby place and drink [from it].
