משנה על עבודה זרה 2:1

If wine of terumah was left uncovered, it must be poured out, and there is no need to say this in the case of hullin. Three kinds of liquids are forbidden if they were left uncovered: water, wine and milk, but all other drinks are permitted. How long do they remain uncovered for them to become prohibited? The time it takes the snake to creep out from a place near by and drink.

One must not put a cake of pressed [terumah] figs or dried [terumah] figs into fish-brine, since it spoils them. But one may place [terumah] wine into fish brine. One must not perfume the oil, But one may put honey and pepper into wine. One may not boil terumah wine, because it decreases it. Rabbi Judah permits this, because it improves it.
