Bava Batra 97B

דאמר רבא: סוחט אדם אשכול של ענבים, ואומר עליו קידוש היום!

As Rava says: A person may squeeze the juice from a cluster of grapes and then recite the sanctification of the Shabbat day over it.

ואלא למעוטי מפיה ומשוליה? והא תני רבי חייא: מפיה ומשוליה לא יביא, ואם הביא ⁠– כשר!

Rather, Rav’s statement is to exclude wine that is taken from the mouth of the jug, which has scum floating in it, and wine taken from the bottom of the jug, which contains the pomace. The Talmud challenges this: But didn’t R' Ḥiyya teach: One may not bring wine that is taken from the mouth of the jug or from the bottom of the jug as a libation ab initio, but if one brought it as a libation it is valid after the fact? Accordingly, it should be fit for use for the sanctification of the Shabbat day.

ואלא למעוטי יין כושי; בורק; היליסטון; של מרתף; של צמוקים? והא תניא: בכולן לא יביא, ואם הביא ⁠– כשר!

Rather, Rav’s statement is to exclude black wine, borek wine, sweet wine [heiliston], wine from the cellar, and wine made from raisins. The Talmud challenges: But isn’t it taught in a baraita: With regard to all of these types of wine, one may not bring them as a libation ab initio, but if one brought one of them as a libation it is valid after the fact. Accordingly, it should be fit for use for the sanctification of the Shabbat day.

ואלא למעוטי יין קוסס; מזוג; מגולה; ושל שמרים; ושריחו רע ⁠– דתניא: בכולן לא יביא, ואם הביא ⁠– פסול.

Rather, Rav’s statement serves to exclude souring wine, diluted wine, wine that has been left uncovered, as there is a concern that a snake may have injected its venom into it, and wine made from grape pomace, and wine that has a foul odor. As it is taught in a baraita: With regard to all of these types of wine, one may not bring them as a libation, and if one brought one of them as a libation, it is disqualified.
