This Mishnah will talk about what got mixed with other foods. Mishnah says, if it fell onto grapes and he rinses them off with water so that there's no more wine on them, they're permitted. The wine never got absorbed into the grapes, so simply washing them off would remove all of the, and they would be permitted again. But if the skin of the grapes was cracked a little bit, then when the wine fell into the grapes, it went inside the grape. Washing it out is not going to do anything, because the inside of the grape mixes together with the wine. In that case, it's prohibited. We assume that the wine seeped all the way in and cannot be washed out. Or, if it fell onto figs or dates, even if the skin wasn't cracked, the fruit is very soft, and the wine automatically goes through the skin. Washing it in cold water won't do anything. If there's enough wine in there to give flavor, so that you can taste the wine in the figs or dates, that would be enough to prohibit eating those dates or figs.
Ma'aseh Beitus ben Zonin. There was a situation where an individual by the name of Beitus ben Zonin. He brought dried figs onto a boat, and, as the Mishnah continues, a wine of Yayin Nesech (libation wine) broke, and that wine spilled onto these dried figs. He asked the rabbis about these dried figs: “What's the story with them? Are they edible halachically?” And the rabbis permitted them, even though the flavor of the Yayin Nesech seeped into the dried figs. Hachamim (rabbis) said that they still are permitted because the wine that seeped into the dried figs gives them an unpleasant taste, gives them a negative taste, as opposed to the fresh figs that we had in the beginning of the Mishnah, which gave a good taste. Here, even though the wine seeped in, the taste was a bad taste, and therefore the rabbis allowed these dried figs to be consumed.
Zeh haklal, this is the general rule about forbidden foods that mix with permitted foods. Kol shebehana'ato benoten ta'am: any forbidden food whose taste enhances the mixture, so that when it falls into the permitted food, what you had is now a mixture of the permitted food and the forbidden food, and that forbidden food gave it a better taste. Asur: in all these cases, it's prohibited to consume; it's prohibited to consume it. Kol she'ein behana'ato benoten ta'am: but in any case where the forbidden food that fell in is not beneficial to the mixture, it harms the actual taste. In that case, Mutar: it's permitted to consume the mixture. What's an example of that, where something not kosher falls into something kosher and it hurts the taste? Kegon Chometz shenafal al gabei grisin. It's an example. It would be vinegar from Yayin Nesech that fell into split beans. It hurts the taste, and therefore the split beans would become prohibited to consume.
