371. Seedless: The prohibition against a nazir eating grape seeds
…from the seeds… (Numbers 6:4)
As we have said, the nazir could not eat any part of the grape, including the seeds.
This mitzvah applies to both men and women in all times and places. It is discussed in the Talmud in tractate Nazir on pages 34a-35a. It is codified in the Mishneh Torah in the fifth chapter of Hilchos Nezirus. This prohibition is #205 of the 365 negative mitzvos in the Rambam’s Sefer HaMitzvos; it is not listed in the Sefer HaMitzvos HaKatzar of the Chofetz Chaim.
