Kashrut: Open, Uncooked Wine: Drinking or Benefiting From

You may not DRINK or DERIVE ANY BENEFIT FROM open (unsealed), non-mevushal (uncooked, previously kosher) wine or grape juice that has been handled by:
  • A non-Jew, or
  • Any Jew who intentionally does not observe the laws of Shabbat.
Note Even though some people are not stringent about this, they should be since the prohibition is from the Talmud.
Note “Deriving benefit” includes that you may not sell it, feed it to an animal, etc.
Note There may be exceptions for cases involving large losses. A large loss is subjective to the individual's actual wealth and also to that person's perception of what is a large loss. Consult a rabbi.
