Ali Ibn Ja’far (a.) reported that he asked Imam Al-Kazim (a.) about:“The drunkenness leading drink (Khamr), which in the beginning was a drunkenness leading drink, whereupon it turned into vinegar. Is it to be consumed?” Whereupon he said: “Yes, if that which leads to drunkenness has disappeared from it, there is no objection to it.” [Al-Masa’il of Al-Uraidi, page 155 Hadith 215]

عن علي بن جعفر عليهما السلام عن الإمام الكاظم عليه السلام قال: وسألته عن الخمر يكون أوله خمرا ثم يصير خلال أيؤكل؟ قال: نعم إذا ذهب سكره فلا بأس
