Sunan an-Nasa'i, Volume 6, Book 51, Hadith 5752 (DarusSalam)

It was narrated that Abu Al-Miskin said: "I asked Ibrahim: 'We take the dregs of Khamr or Tila' (thickened grape juice) and clean them, then we soak it with raisins for three days, then we strain it and leave it until it matures, then we drink it.' He said: 'That is Makruh.'"

أَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ أَبِي عَوَانَةَ، عَنْ أَبِي مِسْكِينٍ، قَالَ سَأَلْتُ إِبْرَاهِيمَ قُلْتُ إِنَّا نَأْخُذُ دُرْدِيَّ الْخَمْرِ أَوِ الطِّلاَءَ فَنُنَظِّفُهُ ثُمَّ نَنْقَعُ فِيهِ الزَّبِيبَ ثَلاَثًا ثُمَّ نُصَفِّيهِ ثُمَّ نَدَعُهُ حَتَّى يَبْلُغَ فَنَشْرَبُهُ قَالَ يُكْرَهُ ‏.‏
