Everything that is taken from the date palm or grape vine and steeped is called Khamr
وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا وَكِيعٌ، عَنِ الأَوْزَاعِيِّ، وَعِكْرِمَةَ، بْنِ عَمَّارٍ وَعُقْبَةَ بْنِ التَّوْأَمِ عَنْ أَبِي كَثِيرٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْخَمْرُ مِنْ هَاتَيْنِ الشَّجَرَتَيْنِ الْكَرْمَةِ وَالنَّخْلَةِ " . وَفِي رِوَايَةِ أَبِي كُرَيْبٍ " الْكَرْمِ وَالنَّخْلِ " .
Abu Huraira reported Allah's Messenger (ﷺ) as saying: Wine comes from vine and date-palms. Abu Kuraib has narrated it with a slight variation of words.
