Musnad Ahmed: Hadith 2751

The Messenger of Allah (ﷺ) forbade gourds, green glazed pitchers, hollowed-out stumps and varnished jars, and he forbade mixing dates once they begin to ripen (balh) with unripe dates that have begun to take on a red or yellow colour (zahw). I said: O Ibn 'Abbas, what do you think about a man who makes his nabeedh in his green earthenware jar that is like a bottle, and he drinks it at night? He said: No, refrain from what the Messenger of Allah (ﷺ) forbade to you.
