Mixing yeast with sugar to produce CO2

Answered according to Hanafi Fiqh by

Q: There is a Hadith that states: “Allah has cursed wine, the one who drinks it, the one who serves it, the one who sells it, the one who purchases it, the one who presses it, the one who manufactures it, the one who transports it and the one to whom it is delivered.” (Abu Dawood, #: 3676, Narrated by Abdullah bin Umar) What exactly does wine/alcohol mean? I am in the planted aquarium hobby. One of the practices is to make DIY CO2. This involves mixing yeast (baking or brewers yeast) with sugar, to produce CO2, that is transported to the tank in order to improve plant growth. The yeast/sugar mix eventually turns into alcohol, and thereafter is replaced with a new mixture. For a full article on the procedure, please refer to… Does such mixtures fall into the above Hadith?


A: To produce alcohol is also impermissible.

And Allah Ta’ala (الله تعالى) knows best.
