I am making a ginger beer and I do not know if I should use caster sugar as a subsitiute for my cane sugar, as I do not have any. Is this OK?

Yes you can, so long as you work by weight not volume. Unrefined cane sugar (or refined sugar with some molasses added back in) would contribute a little to the flavour, but sugar mainly provides sweetness, and in brewed ginger beer, a source of nutrients for the culture.

Caster at the same volume as granulated would be too sweet (the finer crystals mean more will pack into the same space), but at the same weight it would be fine.

    I agree with your answer, it may be worth explaining why. Caster sugar is plain sugar that is finer than granulated or unrefined cane sugar. Finer means more will fit into a unit of volume.
