if I were to make a fruity rose with 1L RGJ, 1L Apple Juice & 1L of cherry/peach etc, would I top up the rest with water? so like 1500ml? (only making 4.5L demijohn batches at the moment)
You could top up with juice but i think it will taste great topped up with water.
I have 2 bottles of RGJ & 4 cartons of apple juice. could I get 2 batches out of that?
I only use 1 litre of each juice in a DJ then top up with half a litre of apple juice so you have enough to make 2 DJ's (a litre of RGJ and a litre of Apple juice) with a litre of apple juice to top up or you could leave enough head-space to top up with a full litre of apple juice in each.
