It works best if you bottle it into suitably small bottles (I use 1 Ltr screw top PET beer bottles) and if your Booch is somewhat tart, add a small amount of sugar when you bottle to feed the residual yeast.
I too use lemon & ginger; 2 lemons juiced and about 250 g of ginger juiced for my normal batch size of 20 liters. It takes about 12-14 days to carbonate at room temperature. Refrigerate when suitably fizzy.
