I might need a help with my first cider brew. I’ve made wine in past it was all based on natural yeast, had my recipe that contained water with whatever berries I was making it.

I tried making cider, put 4 liters of apple juice from market (natural juice, but still, packed), 1.5l redcurrant berries (frozen, blended, fermented in a bag) and 2 liters of water. I added yeast and everything it needed, 6 days have passed now, hidrometer is very close to 0 and while it tastes ok, I think it tastes quite watered. I plan to sweeten it a bit (still, dry or semi dry) but have no idea how to make it more saturated (taste wise).

Is there anything I can do, especially at this stage?
