Hi I have a 20l batch of turbo cider which I made last Sunday and have just taken a hydrometer reading this morning which is 1045 from an original 1055 I was expecting it to have just about finished. I have made the same recipe several times now and all went very well. So 20l apple juice 1k sugar 2tsp yeast nutrient 1pk lalvin 1118. I have just given it a stir and it seems very fizzy. Smells OK. Fermented at 20°. Any advice please.
