Hi recently returned to winemaking,made two gallon of cherry ,they have been in demijohns for a couple of weeks,starting sg 1.1 now down to sg 1.03 ,i have racked into clean demijohns today as there was an inch or so sediment in each ,so i now have 1 full demijohn one three quarters full and a 2 litre plastic bottle with the remnants all under fermentation locks (see photo).so question is should i leave the second part filled demijohn or what? thanks for your help.
