Coopers Australian lager kit. Substituted the 1kg of sugar for 1kg of brew enhancer ( I know it's just different sugars ) added 1/2 kg of very light spray malt, just playing with the recipe a little. OG was 1.042 now nine days the FG is 1.012 and that's been the same for four days, was expecting it to come down to 1.006, is this ok to bottle? Any reason as to why it's not come down further , I'm only six months in to the hobby and don't pretend to know it all, thankyou.
