Bit new to this but already have four kits under my belt (mostly woodfordes) and all great so far!

Anyway, its on its 11th night of brewing and the SG isnt getting any lower although Co2 is still being verryy slowy produced. Its not at 4.5 % so I'm thinking
1. Add some sugar to get the alc up (maybe half a kilo?)
2. Leave it for a bit longer (although Ive already gone past the six days)
3. Bottle it!
Thanks for any help / advice
Andy
