So I finally kegged this last night - gave it a good sit in the secondary... its at 8.4%.
Couldn't help it, poured half a glass, warm and flat, and since it finished at 1.022, it is quite sweet - but this is absolutely !@#ing great! I will be making this again...
So the candi sugar is very evident. It tastes nothing like what one would expect from table sugar - I understand now why one would use this...
