Just a very low alcohol?
Terrible taste?
Just curious. You know, incase someone were to do something like that.
Oh, and would it be too late to add the rest of the sugar say 5 days into fermentation? Just incase someone did do that

I guess it helps to read the label clearly. 1KG of sugar looked like 1LB of sugar but unless my math is off, 1KG of sugar is actually about 2.25Lbs of sugar.. I was a bit short and didnt notice until reading the instructions again 5 days later.
