Fermentation problems with ginger beer

[chaunceyflogginbottom]

I have a five gallon batch of ginger that doesn't seem to have fermented properly. I used yeast nutrients but I have used too little sugar. Upon adding more sugar 6 days in, all bubbling has stopped. What should I do?

Rock the fermenter to keep the yeast in suspension.

How much sugar total did you use? How did you add the sugar? Did you dissolve it before adding?

I started with 7 cups. And added 4 more dissolved in 2 cups water
