Coopers Ginger Beer Carbonation

[mikeBt]

I want to put a NON-alcoholic Coopers Ginger beer together for my kids and then bottle in different sized Pet soft drink bottles. When I try to convert the instructions on the back of the can it makes it difficult because it only talks about carbonation drops. I don't know how much sugar is in one drop. Does anyone have a good idea about how much sugar I will need for 19 litres of Cooper's non-alcoholic GB. I have tried looking on this site and googling but only come up with alcoholic recipes etc.

Cheers Mike

PS I made a Morgans, and from memory it required 110 grams in the fermenter for 30 mins which is different from the Cooper's. Would this suit my brew?

I did one this afternoon, 200 grams for 30 minutes, total volume 20 litres. Carbination drops are 3 grams AFAIK.
