Cidersugar - I make beer and get very good carbonation with 3/4 cup sugar
per 5 gallons. Since you want lower carbonation that a typical beer try 1/2
cup sugar per 5 gallons. You will still get some carbonation but not a big
head like a Pilsner beer. More like a British Ale. The 1/2 cup corn sugar
will weigh about 70 grams.

I would just go ahead and use corn or table sugar for the carbonation. But
if you want to use juice here's a way to estimate the fermentable extract
(sugar?) in juice.

Water weighs about 8.329 lbs/gallon.
Calculate the weight of one gallon juice in pounds [sp.gr.*8.329]
Convert the specific gravity to Brix
[here's a simple conversion; Brix = [(259/sp.gr.)-259]*[-1]
Calculate the weight of extract in juice [(weight of 1 gallon juice *
Brix)/100]
Now you know how many pounds of extract is in a gallon of juice.
Convert to grams and you can calculate how many gallons of juice will be
needed to provide 70 grams of sugar.

Note: This assumes all the extract is fermentable. If you are working with
clear apple juice this is probably a good extimate.
