I have this on a couple of news groups (home-brewing & winemaking)

I just bought 5 gallon of apple juice to make cider with. The juice has a
total of 2,000 grams of sugar which is about equal to 10 cups (9.92025 cups)
of sugar. I usually use about 15 cups of sugar in 5 gal of cider. Is the
sugar in the juice the same as the sugar that I have been using (Cane
Granulated Sugar) and will I only need to put 5 cups of sugar in the 5 gal
batch to achieved the same results.
