A big chunk of a day's sugar in one serving.

Grape Juice carries roughly 27 g of sugar per 8 fl oz, which works out to about 10.9 g per 100 g. That places it in the 'high' band for a typical serving.

Because this sugar occurs naturally in the food itself, it typically comes packaged with fibre, water, or other nutrients that slow how fast it hits your bloodstream — unlike the same amount of sugar added to a processed product.
