I guess if all you had was powdered sugar it would work, but like someone just said, dissolve regular old sugar in warm water and let it dissolve, if, this is a question of dissolving.
I recently made a batch of apple wine using brown sugar, I wasn't all that impressed. For now just give me old fashioned granulated sugar.
If I ever start another batch of strawberry, I MAY try brown sugar again.
But, speaking of old fashioned, I am apprehensive to try to replace something, with something new, especially if it works.
So for now, I'm sticking(pardon the pun) with G Sugar.
