Making beer is the process of putting sugar in water and then allowing yeast to convert that sugar into alcohol.
I'm not sure what point you mean when you say "brew up to that point", but if you don't add sugars of some kind you'll just have hops and water. There are ways of removing alcohol from beer, and there are beverages made from malt without yeast, but there is no beer without sugars of some sort or another.
(Carbonation drops are also sugar.)
