Not sure, but I've made wine bottles out of chocolate using a mold. It is a lot easier. You could use white chocolate and paint it green or gold the color of a beer bottle.
The pics are so small, I can't tell what I'm looking at. Did the bottles collapse? Where I'm located, it is SO humid, I wouldn't dream of trying to make sugar bottles right now. What's gonna happen is, the sugar will be overcooked (hence the yellow bottle in your pic) and then the finished product will either collapse or never hold it's shape in the first place. You might be dealing with humidity.
It looks like the sugar may not have completely coated the inside of the mold. I had small holes in the neck of two of my bottles because of that. Try rotating the bottles VERY slowly while pouring the sugar in and then continuing to turn the mold so the sugar spreads evenly. I would turn the mold while peeking inside until the sugar stopped spreading. Then I would try to start pouring new sugar in the area I had stopped at. Hope this helps.
I think maybe you don't have enough sugar mix. How much did you use? You probably quit turning the bottle before it was cool enough also. The yellow is because the sugar was a little over-cooked. Clear bottles are the hardest because there is a fine line between puddle and yellow.
