some glasses are thin ; what i mean if i don't modeled drops and used a sphere object in studio the scattered spheres will intersect with glass and liquid at the first time

I'm sorry but I still don't understand what you mean...This glass bottle for example, needs a proper wall thickness to render refractions properly, just as the regular bottle would have a wall thickness of say 2-3mm. In this way, any bubbles you may have on the outside of it will surely have a small enough diameter so that they can't touch any liquid inside the bottle. Do you see what I mean?

i didn't speak about the bottle only
in general we need give the drops always lower priority becuase we can't ensure that they will not intersect with liquid ; if we use spheres or thik drops
