Even though you use smoothtriangles in the image the rays are computed
using the underlying triangles. This means that if the glass and wine
have same size of triangles, you are sure to have some overlap, if
they are rotationally not aligned. Indeed using some space between
the two object should get rid of it and you say it did not. (Athough
not knowing the scale of the triangles i do not know if .1 mm is enough)
Anyway, to test if it has anything to do with this kind of overlap, try
rotating the wine a bit and not the glass.
