Both images are of high quality indeed.

I /am/ a wine drinker, but I just use a simple Duralex glass (those with 
9 facets). I still have an average wine glass which gradually thins 
towards the rim indeed, but starting from a slightly thicker base than 
in the images, towards an identical thickness at the rim.
