Now here is a wine truism. Thin is in. It's simply better, to a point. Having very thin glass for your bowls puts lets between you and your wine, allowing you to put the wine right into the front of your mouth, making sure each mouthful gets to excite each and every one of your erudite taste buds.
Thick glass, rolled rims, or even many ridiculously ill-conceived bowl e designs have the wine pouring out onto the middle of your mouth, or even dribbling out around the edges, neither of which makes for a pleasant drinking experience.
You can get too thin, not for drinking but for actual real world use. I had some of those very thin and expensive glasses. I looked at one funny once and it broke from the shame. Yes, from pure shame.
