This is rather my way of doing things. #1 rule of wine glasses is, they get broken. The more you use them, the more likely you are to break them. Taking them outside, the more likely they are to get broken. So you have different glasses for different occasions.
Yeah, wine glasses breaking is an occupational hazard that is bound to happen - not just with the frequency of their use, but also with the amount of wine you drink with them at one usage.
Goomba, just make sure that the lip does not have a "bead" on it, like this one:
Otherwise, you are prudent in getting some Spiegelau glasses.
