I am a big fan of fine glassware. My cupboards are filled with Spiegelau and Riedel glasses and stemware. Needless to say, that despite these being great glasses, they are also delicate like a baby’s bum and need to be handwashed. I have on more than a few occasions broken a glass simply by washing it too hard. The other issue is trying to dry them without spots. You don’t really want to rest them on the rim for fear of tipping and breaking.
