Glad to see I’m not alone in a slightly anal obsession in always drinking from a perfectly clean wine glass
I wouldn’t use a dishwasher for wine glasses. I’d also avoid turning them upside down on a cloth to dry them: this can make the rim a bit smelly. It’s really worth the effort of washing glasses well before you put them away, because then you can use them without worrying about whether they are going to be smelly or not. If you are in doubt about a glass, a quick rinse with wine primes the glass nicely.
