Boy, that spiral has to be a bear to clean, though, especially if the glass sits overnight.

what is wrong with decanting the wine

@Ron
If your help is letting your glasses sit unattended overnight you should probably replace them anyways.

I hope some kind of ultrasonic cleaning device comes with the glasses.

Connoisseurs (winos, IOW) have been putting up with debris in their glasses for _that_ long? Har! Lots of class, that. Glad I sobered up in '85, and never was a wine drinker. Well, I hope the glassmakers do a brisk business with all of them.

".. it's quite astonishing that this simple design hasn't been done before."
There are 2 very good reasons that explain this fantastic riddle.
1/ Cleaning (as others have pointed out) 2/ $35 *PER GLASS*!!!
Yet another hopelessly impractical answer to a non-problem destined for the dustbin of history.

Oh, man! I was going to say those things but everybody beat me to the comments. Thank you, smart commentors for pointing out that we really don't need this product. Just another answer in search of a problem.

I guess you could use a filter to remove sediment from the liquor. The solution probably doesn't need to be so complicated. Also: bleah! Wine is just gross. So are the winos who chug it. Whatever happened to "rotting grape" brand wine, I always got a laugh at that. What kind of person buys such rot?

Surely wines have been sediment-free for decades?

"Wine is just gross. So are the winos who chug it."
What makes you such an anti-wine zealot? Or gives you authority to abuse those who drink it?
