Glass Closure

So, I'm not one to be overly surprised by anything these days, but we received a Syrah from the state of Washington the other day which had the following as a closure:

 My wife did get a good laugh as I had taken out the bottle opener only to look rather confused when I first pulled the cork.

In any case, have you ever seen one?

The good news about glass is that TCA (corking of wine basically) can't happen and of course glass is 100% recyclable.

The usual caveats apply of course including consumer sentiment (still strongly toward cork by most accounts) and the fact that it's still highly unusual.
