New type of closure?

I had this with supper last night, and it was the first time I'd ever seen a closure like this.

We had a thread on Zorks several months ago, but I've never seen one either. Zork Closure
A home winemaking website I frequent also recently had a thread on the subject. Apparently they can be used on standard wine bottles and are not too expensive for home winemakers to experiment with. LINK

I currently have a couple of dozen bottles in the cellar under this type of closure. Mine are from Germany and Austria.

Only ones i remember having are German ....I really like them... better than screwtop...and you can reuse the bottle for, say, olive oil and have a tight closure

I've seen plenty of German/Austrian bottles under Vino-lok, but never Zork. Which estates are doing Zork?
