Sorry for chiming in: Do you mean that you have seen another type
of glass stopper, just not this one, or no glass stopper at all?

To the best of my knowledge, this type (Vino-Lok) is the only one,
and it's used in Austria and Germany since around 2003, but I'd
estimate the penetration rate well below 5% for them. (Screw-caps
in Austria, otoh, have a market share of over 70% of the whole
production.)
