If you want to be fancy about your screw cap bottle of wine (not to say that you can’t…I’m all in favor of the screw cap) then call it a Stelvin closure. People ‘in the know’ about wine never say screw cap they say Stelvin closure.
Stelvin closure is like Kleenex in that it is a brand that has become a generic. Unfortunately, I can not find why it is called Stelvin! Do you know?
