Glass cork


Last week, I went to open a bottle of rose wine and discovered it had a glass 'cork'. I'd never seen such a thing, so I kept it to investigate further. It looked rather elegant but was so tight fitting that it was hard to open. 

Then I did a little research which led me to an article in the WaPo. I learned that glass 'corks' or stoppers are quite popular in Europe but have not been accepted in America. 

The company that makes them is Called Vinolok. They market them for pink wines. They come in a variety of shapes and colours, and the premium collection looks like decanter stoppers. They use the name Vinoseal in Europe but the URL defaults to Vinolok. Their catalog has many versions including a bespoke version that can be custom designed to any shape. 

They even make bottles for premium spirits and wines. Very nice. 

The Vinolok closure has such a tight seal that there is no loss, no air intrusion and no need for sulfites. It doesn't impart any flavours as synthetic corks can. It's not as easy to open as a screw cap, but it does impart a premium impression. It is easy to bottle manually, taking just 1 hour to bottle and seal 1000 bottles. 

I'll research bottles and other packaging for another article. But the cry has gone out to manufacturers of glass bottles to make lighter weight bottles to reduce the carbon footprint and the cost of heavy glass bottles and their shipping.
