Cork? Screwtop? Glass?

Because I bottle my own cordial, I am always on the lookout for the right bottles in the town recycling bins. I recently pulled an odd one out with a glass stopper. And this morning happened across the maker on Instagram - vinoseal_glass_closure where they show the various uses made of their product. If you like elegant presentation, do check them out.

So I googled them and found an industry article or two:

The seal is made of DuPont Elvax, a supposedly inert food grade plastic resin.

I knew I had saved a relevant article, and found it today. Also found it online. Wine writer, Lettie Teague has written about cork versus screw cap :

She says screw caps provide more quality control and obviate the occasional failures of cork. Cork might still be wanted for wines that want to be aged; but it’s mostly a question of tradition and perception anymore.

I know that many good winemakers have been using screw tops for a while now and I'll buy a wine without noticing if it's corked or screw top. It still surprises me though, and it feels like cracking open a bottle of Boone Farm, ha!
