Do corks for bottles have a direction?

When wine bottle corks are cut from the cork bark, is the cork cut vertically or horizontally through the section of bark? In other words, is there 'grain' directionality in the cork bark that matters in terms of it's function as a wine bottle cork?

According to this it's vertically.

Since cork is bark and appears to grow outward from the trunk, any possible grain would be parallel to the surface of the tree. But it doesn't appear to have grain.

Traditional wine corks and other cork stoppers aren't made from the cork that grows on the tree as it grows up from a sapling because that cork is like the cork of other trees (ridged and very uneven in depth, albeit thicker), and so useless for the purpose.

Wine corks are made from "reproduction cork" which grows on cork oaks when the original bark is stripped off.

Reproduction cork is a solid, uniformly thick layer under ideal conditions.

It's been a while since I had a bottle of wine which had a cork not composed partly of compressed fragments of cork, though.

I'd say horizontal, but maybe we're saying the same thing. There's a very clear picture in the linked article.

It's funny that you bring this up because it was just a post on Metafilter.

On preview, exactly what Yellow posted.
