black synthetic cork

One of a collection of 8 synthetic cork bottle stoppers. This example is black in colour and is unprinted. There are two main methods of production of synthetic wine corks, namely injection moulding and extrusion. Advances have been made in production techniques which aim to replicate the cellular structure of natural cork to allow oyygen permeation to the same levels as that of natural cork.
