Cork Supply is committed to making the most of what Mother Nature gives us. We start with the finest cork wood and invest in state-of-the art technologies at each stage of the process, from forest to bottle, to guarantee corks of the highest quality. The CS Natural is the traditional one-piece cork closure that combines performance, appearance, and sustainability. All our CS Natural corks are processed by the Innocork Circuit to give it a maximum sensory performance. It is natural choice for any still wine today and tomorrow.
