Our Single Piece Natural Wine Cork from M.A. Silva with Chamfered Edges is intended for use with the Double Lever Corker we carry. This cork carries the manufacturer's strength rating UF30, a moderate grade. Natural wine corks are preferred for long aging wines.  Being made from a single piece of cork means you're getting superior durability and longevity, which translates to more confidence in the shelf life of your wine.

If you are bottling white wine, more delicate red wine, or don't expect to keep your bottles corked for over five years, our Twin Disk Corks or Pearl Micro Agglomerated corks may be a more appropriate choice while maintaining high quality.

If you are uncertain which cork type is the best choice for your wine, please read our discussion on Managing Oxygen Before & After Wine Bottling.  This article includes a vital discussion that will help you identify the best cork for your circumstances.

To ensure we are providing our customers with fresh and excellent quality corks, we generally keep no more than a two month stock of corks on hand. The corks are manufactured upon request for us, thus you can rest assured that the corks we are providing you are recently manufactured and packaged. Once in your possession, you should take care to reseal if possible and store your corks cool---ideally 59 ºF - 68 ºF. It is best to use your corks within 6 months.
