Our best Single Piece All Natural Wine Cork from MA Silva carries the manufacturer's highest strength rating, UF25, and comes in a 100 count bulk bag. Natural wine corks are preferred for all types of wine, aging periods and bottle formats. No other natural product offers this combination of visual appeal, neutrality and consistent sealing qualities. 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 don't expect to keep your bottles corked for over five years, our Twin Disk Corks offer a more cost effective closure while maintaining high quality. If you regularly make wine, it's worth looking into picking up your own Floor Corker.



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 F - 68 F. It is best to use your corks within 6 months.


M.A. Silva aims to exceed the highest standards set in the industry regarding TCA (tricloroanisole)---they have developed an innovate custom-designed cleaning process that volatilizes potential TCA and other off-aroma molecules during the manufacture of their corks. They been voted the best cork supplier multiple time by Vineyard and Winery Management Magazine.  They are certified and follow rigorous quality testing standards.  The Beverage People has supplied home and commercial winemakers with their high quality corks for decades.

Speedy service and great products
Once again The Beverage People saved the day. Ready to bottle my 2018 5 Portughese varietal port and found I only had dual disc. So visited our local shop and bought what the told me were natural corks. When I got them home found they were below grade natural corks filled in with cork dust and glue. Not what I wanted for a port I hope to drink on my death bed 20 years hence. Ordered from Beverage People and received natural cork within two days. Tragedy averted. Thank you!
