agglomerated twin disk wine corks

About the Twin Disk Wine Corks from Xiberta:

Xiberta's Twin Disk Wine Cork is a popular hybrid cork for bottlings destined for short to medium aging. It is constructed of an agglomerated cork core sandwiched between two solid cork pieces. The two solid cork end caps mean that wine is never in contact with the Food-Grade adhesive during cellaring.

Twin Disk corks are ideal for white wines, light reds, still ciders, and meads.

If you are bottling a robust red wine, or expect to keep your bottles corked for over five years, our All Natural corks may be a more appropriate choice to allow bottle maturation and an extended shelf life.

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.

Customer for 28 years 02/15/2020

I have ordered wine, beer, and cidermaking supplies from The Beverage People for over 28 years. I love The Beverage People and won’t order from on line companies because:

I can order corks that don’t have cutesy pictures of grapes on them

I can order chromatography solvent without ordering the glass jar and standards

They offer hands on advice and workshops not on line tutorials.

They are local and community based.

Byron and Nancy were my first teachers and you guys carry on.
