JPDuo stoppers consist of a cylindrical body of agglomerated cork and two natural cork discs at each end, glued together.

The discs are produced from thin corkwood (slow growth), providing high elasticity and excellent sealing.

They have a homogeneous visual quality, are chemically stable and mechanically resistant. They have excellent performance in both sealing properties and high organoleptic neutrality.

They are stoppers with an excellent price/quality ratio, recommended for wines consumed up to 4 years after bottling.
