Premium 5-Year #9 Corks – Agglomerated Core with Natural Cork Discs

Our Premium 5-Year #9 Corks are specially designed for wines you intend to age with confidence. Built with an agglomerated cork core and a natural cork disc on each end, they combine structural consistency with the superior sealing qualities of natural cork where it matters most.

The agglomerated core provides uniform density and strength, helping ensure reliable compression and expansion inside the bottle neck. This consistency reduces the risk of uneven sealing and makes them easier to insert cleanly with a proper corker. Surrounding that core are natural cork discs on both ends, the part of the cork that comes into direct contact with your wine and the outside environment.

That natural cork layer is key. Natural cork offers a tighter, more resilient seal against the glass, improving oxygen control and long-term performance. It also reduces the chance of granule exposure to the wine, helping maintain flavour purity and aging stability. For wines that will be laid down for years, that added sealing integrity supports gradual, controlled maturation rather than unpredictable oxygen ingress.

These corks are ideal for structured reds, reserve-style wines, and any batch you plan to cellar for up to five years. While standard #9 agglomerated corks are excellent for shorter-term storage, this premium construction is a smart upgrade when aging potential is part of your plan.

The #9 size fits standard 750 mL wine bottles and requires a corker for proper insertion. Once installed, they provide a secure, professional closure designed for extended bottle aging.

If you’re investing time into crafting a wine meant to evolve, these premium corks help protect that investment from bottling day through the moment you finally pull the cork.
