Metal Stopper vs Cork: Why Spirits Brands Are Switching to Zamac
Natural corks dry out and crumble. A well-made metal stopper offers a different answer: an airtight, vacuum-like seal that blocks oxygen — the main cause of flat taste and spoilage.
Instead of relying on cork, metal wine stoppers use a flexible food-safe insert (silicone, rubber, or cork) that compresses tightly into standard bottle necks. They prevent leaks, lock in aroma and flavor for days or even weeks after opening, and are reusable and easy to clean.
Zinc alloy (zamak) is the material to choose for premium stoppers:
- Complex shapes, engravings, and details that other metals cannot match
- Corrosion, tarnish, and bend resistance that lasts for years with proper care
- Finishes from polished and plated to antique gold, silver, bronze, or matte black
- Versatile across red wine, white wine, sparkling, and spirits — fits all food-grade bottles
