THE POST OAK Wine Stopper

The stopper is designed for standard wine bottle neck sizes. While it fits the vast majority of traditional red and white wine bottles, it may not be compatible with oversized or non-standard sparkling wine bottles.

The stopper uses a manual vacuum seal mechanism. Once inserted, the rubber rings create an airtight barrier that prevents oxygen from entering the bottle, which helps slow down the oxidation process and keeps your wine fresh for longer.

Yes, the stopper is engineered to be leak-proof. The combination of the durable metal top and the secure rubber sealing rings ensures a tight fit that prevents spills, even if the bottle is stored horizontally in your fridge or wine rack.

Because of the metal construction and rubber seal, we recommend hand washing the stopper with mild soap and warm water. Avoid putting it in the dishwasher, as high heat and harsh detergents can degrade the rubber seal over time.

While it is specifically engineered for standard wine bottles, it can be used for other beverages stored in bottles with similar neck dimensions, such as olive oil or vinegar bottles. However, it is not intended for carbonated drinks like soda or beer.
