This eco-friendly stopper made from natural cork is an ideal choice for both home and professional winemakers. Its conical shape and carefully selected dimensions make insertion easy and ensure a reliable seal for the neck of a 5 l glass demijohn. The natural material minimizes the risk of affecting the taste and aroma of stored beverages.
Before use, we recommend briefly preparing the stopper: soak it for about 3 minutes in hot water or hold it over steam. This increases the cork’s flexibility and makes insertion easy and gentle. After sealing, keep the vessel in a vertical position for 24 hours to let the stopper settle properly. Then store it horizontally—the cork will not dry out and natural gas exchange is ensured.
