Did you know that the closure of a wine can have an impact on the overall drinking experience? Traditionally, wine is sealed with a cork, but screw caps have become increasingly popular in recent years. But which closure is actually better for the wine, or is it even possible to say?
The cork: tradition meets nature
The cork stopper is the classic wine stopper and has been used for centuries. Made from the bark of the cork oak, the cork is characterized by its natural flexibility and breathability. These properties have a decisive influence on the maturing process of wine.
Advantages of cork:
- Breathability: Did you know that wine corks do not allow oxygen to pass through? The cork stores tiny amounts of air in the smallest cork cells. This micro-oxidation can help the wine to develop and mature over time. This is a particularly important factor for high-quality wines that are stored for years.
- Tradition and prestige: Cork has a long tradition in viticulture and is often associated with high-quality, fine wines. For many wine drinkers, this aspect plays a major role in their choice of wine.
- Ecological footprint: Compared to other closures, cork oaks absorb part of the CO2 emissions from production.
Disadvantages of cork:
- Cork taste: In a few cases of wine bottles, the cork can contaminate the wine with an unpleasant "cork taste". This is caused by a certain chemical substance in the cork (TCA). However, thanks to innovations and technologies, the threshold value for the perception of TCA has fallen sharply.
- Cost: Natural corks are relatively expensive to produce and the production of corks also has an impact on the environment as they are a resource that is not available in unlimited supply.

The screw cap: Modern and practical
The screw cap is a more recent development and has become particularly popular for younger, fresh wines. It is made of aluminum and a plastic seal and offers many practical advantages.
Advantages of the screw cap:
- Safe and easy to handle: The screw cap is particularly user-friendly. Unlike a cork, it does not need to be pulled, which makes opening and closing the bottle much easier.
- No wine faults: screw caps eliminate the risk of cork taint.
- More cost-effective: Screw caps are cheaper to produce, which is particularly advantageous for wines in higher quantities and in lower price segments.
Disadvantages of the screw cap:
- Restricted maturation: The screw cap hermetically seals the wine, which means that the wine does not come into contact with oxygen and maturation is inhibited.
- Less prestige: Although the screw cap is becoming more and more established in the industry, it is still not associated with the same elegance and prestige as the cork.
Conclusion: Which fastener is the right one?
The choice between cork and screw cap depends entirely on your taste and the wines you prefer. If you have a wine that needs to age for a long time and appreciate the traditional, festive aspect, cork is a good choice. Especially if you want the wines to benefit from micro-oxidation during the ageing process.
If, on the other hand, you prefer practical, uncomplicated access to your wine, especially for wines that should not be altered by oxygen in the bottle, then the screw cap is a good option.
Both closures have their place, and the decision is ultimately up to you. Pay attention to which closure is used for your next wine and be inspired by the different options!
