Cork stoppers EXPO2 47x29mm for sparkling wines

Both stoppers are perfect for sparkling wines. They’re particularly effective for wines that don’t require extended aging, such as young cava or prosecco.

Yes, natural cork is an excellent choice for sparkling wines:

1. Effectively retains pressure: Its porous and flexible structure allows for optimal pressure retention inside the bottle, crucial for keeping those bubbles intact.


2. Handles temperature fluctuations: Sparkling wines are often chilled before serving, and natural cork performs better than synthetic options in these conditions. It adapts and maintains its seal even after refrigeration.


3. Provides an excellent seal for quick consumption: For wines intended for immediate drinking, natural cork protects against oxygen exposure, minimizing oxidation risk.


4. Natural cork may expand slightly upon insertion, which is essential for withstanding the higher pressure in sparkling wines.


5. Safe opening: Unlike synthetic stoppers, natural cork doesn’t harden over time, allowing for a more secure opening with a lower risk of the cork popping out unexpectedly.

The main design difference lies in the base. EXPO1 features a flatter base, while EXPO2 has a slightly rounded bottom.

In technical terms, EXPO1 absorbs slightly less moisture (≤ 30%) compared to EXPO2 (≤ 40%). They also differ in TCA release: EXPO1 emits less (≤ 1.5 ng/L) than EXPO2 (≤ 2.0 ng/L). Nevertheless, these differences are negligible for sparkling wines consumed quickly.

All EXPO stoppers measure 47 × 29 mm.

TCA, or trichloroanisole, is a compound that can impart a 'corked' flavor to wine. The less TCA present in the stopper, the lower the risk of this occurring. We rigorously test each stopper for TCA levels.

No, TCA is not harmful, so you don't need to worry. Even if it’s present in the wine, it poses no health risk.

No, EXPO stoppers are designed exclusively for sparkling wines that don’t require long aging.

If you’re looking for stoppers for still wines, we recommend:

• SELO – an economical solution with standard TCA levels. Ideal for still wines meant for quick consumption.


• UNIQ – slightly pricier stoppers made from fine cork granules, providing better sealing and lower TCA levels than SELO1 and SELO2.


• UNIQ+ – premium stoppers with nearly zero TCA content, perfect for still wines requiring longer aging.

1. Natural cork ensures a better seal, which is essential for maintaining pressure and preserving the bubbles. It fits more snugly against the bottle neck, minimizing the chance of leaks or loss of carbonation.


2. Cork has natural antibacterial properties, providing added protection for the wine. Synthetic alternatives don’t offer this advantage.


3. Natural cork is more flexible, adapting better to the bottle neck, making for a safer opening with reduced risk of cork popping out unexpectedly, unlike synthetic stoppers.


4. Natural cork is more environmentally friendly – its production consumes less energy and produces less persistent waste compared to plastic stoppers.

Our stoppers are made from natural cork granules, fully safe for food contact. They contain no recycled materials or GMOs.

The entire production process is carefully monitored to comply with food safety regulations. All materials and processes adhere to international standards for cork stopper manufacturing.

No, modern corks are ready to use right away. Soaking was once common for natural cork stoppers, but it's no longer necessary.

It's best to store them on their side to keep the cork moist and ensure a good seal.

Ideally, store the bottles in a cool, dark place with a stable temperature, ideally between 10 and 15°C.

Maintain a humidity level of around 70%, if possible.

Yes, natural cork is one of the most sustainable materials! It is harvested from the bark of the cork oak tree without cutting down the tree. The tree continues to grow and regenerate its bark regularly, a process that can be repeated for decades!

Cork is also fully biodegradable and recyclable. The cork oak forests, where this natural cork is harvested, support a rich diversity of plants and animals.
