Got questions? We’ve got you covered.
WHAT TYPES OF WINES WORK BEST WITH EXPO1 AND EXPO2?
Both stopper options are specifically developed for sparkling wines. They are especially suitable for wines intended for early consumption, such as prosecco or young cava.
CAN NATURAL CORK BE USED FOR SPARKLING WINE?
Absolutely — natural cork performs exceptionally well with sparkling wines:
- Helps maintain internal pressure: Its flexible and slightly porous structure allows it to hold pressure effectively, keeping carbonation intact.
- Handles temperature shifts well: Whether chilled or stored, natural cork adapts without losing its sealing properties.
- Provides reliable sealing for short-term storage: It limits oxygen exposure, helping preserve the wine’s freshness.
- Expands after insertion: This natural elasticity ensures a tighter seal, especially important for carbonated wines.
- Safe and easy to open: Unlike some synthetic closures, it remains flexible, reducing the risk of sudden popping.
WHAT’S THE DIFFERENCE BETWEEN EXPO1 AND EXPO2 STOPPERS?
The main visual distinction is in the base design. EXPO1 features a flatter bottom, while EXPO2 has a slightly rounded profile.
From a technical standpoint, EXPO1 absorbs slightly less moisture (≤ 30%) compared to EXPO2 (≤ 40%). It also has a lower TCA release level (≤ 1.5 ng/L vs. ≤ 2.0 ng/L). For wines consumed relatively quickly, however, these differences are minimal — both options perform reliably.
WHAT SIZE ARE EXPO SPARKLING WINE STOPPERS?
All EXPO stoppers measure 47 × 29 mm.
WHAT DOES TCA MEAN?
TCA (trichloroanisole) is a compound that can occasionally cause a musty or “corked” flavor in wine. Simply put — lower TCA levels mean a lower risk of this issue. That’s why every stopper is carefully tested to meet strict quality standards.
IS TCA HARMFUL TO YOUR HEALTH?
No, TCA does not pose any health risk. Even if present, it only affects taste — the wine remains safe to drink.
CAN EXPO STOPPERS BE USED FOR STILL WINES?
No — EXPO stoppers are designed exclusively for sparkling wines that are not meant for long ageing.
For still wines, consider the following alternatives:
- SELO1 and SELO2 — budget-friendly options with standard TCA levels, ideal for wines consumed sooner.
- UNIQ2, UNIQ3, UNIQ4, UNIQ5 — higher-grade corks made from refined granules, offering better sealing and lower TCA levels.
- UNIQ4+ and UNIQ5+ — premium solutions with near-zero TCA content, perfect for wines intended for long-term ageing.
WHY CHOOSE NATURAL CORK OVER SYNTHETIC STOPPERS?
- Superior sealing performance: Natural cork conforms to the bottle neck, helping maintain pressure and prevent gas loss.
- Natural antimicrobial properties: Cork offers added protection that synthetic options don’t provide.
- Greater flexibility: It adjusts better to the bottle and reduces the risk of sudden release when opening.
- Environmentally responsible: Cork production is sustainable and generates less waste compared to synthetic alternatives.
WHAT ARE THESE STOPPERS MADE OF?
They are produced from natural cork granules, making them fully safe for food contact. No recycled materials or GMOs are used.
Production is carefully controlled and follows international food safety and cork manufacturing standards.
DO I NEED TO PREPARE THE CORK BEFORE USE?
No preparation is needed. Modern cork stoppers are ready to use straight out of the box.
HOW SHOULD WINE WITH NATURAL CORK BE STORED?
Store bottles on their side to keep the cork moist and properly sealed.
Keep them in a cool, dark environment with a stable temperature — ideally between 50–59°F (10–15°C).
Maintaining around 70% humidity is also recommended.
IS NATURAL CORK SUSTAINABLE?
Yes — natural cork is one of the most sustainable materials available. It’s harvested from cork oak bark without harming the tree, allowing it to regenerate naturally over many years.
Cork is biodegradable and recyclable, and cork forests support rich ecosystems full of biodiversity.
It’s easy to assume that a wine cork is just a minor detail — but in reality, it plays a crucial role. No other closure matches its performance. Wine isn’t just about taste — it’s about experience, atmosphere, and shared moments. That’s exactly why choosing the right sparkling wine stopper matters.
#1 PURELY NATURAL — NO SYNTHETICS
Ever opened a bottle and wondered why there’s plastic inside something meant to be premium? It just doesn’t feel right. Natural cork is the authentic choice — it doesn’t just seal the bottle, it helps protect and enhance what’s inside.
Cork isn’t a cheap, mass-market substitute. It’s a time-tested material that has been trusted for centuries — long before synthetic alternatives ever existed. It combines natural origin with proven performance.
#2 A HEALTH-CONSCIOUS OPTION
What seals your wine matters more than most people think. Natural cork stands out as a safe and clean solution — free from artificial components.
Our cork stoppers are GMO-free and fully meet food safety standards. That means you can enjoy every bottle with confidence, knowing nothing unwanted is affecting your wine. It’s reassurance you simply won’t get from plastic closures.
#3 MORE THAN OPENING — IT’S AN EXPERIENCE
Uncorking a bottle is part of the ritual — not just a step before drinking. Twist-off caps may be convenient, but they lack character. Natural cork brings tradition, anticipation, and a sense of occasion.
Every cork has its own natural look and texture, with unique tones and patterns. No two are identical. That individuality adds a distinctive touch to every bottle. EXPO stoppers reflect that natural variation — each one slightly different, just as nature intended.
#4 ENGINEERED FOR PERFORMANCE
Each stopper is crafted from carefully selected cork granules and shaped for an optimal fit. This is especially important for sparkling wines, where maintaining pressure is key. The stopper must balance strength, flexibility, and tight sealing.
Strict quality checks ensure consistency and reliability. This minimizes the risk of leaks, oxidation, or loss of carbonation — so your wine stays exactly as it should.
#5 A SUSTAINABLE CHOICE
Natural cork is fully biodegradable, meaning it won’t contribute to long-term environmental waste. Unlike plastic, it naturally breaks down without harming the planet.
Additionally, cork oak forests are vital ecosystems. In Portugal — the world’s leading cork producer — these areas support over 135 species of plants and animals, including rare wildlife such as the Iberian lynx.
