The vacuum wine sealer requires the Zwilling Fresh & Save Vacuum Pump (sold separately) to function effectively. The sealer creates the airtight seal on the bottle, whilst the pump extracts the air to create the vacuum environment. Together, they form a complete wine preservation system. You can purchase multiple sealers for different bottles whilst using a single pump.

The 3cm diameter is designed to fit standard wine bottle openings, which covers the vast majority of still wine bottles including Bordeaux, Burgundy, and standard screw-cap bottles. However, some speciality bottles with non-standard neck dimensions or very narrow openings may not accommodate the sealer. Champagne and sparkling wine bottles are not suitable for vacuum sealing regardless of fit, as these require pressure retention rather than vacuum preservation.

Zwilling claims the vacuum sealing system keeps wine fresh significantly longer than conventional recorking, though exact duration depends on wine type and initial condition. Delicate whites and light reds typically show more dramatic preservation benefits than robust, tannic reds. Most users find vacuum-sealed wines maintain quality for 5-7 days refrigerated, compared to 2-3 days with standard recorking. However, vacuum sealing slows oxidation rather than stopping it entirely, so wines won't last indefinitely.

Yes, the vacuum sealer works effectively for oils and fresh juices - any non-carbonated liquid that deteriorates through air exposure. Premium olive oils, in particular, benefit from vacuum sealing as oxidation causes rancidity and flavour degradation. Fresh-pressed juices maintain vitamins and fresh taste longer when air is removed. Do not use this system for carbonated beverages like sparkling wine, beer, or fizzy drinks, as vacuum extraction removes the carbonation that defines these drinks.

The number of sealers you need depends on how many bottles you typically have open simultaneously. If you usually have just one bottle open at a time, a single sealer suffices. If you regularly have multiple wines open - perhaps a red and a white, or several bottles during entertaining - purchasing multiple sealers allows you to preserve each bottle without moving the sealer between bottles. The sealers remain on the bottles between uses, with the pump moving from bottle to bottle as needed.

Standard delivery to mainland UK addresses typically takes 3-5 working days. Next day delivery may be available for £9.95 on orders placed before 1pm Monday to Thursday, depending on your location and our stock levels. We pack all items carefully with protective packaging to ensure safe arrival.

We offer a no quibble return guarantee that allows you to return goods even after use. The items must be in a resaleable condition and in their original packaging. If you've tested the sealer and found it doesn't fit your particular bottles, you can return it following our standard return process. Please wrap or box items appropriately for transit.

Yes, the vacuum pump is sold separately from the sealers. This allows you to purchase the number of sealers you need whilst using a single pump. If you're new to the Zwilling Fresh & Save system, you'll need both the vacuum pump and at least one sealer to create a functional wine preservation system. We may offer bundle options that include both components - check product variants for available configurations.

When functioning correctly, you should hear a distinct "whoosh" of air when you break the seal by lifting the sealer tab. If the sealer removes easily without this sound, the vacuum may not have been properly achieved. Ensure the sealer sits flush against the bottle opening and that the vacuum pump is fully charged. If wine deteriorates as quickly as it would with simple recorking, the seal may be compromised and the sealer may need replacement.

The 24-month manufacturer warranty covers defects in materials or workmanship under normal use conditions. This includes seal failure due to manufacturing defects, material degradation beyond expected wear, or coating separation. The warranty doesn't cover damage from misuse, dropping, or normal wear from regular use. If you experience issues with your sealer, contact us with your proof of purchase and we'll guide you through the warranty claim process.

Yes, the vacuum sealer works with screw-cap bottles provided the bottle neck diameter matches the 3cm sealer diameter. Once you've removed the screw cap, place the vacuum sealer on the bottle opening just as you would with a traditional cork-finished bottle. The sealer creates its own seal regardless of the bottle's original closure type. Save the original screw cap for situations where you need to transport the bottle, as vacuum sealers are designed for upright refrigerator storage.

With proper care and regular cleaning, vacuum wine sealers typically provide years of reliable service. The stainless steel coating provides durability, and the dishwasher safe construction means thorough cleaning without hand-washing wear. Lifespan depends on usage frequency - someone preserving wine daily will experience more wear than occasional users. Signs that replacement may be needed include difficulty achieving vacuum seal, visible damage to the seal mechanism, or faster wine deterioration despite proper vacuuming.

Yes, refrigeration is recommended for all vacuum-sealed wines regardless of type. Whilst red wines are traditionally served at room temperature, once opened they benefit from refrigeration to slow oxidation further. Simply remove the sealed bottle from the fridge 30-60 minutes before serving to allow red wines to warm to appropriate drinking temperature. White and rosé wines can be served directly from the fridge. The vacuum seal combined with cool temperature provides optimal preservation conditions.
