BackSpark® Top II The art of sealing sparkling wines
Excellent mechanical behavior
The Spark®Top II stopper benefits from technological processes that ensure the best sensory performance. ROSA and FBT for the cork granules and CorkNova for the discs
guarantee a stopper with excellent performance, offering the best results in terms of pressure resistance and preservation of the wine's aromatic quality.
The discs used also benefit from X-ray mass analysis control, which contributes to their physical and mechanical performance.
Spark®Top II is the cork preferred by most winemakers, offering the best compromise between physical and mechanical performance, aesthetics and sensory characteristics.

- Amorim can calculate the required cork diameter by studying the internal profile of the bottleneck, the characteristics of the wine and the corking conditions.
- Order your cork stoppers for immediate or short-term use. Ideally, these cork stoppers should be used within four months of the date of manufacture if the storage conditions are respected.
- Store the cork stoppers in their original packages, in a well-ventilated room with controlled temperature between 15°C and 25°C and 50% to 70% humidity.
- Do not leave boxes and/or bags open with surplus cork stoppers.
- Ensure any dust its removed before corking.
- Ensure the cork is compressed smoothly, to a diameter 1.5 to 2 mm smaller than the diameter of the bore of the bottle.
- Ensure insertion of the cork is as quick as possible.
- For standard bottlenecks, the cork should be inserted at 24 mm ± 2 mm from the top of the neck with the wire wood applied.
- Minimise moisture on the inside of the bottleneck.
- Don’t leave the cork stoppers in the feeder as to avoid dust.
- Always use stoppers with a surface treatment suitable for the type of beverage, bottling process and selected bottle.
- Ensure that all dust is removed using suitable placed aspiration – particularly before inserting the cork stopper.
- Maintain the corker jaws free of nicks and signs of wear.
- Ensure proper alignment of plunger and location ring.
- Ensure corking machine operates smoothly, especially during compression.
- Clean all cork-handling surfaces regularly with chlorine-free products.
- Ensure the equipment is suited to the cork and bottle used.
- After bottling, the bottles should be kept in an upright position.
- Ideal bottle storage conditions are 12–18°C at 50–70% humidity.
- Keep the wine cellar free of insects.
- Bottles should be stored and transported in an upright position for better preservation of cork recovery after extraction.
- The product must not be stored in a location exposed to sunlight, heated environment and in direct contact with the ground
