The art of sealing sparkling wines

Spark® Top II

Excellent mechanical behavior

This technical cork stopper is made up of a granulated body, obtained by individual moulding, to which are added two natural cork discs, which act as a protective barrier in contact with the wine.

The Spark® Top II stopper undergoes two technological cleaning processes. ROSA for the cork granules and CorkNova for the discs, which ensure a stopper with excellent performance, capable of guaranteeing the evolution of sparkling wine in the bottle over decades.

  • 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
