  • 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 six 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 15ºC and 25ºC 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 no less than 15,5 mm.
  • Ensure insertion of the cork is a quick as possible.
  • For standard bottlenecks, the cork should be inserted at 25 mm ±1 mm from the top of the neck with the wire wood applied.
  • Minimise moisture om the inside of the bottleneck.
  • Headspace should be at least 15 mm at 20ºC.
  • 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 for at least 5 minutes.
  • Ideal bottle storage conditions are 12o-18oC at 50-70% humidity.
  • Keep the wine cellar free of insects.
  • Bottles should be transported in an upright position.
  • The product must not be stored in a location exposed to sunlight, in a heated environment and in direct contact with the ground.
