  • TOP SERIES should previously receive bottles in order to calculate the required stopper from the analysis of the configuration of the neck of your bottle;
  • TS stoppers should be used on short term (up to 6 months);
  • Store in a well-ventilated room with controlled temperature between 15°C and 20°C and 50% to 70% humidity;

  • Ensure insertion of the stopper is performed smoothly;
  •  Minimize moisture on the inside of the bottle neck;
  • The ideal bottling conditions are: temperature between 15° and 20°C and humidity between 50-70%. Bottling under different conditions may require non standard products, to be specified by TOP SERIES;


  • Ensure the corking machine operates smoothly; 
  • Clean all cork-handling surfaces regularly with chlorine-free products;
  • Ensure all dust is eliminated using air sprays in strategic positions, particularly prior to stopper insertion. Frequent cleaning of the corking device is very important.

  • After bottling, always keep bottle upright; Ideal bottle storage conditions are 15°-25°C at 50-70% humidity;
  • Keep the facilities free of insects;
  • Bottles should be kept in an upright position while stored and during transport
