Buying Guide

  • Cap size and compatibility: Ensure the caps fit standard 26mm (US) bottles and are compatible with your bottling equipment, whether manual cappers or automatic machines.
  • Oxygen barrier and oxygen scavenging: Look for oxygen-absorbing liners or separating layers to minimize oxidation and maintain beer quality over time.
  • Liner material: PVC-free liners are preferred for those seeking PVC-free products; dry blend liners are common for reliable sealing with glass bottles.
  • Seal quality and sealing lips: Caps with double secure sealing lips provide a better seal on irregular glass finishes and help prevent leakage during storage and transport.
  • Color coding and labeling: Colored or patterned caps (gold, black, white, silver, red, or American Flag) can help differentiate batches, recipes, or aging programs.
  • Labeling flexibility: Blank-cap tops enable easy labeling for batch numbers, dates, or flavor notes without removing the cap.
  • Quantity and storage: Large counts are economical for frequent bottlers, but ensure you have proper storage to prevent moisture exposure and cap deformation.
  • Durability and compatibility: Choose caps designed for compatibility with your chosen bottle type (glass finish) and your bottling workflow to avoid capping issues or cap pop.
  • Environmental considerations: PVC-free options offer peace of mind for those prioritizing non-PVC materials in contact with beer during storage.
