Closures, consistency, and building brand equity

The influence of wine closures on wine quality has been  thoroughly studied over the last two decades. And while cork taint caused by unwanted migration of TCA into the wine is still a Sword of Damocles for wine quality, new technologies exist that can eliminate some of those TCA risks. This is why consistency of closure type is pivotal, impacting not only wine quality, but also brand equity through its control over bottle-to-bottle variation.  The optimal closure can positively influence wine evolution, shelf-life, and style of wines reaching the final end consumers.   Wine bottle closures are also very important winemaking tools (shaping style), quality ambassadors (avoiding defects and promoting consistency), and marketing vehicles ( a key component of packaging and connection with customers).

  • Closures as quality ambassadors: Bottle-to-bottle consistency and no closure-related wine fault
  • Closures as winemaking tools: Ensuring the wine will be enjoyed as the winemaker intended
  • Closures as marketing vehicles: The message in the bottle to engage with your customers
