If you are running a spirits brand, your worst nightmare isn't a bad marketing campaign. It’s a call from the filling line telling you that your premium gin is leaking from the neck. Let me tell you a real story from a client in New Zealand. They tried to save a few pennies by sourcing glass bottles and 30*60 aluminum long caps from two completely different factories. The glass factory didn't control the thread tolerance tightly enough. The result? When the automated capping chucks came down at 120 bottles per minute, the aluminum skirt split open like a cracked eggshell on 30% of the line. The capping heads were jammed every 5 minutes, sticky gin was pooling all over the conveyor, and 1,000,000 bottles became pure warehouse deadstock.
