I’m beginning to suspect that this is all part of Twining’s policy as the Earl Grey also suffers from what I am starting to call the American Deficit (when the same brand and style of tea has less flavor when purchased in an American Store than when purchased in other countries).
Some fair back and forth testing has confirmed my suspicion. A nice Earl Grey (not the best, but far from the worst) that’s reliably good when purchased from a retailer not located in the United States.
