While returning from Thailand, my flight had a stopover in Taipei so I decided to buy a few items at one of the duty free shops. I purchased a large bottle of Bacardi. When I returned home, I twisted the cap off the bottle and discovered it was not sealed. I opened the lid and poured some in a glass. It smelt and tasted of moonshine (brief taste only).

I suspect empty bottles are being collected at possibly bars and refilled with Taiwanese moonshine then sold in the duty free shops as genuine. If you can't control your duty free shops at an airport what does that say for rest of the country?

Anyone else experience this before?

Name and shame them. Send letters to the local press and the airport management.

If the seal was broken I would suspect one of the help had a night out with the real stuff and replaced the liquor with a cheap substitute. Duty free shops can make enough thru sale markup without going this route. Not impossible but not likely in Taipei,my opinion.
