I didn't think it had anything to do with CBP... I've brought back wine well over the exemption amount (usually from Canada), declared it and occasionally had to pay a few dollars in duty (most of the time they don't even bother.)
When I said customs I was referring to Schengen/ German customs (maybe they have a rule limiting liquor exports outside the EU without a permit, for example). Or maybe it's some sort of a safety concern (and thus a TSA issue).
Given that this doesn't appear to directly pertain to US Airways, I wonder if we might get better responses in the Travel Safety/ Security forum?
