Generally, one liter per person may be entered into the U.S. duty-free by travelers who are 21 or older, although travelers coming from the U.S. Virgin Islands or other Caribbean countries are entitled to more.

Additional quantities may be entered, although they will be subject to duty and IRS taxes.

Duty is generally 3% of value and the IRS excise tax is generally between 21-31cents per 750ml bottle of wine, 67 cents/champaigne, and $2.14/ hard liquor.

It is not legal for travelers under the age of 21 to import alcohol - even as a gift.
