IMPORTANT UPDATE:

Good news for those wanting to bring back a nice quantity of their favorite Argentine wines to the US. Here is the official rule explained on the TSA website. The 5 liter rule applies to flammable products, but wine is not one of the substances that is regulated because it does not fit into the alcohol content category.

Please see below in RED the limitations for hard licquor, and in BLUE the explicit exclusion of liquids such as wine that are below 24% alcohol content:

Carrying Alcohol In Your Checked Baggage

Please note, you can’t take alcoholic beverages with more than 70% alcohol content (140 proof), including 95% grain alcohol and 150 proof rum, in your checked luggage.

You may take up to five liters of alcohol with alcohol content between 24% and 70% per person as checked luggage if it’s packaged in a sealable bottle or flask.

Alcoholic beverages with less than 24% alcohol content are not subject to hazardous materials regulations.
