There is no question on the paper form or at the GE kiosk specifically about alcohol. You don't even need to choose an option at the kiosk that will get you an X unless the value of the alcohol is going to put you over your $ value exemption for goods. Getting the X means you have to see a passport officer..just skip that and go to the customs line and you can declare it there if you want.

If you're not bringing back cases of booze or very expensive booze.. they're not even going to waste their time collecting duty of a few $ per bottle.
