I have brought back considerable amounts of wine in the past as well. Remember, that the only restriction is on what you can bring in without being subject to duty. So long as you are over 21 and not violating your state's laws. You may find though, that depending upon where you live, you may want to enter the US at a state with more liberal alcohol policies, i.e., Illinois, Washington, California; then one of the more restrictive states like Texas or New York.
