While you'll probably be just fine, there are also some really crazy interstate laws when it comes to transporting wine. Florida actually considers it a felony to ship wine from another state directly to a consumer - even if it's a gift from a friend. You can ship from abroad if you obtain some special permits.

Carrying it into Florida, they allow you to bring in one gallon of wine/alcohol tax-free. You must be able to prove you purchased it outside the state. But I really can't imagine you being checked on an interstate trip.
