I've done this a few times. Brought back about 72 bottles of Belgian beer that you can't get in the US. Of course for that I took bubble wrap and hard sided suit cases as I knew this is what I was going to do.
I've had no breakage as of yet.
Two biggest concerns.
1. Luggage weight. 50lbs is approx 30 bottles depending on the bottle.
2. Customs, declare what you have and they usually don't even blink, don't declare it and get caught and they can easily confiscate it. You are only allowed 1 liter of duty free alcohol, but that doesn't mean you can pay the duty on the rest if they insist (10% I believe).
