We’ve found that a traditional six-pack carrier works well for short trips. You might consider the tote pictured here a bit much, but it can be a good present and offers extra protection and insulation. It also works to throw in your luggage.
Special packaging (look for something called “bottle armor) also makes an excellent present for a beer drinking travelers. A cheaper alternative (maybe for yourself) is to use bubble wrap and thick rubber bands. Even if you aren’t taking beer with you might make room in your bag for packaging to use on the return trip.
