Wine.
I previously flew a Falcon for a vineyard regularly around the world, usually departed home base with over 20 cases and it was a PITA when stopping somewhere hot or cold having to remove it all for storage. It was also interesting listing it as ships stores.... raised a few eyebrows from time to time.
Part of it was marketing, like taking a bunch of New York wine critics for a 90 min low level joy flight over up state getting them tanked. The reviews were spectacular and sales went up over 400% in the region, certainly kept the boss happy.
