I used to always bottle samples in beer bottles so I could see how wine was aging. Only reason I didn't do that nonw (just started on wine again) is because I forgot to get any caps.
The beer bottles also were nice for individual servings. Gave two glasses, just about right for wine with dinner. Or wine on the train. Joys of being a commuter.
But if you want to seem less of a barbarian, just call them splits instead of beer bottles.
