Shochu vs. Soju!
More often than not when I introduce Americans to shochu, they almost invariably think I said soju, and unless they're indiscriminate drinkers they're not that interested in trying "soju" again. Like many Americans, I'd heard of Korean soju long before I'd heard of Japanese shochu. I suppose this is because in the U.S. soju is often available in Korean restaurants while shochu is rarely available in Japanese restaurants.
