Do bottles smaller than 750ml of Maraschino even exist in the US? I've seen a few unsubstantiated online references to smaller bottle sizes, and my liquor store is checking to see if they can order it, but no one seems to stock a smaller size.
The same seems to go for Creme de Violette and other less-popular liqueurs. I can easily use up 750ml of a liqueur like Cointreau, but I can't see myself EVER needing that much Creme de Violette. I think I'd be happy for a long time with just a 50ml nip.
