title_body: Things people put in bottles of liquor or liqueur and are sold commercially?
upvoted_answer: Habushu is a common Japanese liqueur, where they put snakes inside the bottles. There are two methods of inserting the snake into the alcohol. The maker may choose to simply submerge the snake in the alcohol and seal the bottle, thus drowning the snake. Alternatively, the snake may be put on ice until it passes out, at which point it is gutted, bled and sewn up. When the viper is thawed and awakens, it will quickly die in an aggressive striking manner, which is what most producers look for. The manufacturer will then put the habu in an ethanol bath for a month to preserve it.
