Manufacturers take baby mice from their mothers before they begin to grow hair or open their eyes and place them, alive, in bottles of rice wine. There the little critters are left to drown, sink to the bottom of the bottle, and ferment, along with the wine, for 12 to 14 months.
Quality wine contains not one, but between 12 and 14 mice per bottle. Upon finishing the wine, one is also supposed to eat the pickled rodents. The concoction is believed to have strong medicinal qualities and is supposed to cure almost everything that ails you.
It is also said to taste a lot like gasoline.
