saké is an alcoholic beverage of Japanese origin that is made from fermented rice. Sake is sometimes called "rice wine" but the brewing process is more akin to beer, converting starch to sugar for the fermentation process.
Sake or Nihonshu, the so called "Japanese rice wine", is traditionally considered as a sacred alcoholic beverage. We have the custom to hit and break open the lid of a sake barrel by a wooden mallet, which is known as Kagami Biraki (open the mirror) to celebrate happy events, such as weddings, store opening events, ritual events held at shrines, and so on.
Ginjo-shu is a type of sake that is well-known for its pleasant smell. With its full, rich flavor, it is most often enjoyed hot. This infographic from a Japanese steakhouse in San Jose has more information about sake.
