Fermentation techniqueAbout
Sake fermentation is a traditional Japanese method that utilizes koji mold to convert rice starch into fermentable sugars, which are then fermented into alcohol by yeast. This process, known as multiple parallel fermentation, occurs simultaneously in the same tank, setting it apart from other fermented beverages like beer and wine. Koji, a type of fungus, plays a crucial role by breaking down starches into sugars, allowing yeast to convert them into alcohol and carbon dioxide. The fermentation process typically lasts between three to five weeks, during which the mixture is regularly mixed and additional ingredients are added to maintain optimal conditions. The brewer must carefully control temperature and humidity to ensure successful fermentation. After fermentation, the liquid is pressed and filtered before being pasteurized and matured for several months. This intricate process allows for a wide range of flavors, from sweet and aromatic to dry and rich, making sake a unique and versatile beverage.
