Ace the Sake Scene: Rock Your WSET Level 1 in 2026!

Pressing is a crucial step in sake production, primarily aimed at separating the liquid sake from the solid rice mash, known as 'kasu.' During the fermentation process, the koji mold and yeast work on the rice, converting it into alcohol and flavor compounds. After fermentation, the mash contains both liquid and solid components. Pressing extracts the clear liquid, which is the sake, while leaving behind the residual solids. This step is essential for achieving the desired clarity and characteristics of the final product, ensuring that only the liquid portion intended for consumption is retained.

Other choices do not accurately reflect the role of pressing in sake production. Blending flavors is typically done in later stages of production, while fermentation is initiated before pressing. Measuring alcohol content is a separate process usually conducted after pressing when the sake is evaluated for its final specifications.
