The production of Shichiken Namanama Junmai Namazake involves a careful and traditional brewing process designed to retain the sake's fresh characteristics. The brewery begins with premium, locally sourced sake rice, polished to about 70%, ensuring that the purest elements of the grain are utilized. Following the polishing, the rice is washed and soaked to prepare it for steaming. Steaming is critical as it gelatinizes the rice starches, making them more accessible for fermentation. After steaming, koji mold is introduced, allowing for saccharification to occur, where starches convert to sugars essential for fermentation. Yeast is then added to the mixture, and the fermentation process takes place in a controlled temperature environment, preserving the delicate aroma and flavor profile. Because this sake is unpasteurized, it undergoes minimal processing, maintaining the integrity of flavors derived from the natural brewing ingredients. After fermentation, the sake is filtered and bottled without any artificial stabilizers or additives, resulting in a product that embodies the ethos of its natural surroundings.
