From the importer:
Senkin Modern Muku is the brewery's flagship brand, brewed 100% with local Sakura city Yamada Nishiki rice. Part of their "modern" series (meaning that it was brewed with modern methods), the brewery touts this as their daily drinking sake - one that fits in your class as comfortably as wearing a clean white shirt. Muku, meaning pure or innocent, refers to a lack of excessive embellishment in the sake. It has a sharp, vibrantly fruity flavor with a well-balanced umami heft, and the brewery encourages drinkers to try enjoying their sake out of Bordeaux wine glasses to maximize the sensory potential of the brew.
