Taking Tradition into the FutureRAI is created using a new age labor-intensive production process with the yeast, koji and lactic acid being the keys to this rich brew. Timing of the additions to the starter mash influence the flavor and aroma. Ozeki exclusively developed a new way of making sake to bring out the savoriness while sustaining easy drinkability. The unique brewing process of RAI creates a pleasant earthiness that is not too bold nor meek with subtle hints of caramel in the nose. A straightforward flavor that can be enjoyed for hours.
