Tenjaku Whisky Pure Malt - made with corn and barley, and aged in American white oak bourbon barrels. 天雀 – the Japanese characters for the skylark (hibari), the much-loved herald of spring in the East and West, and for this masterfully blended whisky. Like the clear, exquisite song of a small bird, it features an agreeably pure, mellow flavor. Carefully selected unprocessed whiskies and pure, natural spring water are expertly blended to create this distinctive whisky.
