Kaiyo whisky is matured in the finest Japanese Mizunara oak casks. These casks are handmade due to Mizunara oak’s delicate wood grain. They are among the rarest casks in the world and are considered the finest in which to mature whisky. After years of maturing our casks go on a final maturation at sea voyage for up to 3 months, leaving from Osaka Japan. Kaiyo Japanese Whisky has a delicate nose of vanilla, ripe dried fruit and hints of cherry, with a long lingering finish.
