Kaiyō 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 amongst the finest in which to mature whisky. After years of maturing Kaiyō's casks go on a final maturation at sea voyage for up to 3 months, leaving from Osaka Japan. The movement, temperature variation, and air pressue changes aid the mizunara oak in releasing its delicate flavors and aromas.
