It is also used Mongola, known as Japanese oak, purchased in Meigi City, Hokkaido. It is processed and charled in the same way as actual whiskey making. When placed in whiskey, the flavor will be removed in about 24 hours, and the flavor will be better. Includes 5 Mongolian sticks with a 0.4-inch (10 cm) square length. Can be placed directly into a whiskey jar. It is easy to see the change of flavor when soaked for about a week. Charring is done to the smallest of charcoal to prevent the flavor of wood.
