Inspired by the blending pioneers of the early 19th century, John Glaser, the founder of Compass Box, creates original new whiskies by blending different (malt) whiskies of various ages. Glaser invented an entirely new maturation process. After the first maturing on first-fill Bourbon barrels, the whisky is transferred to refill barrels with heavy-duty cask heads from new French oak. 3 toasting levels are applied to obtain more complexity. This second maturation may take up to 2 years.
