James Eadie began producing this expression in 1854, and trademarked the cross logo in 1877. Trade Mark X was produced until the late 1940's, then disappeared. The brand was relaunched by Eadie's great-great-grandson, with a recipe that contains 14 of the 16 whiskies that appeared in the original Trade Mark X, including a few now closed distilleries. Bottled at 45.6%.
