Hiram Walker’s Ten High 5 Years Old is a 1970s bottling of Ten High bourbon, produced by Hiram Walker in Peoria, Illinois. The bourbon matured for 5 years and was bottled at 86 proof, before being exported for the Italian market. The Ten High brand was introduced shortly after the end of Prohibition in 1933. Its name refers to a method of storing barrels: barrels that are stored at least ten ricks high mature faster than barrels in a lower part of the warehouse. Ten High was the leading brand of Illinois bourbon until the late 1960s, when the bourbon industry declined. The Peoria distillery stopped production in 1973 and completely shut down in 1981. The brand was later produced at Heaven Hill and the Barton 1792 Distillery.
