Irish Pot Still

Single pot still whiskey is a style of Irish whiskey made by a single distillery using a mixed mash of both malted and unmalted barley, which is triple-distilled in a copper pot stills. Single pot still whiskey emerged as a means of avoiding a tax introduced in 1785 on the use of malted barley. Although this tax was later repealed, the popularity of the style endured until the emergence of blends in the late 19th and early 20th centuries. In the 1800s, single pot still whiskey was the most popular style of whiskey in the world.
