 Redbreast is one of a handful of single pot still whiskeys in existence today and one of only two to have been produced almost continuously since the early 1900s (the other being Green Spot).Although once the most popular style of whiskey consumed in the world, pot still whiskey fell out of favor in the 20th century, due in part to the rise of cheaper, less intense blended whiskeys.As a result of falling demand, most Irish whiskeys were either reformulated as blends or discontinued.
