 The "Spot" range of whiskeys are amongst a handful of single pot still whiskeys in existence today, with Green Spot being the only one to have remained in continuous production since the early 1900s (Redbreast, the other long established Irish single pot still whiskey, briefly ceased production in the 1980s).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 declining demand, most Irish whiskeys were either reformulated as blends or discontinued.
